Hazards of Toxic waste essays

Hazards of Toxic waste essays The macabre aftermath of the tragedy of Bhopal in India may not capture headlines today, but gruesome memories of it remain and nightmares continue to haunt the victims. Bhopal is a classic example of massive leakage of Methyl Isocyanate, but indiscriminate disposal of toxic wastes over a long period of time is bound to affect life. Bhopal illustrates the view that, however foolproof an installation or factory is against leakage and pollution, error is possible. Admittedly, man in his bid for industrialization and technological progress creates pollution and the threat of toxic-gas wastes. Toxicity is the price we pay for progress. Mans ingenuity and resourcefulness have helped him adopt measures to contain the problem created by toxic wastes, but pollution continues to be a universal problem. A test carried out in Bayertown in the U.S.A., some five miles away from the Limerick nuclear-power plant, provided the stunning news that the environment was radon-tainted. Radon is produced b y the radioactive breakdown of uranium. It can flow for miles underground and it has long been recognized as a health hazard. The gas disperses quickly outdoors, but indoors it can reach a deadly level of concentration. It is reported that there are other toxic air pollutants that pose a threat in the average home where they are produced by common household products and building materials. The discovery at Bayertown emphasizes the practical problems of disposing of toxic wastes. The ever-present danger of gaseous discharge from factories is underscored by a mishap in Basel, Switzerland. A huge cloud of fetid gas and smoke is said to have spread to neighboring France and West Germany. Exposure to toxic wastes can affect our health. Toxic wastes can affect man through marine organisms and fish. ...

Corporate Social Responsibility and Profit Essay

Corporate Social Responsibility and Profit - Essay Example This paper illustrates that followers of CSR on the other hand state that being socially responsible is more important because of the social contract, as well as the argument that CSR can actually increase profit. Others in favor of CSR say that it is already an obligation, and the issue is simply one of finding ways in which companies can act in ways that are socially responsible. Even companies who agree that CSR is important often have problems putting CSR principles into practice. The main critics of CSR claim that standards of living have greatly improved over the past 100 years and that this improvement is a result of â€Å"the success of free enterprise†. Critics of CSR attack those in favor of it by saying that profit is a needed and helpful advantage of business because it is this very profit which allows businesses to put funds into helping society. The reduction of profits gained by companies caused by CSR can actually have bad effects on society because lesser prof its mean less ability to help society. If companies spend more time paying for functions that make them socially responsible, they will not be able to focus on the profit which is important for shareholders. Without shareholders, the company does not exist, and so it cannot help society by giving it funds. Many people in favor of CSR say that many business ethics of big corporations are unethical, but critics reply by saying that it is unethical for managers to think of anything else than maximizing shareholder profits. Also, making companies responsible for many different aspects of society risks managers and directors being distracted. Critics also say that there is a big difference between taking account of society’s interests and being accountable for society’s interests; only the former element should be imposed on managers and businesses.

Economics term papaer Paper Example | Topics and Well Written Essays - 1000 words

Economics papaer - Term Paper Example It would help in tightening the liquidity of the economy. It can be depicted that when such reserves are made by the commercial banks with the Central Bank then it has an impact upon the balance sheet of both the banks i.e. the Central Bank and the commercial bank. At the outset, there will be rise in the Central Bank’s liabilities since the quantity of deposits that the commercial bank is supposed to keep with the Central Bank is rising by 0.5%. Conversely, the assets side of the commercial bank will be impacted. There will be rise in the assets side of the commercial banks. It can be treated as deposits at other banks, so in the balance sheet there will be rise in the deposits at other banks too. Question Two It can be stated that there are four basic components of the GDP. They are consumption, investment, government spending and value of exports and imports. The GDP of an economy is calculated by adding up the value of expenditures on the consumption, value of the expendit ures in investments, rate of the government procurement of goods and/or services, value of exports of the goods and the services minus the value of the imports of the goods and the services. ... All the three components of the GDP will be impacted. The reason behind this is that when the inflation is controlled then the rate of consumption will increase and thus the economy will be able to invest more. Thus, there will be rise in the consumption, along with rise in the investment and government spending. There will be rise in the exports as well. Effects on the Equilibrium and Aggregate Expenses It can be demonstrated that since the consumption will rise, it is quite obvious that there will be rise in the production as well. Therefore, the equilibrium real GDP will increase. Question Three The term ‘money multiplier’ can be figured out as the volume of money supply in relation to the volume of the base money. It is worthwhile mentioning that when the reserve deposit ratio or the cash deposit ratio is lower then, the money multiplier tends to be higher. The case of China is just the opposite. It can be demonstrated that when the economy plans to raise the reserve ratio requirement for the banks the money multiplier tends to shrink. Investment Multiplier It has been noticed that Central Bank planned to augment the rate of interest. If the rate of interest augments then more and more investors get attracted towards the bank. Although paying up of augmented interest rate is an increased cost for the Central Bank, but on the flip side, it can be viewed that the rise in the interest rate may tend to make it quite attractive for the international investors to purchase Renminbi and thus invest those Renminbi in China. With the rise in the interest rates, the income tends to rise thus forcing the consumers to invest in other sectors of the economy as well leading to growth in the overall economy (Bradsher, â€Å"China Move Could

Oil Extraction Essay Example for Free

Oil Extraction Essay When extracting lipids or fats from foods, both the method as well as the solvents chosen to perform a complete, or close to complete extraction are important. If these two elements are not taken into consideration, the extraction may not be complete, or the extract may contain a large quantity of undesired impurities. The natural fats and oil are mixtures of glycerides of fatty acids. Fats and oils are naturally occurring organic compounds which belong to a large group of water insoluble substances called lipids. Lipids are relatively non-polar molecules, they can be pulled out of a sample using relatively non-polar solvents. With a non-polar solvent, only non-polar molecules in the sample dissolve while polar ones do not. A solution to the problem of extracting trapped lipids is to use an extraction procedure such as the soxhlet that will help break up the polar barriers and allow the solvent to reach the non-polar compounds and extract them. In this experiment, soxhlet extraction was used. Soxhlet extraction is an extraction method that uses chemical solvents. Oils from the algae are extracted through repeated washing, or percolation, with an organic solvent such as hexane or petroleum ether, under reflux in a special glassware. Copra, dried kernel of the coconut, was the sample used. Often though, the sample must be ground and prepared prior to the extraction procedure in order to break up the cell membranes and other structures that would make extraction difficult. In this experiment, petroleum ether was used as the solvent due to its low boiling point, relatively non-toxic nature (when compared to chloroform or methanol), and of course because it is quite non-polar. When talking about ether, two kinds can be used in lipid extraction: anhydrous diethyl ether CH3CH2OCH2CH3 and petroleum ether, which is a mixture of pentane (CH3CH2CH2CH2CH3) and hexane (CH3CH2CH2CH2CH2CH3). Petroleum ether is more non-polar, cheaper and less flammable than diethyl ether. Due to its greater non-polarity, petroleum ether will yield a more specific extract than diethyl ether because it will only extract the most polar molecules. However, as petroleum ether may not be able to break apart some of the more polar shells surrounding some lipids and give a near complete lipid extraction, diethyl ether is usually used despite its higher flammability and cost.

The Importance of Light in A Streetcar Named Desire :: A Streetcar Named Desire Essays

This paper will discuss the use of light in the play, "A Streetcar Named Desire", by Tennessee Williams. Blanche’s relation to light is quite obvious because she tries to avoid bright light of any kind. Her reaction to light can be regarded as an attempt to hide her true nature as well as her vanishing beauty and youth. By hiding from the light, she tries to escape reality. She covers the naked light bulb with a Chinese paper lantern, saying, â€Å"I can’t stand a naked light bulb, any more than I can a rude remark or a vulgar action† (Sc.3 p. 2093). This remark shows that Blanche would rather hide behind polite phrases than accept truth and reality. The paper lantern is not very stable, though, and it can easily be destroyed, just like her illusions. In scene six, she takes Mitch home with her and says, â€Å"Let’s leave the lights off† (Sc.6 p. 2309). Blanche thinks of Mitch as a future husband, and therefore she does not want him to know her past or her true age, and the best way to hide her age is to stay out of bright light where he could possibly see her wrinkles and fading youth in her face. Later in that scene, Blanche tells Mitch about her husband Allan: â€Å"When I was sixteen, I made the discovery – love. All at once and much, much too completely. It was like you suddenly turned a blinding light on something that had always been half in shadow, that’s how it struck the world for me† (Sc. 6 p. 2113). In her past, light used to represent love, but now it represents something destructive for her. Allan’s suicide erases the light or love, and thus she now does not believe in it any longer and tries to escape from the light and therefore escape reality. When Mitch tears off the paper lantern in order to take a closer look at her in the bright light, â€Å"she utters a frightened gasp† (Sc. 9 p. 2125). Then she tells him, â€Å"I don’t want realism. I want magic! Yes, yes, magic! I try to give that to people. I misrepresent things to them. I don’t tell truth, I tell what ought to be truth.
