According to the National Alliance for Caregiving, more than 22 million†¦show more content†¦Caregivers who were responsible for both children and parents reported that while children are learning and growing and may become self-sufficient in the future, elderly relatives are usually declining in health and becoming more dependent each day (Baron, 2001). Watching the decline of a loved one, usually a parent, adds additional emotional stress to the stress already felt by what may seem to be a never-ending active schedule. According to studies cited in the Journals of Gerontology (2001), over half of older patients who meet eligibility requirements for nursing home care live at home (Covinsky, Eng, Lui, Sands, 2001). This translates into an economic value of 196 bill ion dollars worth of informal health care provided by caregivers yearly. If this were counted as part of the national health care expense, it would increase estimates of total spending by at least 20 percent if not more (Covinsky, et al, 2001). Unfortunately, other than the peace of mind that they may have for keeping their family at home, caregivers are not compensated for their time or financial sacrifices, and as referred to above, often penalized by their employers for taking time off to care for their parents (Kossek, 2001). It has been estimated that the unpaid labor, lost wages, and missed opportunities for caregivers is equivalent to approximately $4.8 billion per year (Singleton, 2000). These remain hidden costs in the ongoing dialogue regarding care of the elderly in thisShow MoreRelatedChallenge of Taking Care Elderly Loved One Essay952 Words   |  4 Pageshome.

Chemical dispersants are substances applied to spilled oil that disperse oil into the water column rather than leaving it floating on the surface in a slick. When used appropriately, chemical dispersants can be an effective method of response to an oil spill. Following dispersant application, wave energy will cause the oil slick to break up into smaller oil droplets that are rapidly diluted and subsequently biodegraded by micro-organisms occurring naturally in the marine environment. Dispersing spilled oil into the sea by the use of oil spill dispersants can be an environmentally acceptable method of oil spill response. A â€Å"net environmental benefit† will be achieved if the damage that might be caused to marine life by dispersed oil is less than the damage that would have been caused if the oil had come ashore or drifted near to particularly oil-sensitive resources. This justification for dispersant use cannot, however, be imported into every oil spill scenario. Dispersing spilled oil in some circumstances might have the potential to damage marine life that exists in the close vicinity of a dispersing oil slick. Dispersed oil droplets and the chemical components in oil that are transferred into the sea have the potential to exert toxic effects, but only if the oil is present at high enough concentration for prolonged periods. This will only occur if there is not sufficient dilution of the dispersed oil and oil components into the sea. This report amongst other things aims to give an overview of the effectiveness of these oil spill dispersants in bio-remediating oil spills, the types and generations of dispersants available, their toxicity and preference of one mode/type over the other(s). . 2 BACKGROUND ON THE CHEMICAL COMPOSITION OF DISPERSANTS Dispersants are chemical formulations which reduce the surface tension of water allowing the oil to disperse into small droplets in the water column. The dispersants which are available on the market today comprise several components, the most important being a blend of two or three surfactants (surface active agents). Other components of dispersants include the solvent (the carrier of the surfactant) and additives. SURFACTANTS ( SURFACE ACTING AGENTS) The surfactant molecules are the key component of chemical dispersants. Surfactants bind to both oil and water to produce finely dispersed droplets of oil-surfactant molecules. The most common surfactants used are non-ionic (fatty acid esters and ethoxylated fatty acid esters) and anionic (sodium alkyl sulphosuccinate). Surfactants are made up of two parts: an oleophilic or rather lipophilic part (oil loving) and a hydrophilic part (water-loving). When dispersants are sprayed onto an oil slick, the solvent transports and distributes the surfactants through the oil slick to the oil/water interface where they re-arrange so that the oleophilic part of the molecule is in the oil and the hydrophilic part is in the water. This creates a sharp reduction in the surface tension of the oil/water interface and small oil droplets break away from the oil slick with the help of wave energy. Re-coalescence is minimised by the presence of the surfactant molecules on the droplet surface and the reduced probability of encountering other oil droplets as they move apart. There are several different basic chemistries of surfactants. An example of each class is as shown: (1. ) Ethoxylated fatty amines (Cationic) (2. ) Alkylphenol ethoxylate-based surfactants (non-ionic) These surfactants usually include an alcohol as a solvent (isopropanol (X-77 ®, AG-98â„ ¢), butanol (R-11 ®, AG-98â„ ¢ (N)), glycol (AG-98â„ ¢ (N), Activator 90)), a silicone defoamer (polydimethylsiloxane), and water. (3. ) Alcohol ethoxylate-based surfactants (non-ionic) (4. ) Sodium alkyl sulphosuccinate (anionic) (5. ) Silicone-Based Surfactants. Also known as organosilicones, these are increasing in popularity because of their superior spreading ability. This class contains a polysiloxane chain. Some of these are a blend of non-ionic surfactants (NIS) and silicone while others are entirely silicone. The combination of NIS and a silicone surfactant can increase absorption into a plant so that the time between application and rainfall can be shortened. Examples: Sylgard ® 309 , Dyne-Amic ®, Silwet L-77 ® , etc. Blends normally include an alcohol ethoxylate, a defoamer, and propylene glycol. SOLVENTS Solvents must be used because the surfactants are often viscous or solid, and are either hydrocarbon-based or water-based. Modern dispersants are a blend of surfactants in a solvent. The solvent has two functions: * It reduces the viscosity of the surfactants which enables it to be sprayed and, * It promotes the penetration of the surfactant into the oil slick. ADDITIVES Another important component, the additive stabilizes and prevents the oil particle from breaking away from the border area between the oil and the water. These additives are also referred to as stabilizing agents. CHAPTER 2 2. HISTORY OF DISPERSANT Before 1970, chemical dispersants were degreasing agents that were developed to clean tanker compartments and engine rooms. The TORRY CANYON spill off Cornwall, England in 1967 resulted in the use of 6,000 barrels of chemical used to treat a spill of 85,500 barrels of oil. Many of these chemicals were degreasing solvents and were more toxic than the oil itself. The denser surfactants did not evaporate, mix with, or dissolve in water. Instead, they formed a stable â€Å"oil-detergent† emulsion that had a negative synergistic effect causing more harm to the environment than had they done nothing. There was a significant impact to the marine and coastal environment with resulting massive kill off of fish and intertidal invertebrates. Over 10,000 tons of detergents were sprayed on the floating oil. The result of the negative media attention was a poor public image of chemical dispersants. Future dispersant usage saw increasingly better results. In 1979 the Ixtoc 1 spill released more than 3. 5 million barrels of oil. Almost 500 aerial missions were flown applying the dispersant COREXIT 9527 to 1,100 square miles of slick. While dispersants were not used in the US waters, there was successful application of dispersants seen. 2. 2 DISPERSANT REFORMULATION While dispersant application was becoming increasingly more successful, dispersants were being reformulated to address concerns for efficiency and toxicity. COREXIT products are the principle US dispersants. In 1967 EXXON produced COREXIT 7664. This weak-water based product was the first that was specifically formulated for the marine environment. This product was not used during the TORREY CANYON. In 1972 EXXON produced the first â€Å"selfmix† concentrate, COREXIT 9527. This was the first product that could be applied by aircraft. In 1992 EXXON developed COREXIT 9500, which was effective on heavy, weathered and emulsified oils. (Exxon-mobil, 2004) By the third generation of formulas, dispersants consisted of surfactant with little solvent. These were designed to be mixed with water. 2. 3 FUNCTION OF DISPERSANTS Dispersants reduce the interfacial tension between the oil and water and helps the creation of small oil droplets, which move into the water column facilitating quicker natural biological breakdown (biodegradation) and dispersion. By decreasing the size of the oil droplets, and dispersing the droplets in the water column, the oil surface area exposed to the water increases and natural breakdown of the oil is enhanced. Dispersants are used to minimise the environmental impact of an oil spill. Dispersants do not eliminate the problem of an oil spill but are intended as a means of reducing the overall environmental impact of an oil slick at sea. Dispersant use accelerates the weathering and biological breakdown of oil at sea and reduces the impact of oil on sensitive foreshore environments. Oil Spill Dispersants are also highly effective in reducing exposure of sea birds to oil as most sea birds are oiled by slicks on the surface of the sea or in near shore coastal habitats. Dispersed oil is less sticky than undispersed oil, therefore the adhesion and absorption onto surfaces and sediments of dispersed oil is greatly reduced compared with the original oil slick. 2. 4 CURRENT DISPERSANTS Over time, dispersants have developed over what one usually divides into three generations. The first generation of dispersants that came out on the market were hydrocarbon-based and were made of aromatic hydrocarbons, which gave rise to toxic effects. The second generation of dispersants that developed, the so-called ‘conventional dispersants’, contained no aromatic hydrocarbons and are used today in seas where they are applied directly from vessels without dilution. Conventional dispersants are starting to be replaced by the third generation of dispersants, the so-called ‘concentrated dispersants’ because these are easier to handle during clean-up operations. Concentrated dispersants are diluted with water before application, such that the volume problem on vessels and aircrafts decreases. Third generation dispersants are usually divided into two types based on their solvent agent – water-based or hydrocarbon-based. Hydrocarbon-based dispersants The solvent is a hydrocarbon with a low or no aromatic content. These dispersants typically contain between 15-25% surfactant and are intended for neat application to oil. They should not be pre-diluted with sea water since this renders them ineffective. They also require a high application rate of between 1:1 to 1:3 (dispersant to oil). Hydrocarbon-based dispersants are less effective and may be more toxic than concentrate dispersants and, as a consequence, in many countries are not now commonly in use. Concentrate or self-mix dispersants These dispersants contain a blend of different surfactants with both oxygenated and hydrocarbon solvents. They contain a higher concentration of surfactants (25% to 65%) and can be applied either undiluted (neat) or pre-diluted with sea water although it is more common to apply them undiluted. A typical dosage ranges between 1:5 to 1:30 (undiluted dispersant to oil). Water-based concentrated dispersants have a comparatively low toxicity, but require a longer time to disperse oil than ready-mixed products. Due to this time lag, there is a risk of using too much water-based dispersant before the process is complete. The hydrocarbon-based products have a higher toxicity than water-based products but require a lower dose with application. The manufacturers therefore claim that the toxicity levels of both types of products are low. A summary of dispersants used today is provided below (Table 1). Table 1. The table summarises the dispersants used today, application methods and dosages. Standard name| Generation| Type| Application method| Solvent| Dosage(dispersant/oil)| ConventionalDispersants| Second| 1| Not diluted on ships. | No aromatic hydrocarbons| 30-100%| Concentrated dispersants| Third| 2| Diluted on ships. | Water-based (e. g. glycol ether)| 5-15% (concentrated products)| | | 3| Not diluted on ships or airplanes. | Hydrocarbon based. | | The water-based dispersants’ solvent is made up of alcohol, glycols and glycol ethers (mostly ethanol, isopropane, ethylene glycol and propylene glycol) to increase its ability to mix with oil and lower the freezing point. Surfactants make up over 20% of these dispersants. The dispersant is applied from ships and diluted before application. Water-based dispersants require a relatively long time to complete dispersion. It has been argued that exceeding the dosage of these substances is common because people’s expectations for oil dispersion are too high. The most important limitation is their sensitivity for extreme temperatures. At high temperatures, there are security risks as certain solvents used in products are fire-hazardous. The most critical temperature area, though, is under 0 °C, because the risk for refreezing in the spreading device is high. The development of concentrated hydrocarbon-based dispersants, also known as self-mixing dispersants, has made the dispersion of oil on the sea surface much faster and easier. Self-mixing dispersants are spread from aircrafts, which means a doubling of the capacity. At present the following oil spill dispersants have been approved under the National Plan guidelines. Their Trade Names are listed below: * Tergo R-40 * Ardrox 6120 * BP-AB * Corexit 9500 * Corexit 9527 * Corexit 9550 * Shell VDC * Shell VDC+ * Slickgone NS * Slickgone LTSW. Composition of common dispersants Corexit 9527 The proprietary composition is not public, however the manufacturers own safety data sheet on Corexit EC9527A says the main components are 2-butoxyethanol and a proprietary organic sulfonate with a small concentration of propylene glycol. Corexit 9500 In response to public pressure, the EPA and Nalco released the list of the six ingredients in Corexit 9500, revealing constituents including sorbitan, butanedioic acid, and petroleum distillates. Corexit EC9500A is mainly comprised of hydrotreated light petroleum distillates, propylene glycol and a proprietary organic sulfonate. Environmentalists also pressured Nalco to reveal to the public what concentrations of each chemical are in the product; Nalco considers that information to be a trade secret, but has shared it with the EPA. Propylene glycol is a chemical commonly used as a solvent or moisturizer in pharmaceuticals and cosmetics, and is of relatively low toxicity. An organic sulfonate (or organic sulfonic acid salt) is a synthetic chemical detergent that acts as a surfactant to emulsify oil and allow its dispersion into water. The identity of the sulfonate used in both forms of Corexit was disclosed to the EPA in June 2010, as dioctyl sodium sulfosuccinate. Often referred to as docusate sodium, this chemical is the active ingredient in several stool-softener laxatives. Sorbitan (3S)-2-(1,2-Dihydroxyethyl)tetrahydrofuran-3,4-diol| | Sorbitan is a mixture of chemical compounds derived from the dehydration of sorbitol. The mixture can vary, but usually consists of 1,4-anhydrosorbitol, 1,5-anhydrosorbitol and 1,4,3,6-dianhydrosorbitol. Sorbitan is primarily used in the production of surfactants such as polysorbates. Sorbitan esters ( also known as Spans ) are lipophilic non ionic surfactants that are used as emulsifying agents in the preparation of emulsions, creams, and ointments for pharmaceutical and cosmetic use. When used alone they produce stable water-in-oil emulsions but they are frequently used with a polysorbate in varying proportions to produce water-in-oil or oil-in-water emulsions or creams with a variety of different textures and consistencies. Sorbitan esters are also used as emulsifiers and stabilisers in food. Toxicity The relative toxicity of Corexit and other dispersants are difficult to determine due to a scarcity of scientific data. The manufacturers safety data sheet states No toxicity studies have been conducted on this product, and later concludes The potential human hazard is: Low. According to the manufacturers website, workers applying Corexit should wear breathing protection and work in a ventilated area. Compared with 12 other dispersants listed by the EPA, Corexit 9500 and 9527 are either similarly toxic or 10 to 20 times more toxic. In another preliminary EPA study of eight different dispersants, Corexit 9500 was found to be less toxic to some marine life than other dispersants and to break down within weeks, rather than settling to the bottom of the ocean or collecting in the water. None of the eight products tested are without toxicity, according to an EPA administrator, and the ecological effect of mixing the dispersants with oil is unknown, as is the toxicity of the breakdown products of the dispersant. Corexit 9527, considered by the EPA to be an acute health hazard, is stated by its manufacturer to be potentially harmful to red blood cells, the kidneys and the liver, and may irritate eyes and skin. The chemical 2-butoxyethanol, found in Corexit 9527, was identified as having caused lasting health problems in workers involved in the cleanup of the Exxon Valdez oil spill. According to the Alaska Community Action on Toxics, the use of Corexit during the Exxon Valdez oil spill caused people respiratory, nervous system, liver, kidney and blood disorders. Like 9527, 9500 can cause haemolysis (rupture of blood cells) and may also cause internal bleeding. According to the EPA, Corexit is more toxic than dispersants made by several competitors and less effective in handling southern Louisiana crude. On May 20, 2010, the EPA ordered BP to look for less toxic alternatives to Corexit, and later ordered BP to stop spraying dispersants, but BP responded that it thought that Corexit was the best alternative and continued to spray it. Reportedly Corexit may be toxic to marine life and helps keep spilled oil submerged. There is concern that the quantities used in the Gulf will create unprecedented underwater damage to organisms. Nalco spokesman Charlie Pajor said that oil mixed with Corexit is more toxic to marine life, but less toxic to life along the shore and animals at the surface because the dispersant allows the oil to stay submerged below the surface of the water. Corexit 9500 causes oil to form into small droplets in the water; fish may be harmed when they eat these droplets. According to its Material safety data sheet, Corexit may also bio accumulate, remaining in the flesh and building up over time. Thus predators who eat smaller fish with the toxin in their systems may end up with much higher levels in their flesh. Effectiveness The oil film will be dispersed in small droplets which intermix with the seawater. The oil is then not only distributed in two dimensions (on the surface) but is dispersed in three (in the water). In handling Louisiana crude Corexit EC9500A (formerly called Corexit 9500) was 54. 7% effective, while Corexit EC9527A was 63. 4% effective. The EPA lists 12 other types of dispersants as being more effective in dealing with oil in a way that is safe for wildlife. One of those tested was Dispersit, which was 100% effective in dispersing Gulf oil and is less toxic to silverfish and shrimp than Corexit. Alternatives UK authorities have an approved list of products which must pass both sea/beach and rocky shore laboratory toxicity tests, following a review of approval procedures over a decade ago. Corexit did not pass the rocky shore test when submitted for renewal of its inclusion on the list, and was dropped. Although it has been omitted from the approved list since 1998, existing stocks which pre-date the removal may be permitted for use away from rocky shorelines, subject to prior approval. SLICKGONE NS Dasic Slickgone NS is one of the best selling Type 3 concentrate dispersants on the world market and has frequently been shown to be the most effective dispersant available for a wide range of different oils including those with a high wax content. Slickgone NS is extremely low in toxicity to marine organisms and is approved by many international approval organisations. SLICKGONE EW Dasic Slickgone EW is the latest member of the product range. Slickgone EW combines high efficiency and low toxicity with an exceptional ability to breakdown chocolate mousses (water in oil emulsions). Slickgone EW will continue to disperse efficiently those oils which have become too weathered to be amenable to conventional dispersants, therefore extending the window of opportunity for dispersant use. Unlike most dispersants, Slickgone EW is also effective on refined oils and bunker fuels making it a truly versatile dispersant for the 21st century. SLICKGONE LTSW Dasic Slickgone LTSW is a water based, hydrocarbon free, concentrate dispersant. It is highly effective at emulsifying crude oils, fuel oils and water in oil emulsions. It has extremely low toxicity and is internationally approved. CHAPTER 3 3. 1 MECHANISM OF DISPERSION Following an oil spill, some of the oil will disperse naturally into the water column. The extent to which this occurs depends on the type of oil spilt and the mixing energy. Oils with a lower viscosity are more amenable to natural dispersion than the ones with a higher viscosity. Natural dispersion takes place when the mixing energy provided by the waves and wind is sufficient to overcome surface tension at the oil/water interface and break the oil slick into droplets of variable sizes. The chemical dispersion process. A: Dispersant droplets containing surfactants are sprayed on to the oil. B: The solvent carries the surfactant into the oil. C: The surfactant molecules migrate to the oil/water interface and reduce surface tension, allowing D: small oil droplets to break away from the slick. E: The droplets disperse by turbulent mixing, leaving only sheen on the water surface. Generally, larger oil droplets will rapidly resurface and then coalesce to form an oil slick, but the smaller droplets will remain suspended in the water column where they will be diluted by turbulence and subsurface currents. The process of natural dispersion takes place in moderately rough seas with breaking waves and winds above 10 knots (5 m/s). Chemical dispersants aid the natural dispersion of oil by reducing the oil/water interfacial tension and, along with the natural motion of the sea, allow the break up of oil on the water into very fine droplets. Effectiveness of oil dispersion by chemical dispersants at sea is governed by a range of conditions and include the: * type and chemistry of the oil, * degree of weathering of the oil, * the thickness of the oil slick, type of dispersant, * droplet size and application ratio, * prevailing sea conditions (wave mixing energy), and * sea temperature and salinity Oil Spill Dispersant effectiveness varies greatly with oil type spilt and the degree of weathering of the oil. For example with increasing wind speed and wave action, the loss of light oil components increases. Evaporation becomes more significant, causing an increase in viscosity and density of th e remaining oil, and forming emulsions with water. The oil slick becomes thicker and heavier. It is generally accepted that for oils over 2000 cSt (Centistockes a measurement of the mobility of oil) viscosity, the effectiveness of oil dispersants decreases significantly. An oil that was easily dispersed may change quickly by wind and wave action into an oil which is not dispersable. To achieve an efficient dispersion, oil droplet size must be in the range of 1 ? m to 70 ? m with the most stable size being less than 45 ? m. Smaller droplets are better as they remain suspended in the water column where they will be diluted rapidly in the top few metres of the sea to below harmful concentrations. The increased surface area provided by the small droplets also enhances the opportunity for biodegradation of the oil. It is important to remember that dispersants are manufactured primarily for use in the marine environment. Their efficiency will be optimum in waters with a salinity of around 30-35 parts per thousand (ppt) but will decrease rapidly in waters with a salinity below 5-10 ppt, especially when pre-diluted. Similarly, efficiency is also affected when salinity rises above 35 ppt. In freshwater, dispersant effectiveness is dramatically reduced because the surfactants tend to travel through the oil layer into the water column instead of stabilising at the oil/water interface. Nevertheless, some dispersants have been specially formulated for use in freshwater. In a confined freshwater system, other factors also need to be considered, such as whether there is sufficient water depth or exchange of water to achieve adequate dilution. 3. 2 TOXICITY OF DISPERSANTS Knowledge on the toxicity of dispersants comes largely from laboratory studies. Only in a few cases have systematic studies been carried out on the toxicity of dispersants at a spill. No common standard method for testing the effectiveness of dispersants has been developed yet, other than certain oil companies’ and institutes that have developed their own tests. This has made it difficult to compare different products on the market and has also resulted in wide variances in quality among products on the market. The need remains to develop a testing system that is accepted by all countries and is used for the approval of products based on the requirements of each country. se tests to measure the effectiveness of dispersants. Test results of approved first generation dispersants showed them to be highly poisonous on test organisms. Toxicity values around 1 mg/L (measured as 48 h LC50, the concentration that kills 50% of test organisms within 48 hours of exposure) were registered for many adult marine invertebrates. Examples of products that showed such valu es include BP 1002, Slickgone, Gamlen, Essolvene and Finasol SC. The most harmful component in dispersants is the solvent, with very high aromatic concentrations. Second generation dispersants showed lower toxicity values, often between 1 000 – 10 000 mg/L (48 h LC50) in adult organisms. Examples of such products include BP 1100X, some Corexits and Finasol OSR-2. (Lehtinen, 1981). The United States Environmental Protection Agency (EPA) has conducted toxicity tests on several of the dispersants they allow. Tables 4 through 7 summarise the toxicity of four different dispersants Corexit 9500, Corexit 9527, Dispersit 1000 and JD-109. The tests studied the toxicity of dispersants alone, dispersants with oil, and oil alone. The toxicity tests were carried out on the minnow Menidia beryllina (96-hours test) and the crustacean Mysidopsis bahia (48-hours). (EPA, 2001). In summary, the studies suggest that a mixture of oil and dispersant give rise to a more toxic effect on aquatic organisms than oil and dispersants do alone. Analyses of dispersants alone showed that Corexit 9500 and 9527 are the least harmful for aquatic organisms. Dispersit 1000 and JD-109 showed similar toxicity levels as the oil products. 3. 3 ANALYSIS OF THE PROS AND CONS TO USING DISPERSANTS AT OIL SPILLS An account of the pros and cons for the use of dispersants to combat oil spills n the sea is presented in Table 2. From an environmental point of view, the best method to control oil is naturally to remove the oil from the water using mechanical methods. When these methods do not work or there are other reasons for not using them, chemical dispersion of oil can be an alternative. If the decision is made to use dispersants instead of m echanical combat methods, one should keep in mind that chemically dispersed oil reduces the chances for later mechanical clean-up. Dispersants can only be used within a limited time period. The window for using dispersants at an oil spill is short. In addition, applying dispersants is only possible during daylight hours when one can still see the extent of the oil. In certain situations, using dispersants to combat oil spills in seas can be preferred as mechanical control actions are not always successful. Chemical dispersion prevents the oil from emulsifying. The advantage of chemical control is that it decreases the damage oil can cause on birds and marine mammals. In addition, the number of incidents where the oil slick affects beaches will also be reduced or prevented. In the case of an oil slick moving towards the coast, strategic use of dispersants can disperse the oil vertically towards deeper waters instead of it moving along the water surface towards shallower and more productive areas by the coast. If the oil is not sufficiently dispersed, there is even a risk that drops coagulate again and build a new film of oil. It is therefore important for the amount of mixing energy to be high for effective dispersion. Table 2. Pros and cons for the use of dispersants at oil spills. Pros| Cons| The oil does not remain on the water surface * Often the method that produces the fastest results * Compared to other methods, dispersants are more effective in weather conditions that create fast mixing of water * Easy to apply * Prevents the oil from emulsifying * Grinds up the oil making natural decomposition easier * Seabirds and marine mammals can be saved * Prevents oil contamination of beaches| * Builds an oil cloud underwater and can product harmful effec ts for aquatic organisms that would otherwise not have been affected by the oil * Not always effective on all oil types * Limited window of time for use (relatively short) * Application is only possible when the oil slick is visible * Must be used where water masses are large for effective dilution * Mixing of oil and dispersants can be more toxic than each part individually * Few studies looking at long-term effects in the field * If the oil is not sufficiently dispersed, drops can coagulate again * Oil drops can settle * During beach clean-up, dispersants can increase the penetration of oil into the sedimentation * Few field studies on the effects of bioaccumulation| CHAPTER 4 4. 1 RECOMMENDATIONS FOR THE USE OF DISPERSANTS Based on the knowledge garnered on dispersants and their effects, one can recommend their use on Nigerian waters. This is based on the deciding factors for effective dispersion – water temperature, salinity, and amount of mixing energy. Before dispersants can be recommended at all, more studies need to be conducted looking at the spread and bioaccumulation of dispersants at sea and what effects they can give rise to. 4. 2 SUGGESTIONS FOR FUTURE ANALYSIS AND RESEARCHS Over the course of this research, gaps in current knowledge were identified. The main areas that need future research are the spread of dispersants and how dispersion products and dispersed oil bio-accumulate. The long-term effects of dispersants need to be studied. In order to adequately understand the effects of oil dispersants on aquatic systems, the following studies should be undertaken: †¢ Long-term effects of dispersed oils on aquatic organisms †¢ Bioaccumulation of dispersants and dispersed oil †¢ Is there a risk that dispersed oil may coagulate again? †¢ Analysis of the environmental effects of dispersants used on past oil spills †¢ Analysis of the use of sinkers, beach cleaning agents, etc. 4. 3 REFERENCES 1.

Ethical Leadership in the Master of Science Leadership...

Leaders make critical decisions between right, wrong, and the lesser of two evils every day. These decisions can affect the person making the decision, their employees, and goals of the organization. There are many readings that describe ethics and leadership, but ethical leadership is basically knowing your inner values and having the courage to steadfastly live by them for the purpose of the common good. Southwestern Colleges Master of Science in Leadership program has given me a firm understanding of how important ethical reasoning is and how it impacts, good and bad, an organization. My first artifact, LEAD505 Leadership and Ethics Assignment explains that theres a strong relationship between good leadership and ethics. Since†¦show more content†¦My second artifact, LEAD505 Ethical Decision Making Assignment is significant because it contributes towards understanding that I may never truly feel comfortable with a specific outcome of a tough ethical decision. Is it ever really ethical to move-forward with the mindset of the ends justifying the means? For example, during my leadership studies I was able to understand that President Truman was forced to make one of the most difficult decisions in human history; end World War II with a significant number of civilian casualties or to continue the war for an indeterminate amount of time. The result of the atomic bomb dropping was to facilitate a quicker end to the U.S.’s involvement with the war. It is clear that the number of U.S. casualties were decreased by this one decision, but not without cost in other areas. As our countrys leader, President Truman determined that the ends did justify the means in regards to dropping the atomic bomb. Although President Truman did not use deceit or lying in the dropping of the atomic bomb, it raises the question as to whether or not it is ethical to move-forward with the mindset of the ends justifying the means. Ultimately there is no clear-cut or right a nswer to this question; it is dependent on the person making the decision.

Oil Spill in the Gulf of Mexico-Free-Samples-Myassignmenthelp.com

Question: Discuss about the Problem with the oil spill in the Gulf of Mexico. What are the Ethical Issues involved? Answer: Introduction The environment of the global business in the 21st century is very complex. Ethical issues are found in all kinds of business companies irrespective their sizes. The business organisation develops ethics codes of conducts so that the employees of the organisation will follow them and act accordingly. The most important complex ethical issues faced by the business organisations are decision making, compliance governance and the diverse cultures. Ethical dilemmas Ethical dilemmas the identification of the ethical based course of action are the important concern of the business organisations to prepare a framework for the ethical decision making. The recognition of the ethical issue, getting the facts, evaluation of the alternative course of action is the most important activities of the business organisations before making a decision test its reliability. The focus of the ethical decision making follows a process that will protect the employees of the organisation and will ensure that the entire operations of the organisation are conducted in a fair just manner( Parker Evans, 2014). The ethical decision making also ensures that the values beliefs of the individual employees of the organisation are protected. Discrimination Discrimination in the male dominated environment of the organisation is ordinarily found. A new female employee faces difficulty and sometimes complains against the inappropriate behaviour of the male employees. In this context, the management of the business organisation plans to organise training on sensitivity. Sometimes the management plans to move the female employee to a different location so that she will not be treated differently. In fact treating the female employee of the organisation differently is treated as the discrimination based on unethical conduct. Utilitarian ethics always does good for the employees of the organisation and limits the harm of the employees. The moral rights of the employees of the organisation are respected and protected by the correct approach of the ethical standard. In the process of the decision making, the just approach of the decision maker creates equality among all the employees. The ethical decision making focuses on promoting employees of the organisation(Vitez, 2017). The ethical decision making promotes the organisation as a whole. The decision-making process of the organisation fails when the individual profit is considered. The lack of ethical decision making enhances individual benefits and these lead to the lawful liabilities for the organisation. The problem with the oil spill in the Gulf of Mexico. What are/were the ethical issues involved? The problem with the oil spill in the Gulf of Mexico is considered as one of the most important ethical dilemmas that have been faced by the petroleum industry in the current time. The oil spill happened in the year 2010 and it continued for three months(Rubia, 2010). The oil spill occurred due to the release of the gas followed by the explosion that caused eleven lives seventeen injuries. This caused a fearful impact on the environment and polluted the land seas. Ethical issues related to the oil spill The ethical issues related to the incident are related to the negligence of the management to take care of the safety issues in the Gulf coast and avoiding the warnings the problems raised by various reports. The reports also focus that the oil spill is due to the decline in the performance quality( Malik, 2010). The pleas of the employees related to the potential risks were neglected by the management of the organisation and the data on the risks were considered as the fake data. The entire situation reveals that there were safety issues and the ethical dilemmas are related to the huge failure of the maintaining the integrity of the system that was required to be maintained in the workplace of the organisation(ABERNETHY, 2010). Failures of BP The series of accidents brought a decline in the reputations of the company. The effects of the accidents on the environment the human rights have been proved unethical. In 2005, the accident in Texas City caused the death of the fifteen workers and 180 injuries. The investigation on the accident indicates that the cost cutting approach high production caused a decline in the safety regulations of the refinery. The company failed to clean the pipeline as per the law. The poor ethical decisions failure of the management by the executives of BP caused to pay a huge fine. The disaster could have been avoided by controlling offshore drilling. The company was required to prepare for the product disaster so that it would get the permission for the offshore operation. The company crafted poor plans and the plans were nonspecific and the plans were also based on the false information. Disaster in the Deepwater Horizon The faults in the internal external regulations and the failure of the philosophy of management to reduce to cost and taking risk brought the explosion in the Deepwater Horizon and that caused gas leak subsequently. The explosion on 20thof April, 2010 at BPs Deepwater Horizon oil rig, Gulf of Mexico caused the death of eleven workers. This created a huge oil spill five thousand below the surface and it had continued for eighty-seven days(Barron, 2012). It was the worst marine spill that spread around six hundred miles of the coastline. This caused the death of 1000s birds, fish marine animals. This invaded wetlands marshes. The estimation made on the loss indicated that around fifty-three thousand barrels of oil were leaked per day. Failure of Halliburton ,Transocean and MMS The responsibility of oil leak was also owned by Transocean that was given the charge of Deepwater Horizon(Colwell, 2014). Halliburton was given the responsibility of cementing the procedure. The failure of these two companies to perform their tasks was also one of the reasons for the oil spill. The attempts by the engineers for capping the leaks became successful on fifteenth of July and on September 19ththe well was sealed officially. With the joint efforts of BP, the Coast Guard, MMS the volunteers groups the entire containment cleanup were made. In Louisiana, Alabama, Mississippi Florida command posts of the incidents were created in order to oversee the containment of the offshore the response of the onshore. There were installations of the marine protection booms(Susskind, 2015). In order to stop the spread of the oil, ships aircraft were used. The company also trained people to help in the cleanup area and the programme was named as Vessels of Opportunity programme. Unethical management directives of BP The damage caused for the unethical management directive impacted on the organisation. The organisation wanted to control the information about the effects. The company issued press releases so that it can motivate people(Kroh Conathon, 2012).The company depicted that it supports to Transocean after drilling rig fire. The company through its press release wanted to prove that Transocean is responsible for the oil spill and now BP will help it to work for consolidating the situation. In other press releases, the company informed about the progress of the cleanup movement the grants of twenty-five million dollars to the coastal states(Safina, 2011). The company also made an unethical work by forcing the workers volunteers to sign the confidential clauses. Theories on the corporate responsibilities of Thomas Donaldson focus on three conditions that govern the fundamental international rights. These conditions are: The right that protects subject of extreme significance This should be subject to importance The burden of it is affordable economically. The ownership of the property right, right to enjoy use the natural resources the right to survival are the fundamental international rights that are violated by the oil spill at Deepwater Horizon. The spill brought huge loss to the marine life and caused eight thousand birds death and deform of the seafood. The fishing industry suffered a lot due to the collapse of commercial recreational fishing in the Gulf of Mexico. The tourism industry, restaurant owners were affected by the explosion(Juhasz, 2011). The duties of the states, individuals the multinational companies are to avoid depriving, protect from depriving assist the deprived.The duty of the corporations is to help the deprived. All the companies remain failed to protect from the deprivation. BP could do nothing to help the tourism sector and the fishing industry that faced huge loss due to the oil spill(Petrolia, 2015). The attempt of BP to aid the deprived was too late. BP and other related companies took many wrong decisions that violated the ethical responsibilities of the company. Conclusion The devastating explosion at Deepwater Horizon occurred due to the missteps taken by BP, Transocean, Halliburton the MMS. The companies neglected their responsibilities acted in an unethical way. The decision of the management of the company was poor and unethical. There was a need of reformation of the relationship between the oil industry the officials of the government. The conflict of interest within the organisation of MMS needed to be eliminated. The implementation of the new rules is required to be made in order to avoid such a disaster in the future days. The individual companies require following the regulations of safety risk-management so that it will prevent the society to face any harm in future. Bibliography Malik, S. (2010, 06 29).
