Pollution - Essay ExampleBy steps taken for eliminating toxic substances from production process and by diminishing production of ill materials population can safeguard the environment and homophile health. Different forms of befoulment Air pollution Air pollution can be caused when pollutants like carbon monoxide, hydrocarbons, oxides of sulphur and nitrogen and also materials like dust, smoke and compounds of run for are emitted directly into the atmosphere. Global warming is caused by greenhouse gases like carbon dioxide (49% to 55%), chlorofluorocarbons (14% to 25%), methane (12% to 18%), nitrous oxides and other gases (13% to 19%). Some natural sources of line of work pollution are volcanoes, woods fires, oceans, swamps, lakes, vegetative matter and insects (Faiz, Sinha, Walsh and Varma, 1990, p. 3). Other sources which are caused by human activities are fuel like coal and wood burning and most importantly transport which is a major contributor towards air pollution. al l told the pollutants get dispersed in the air and pollution is measured by the mass of the pollutants per volume of air. This depends on a number of factors like quantity of emission, altitude and atmospheric conditions. Rain cleans the air which gets rid of harmful materials, but these substances can react with oxides of sulphur and nitrogen to produce acids which may cause damage to buildings, forests and water system bodies. This is popularized as acid rain. Solar radiation can produce ozone which can disrupt the atmospheric equipoise near the ground. (Faiz, Sinha, Walsh and Varma, 1990, pp. 3-5) Air Pollution To reduce air pollution it is necessary to set the standard of ambient air quality. In US there are two sets of standards of air quality and they are immemorial and secondary. The primary standard of air quality is designed in the way to protect the health of human beings and for this purpose those people who are more easily affected by air pollution (viz. children and t he aged(a) people) are taken into consideration. Secondary standard of air quality is designed for general public welfare. This includes air pollution effect on s anele, water, crops, animals, climate, economy and human comfort (Faiz, Sinha, Walsh and Varma, 1990, p. 8). In 1970, Clean Air subprogram Amendments was enacted and it changed the structure of air pollution control in US. This Act was further amended in 1977 and it enforce restrictions on plants and factories in areas having clean air to avoid any damage to air quality. Public fretfulness about air pollution increased in the late 1980s and numerous bills were passed to improve the living air pollution regulatory measures and also to deal with new problems like acid rain and ball-shaped warming. (Bailey, 1998, pp.78, 79) Oil Pollution It was the Torrey Canyon incident in 1967 which awakened the public in regard to vegetable oil pollution. Since then the Oil Pollution Compensation has seen numerous changes. The incide nt caused the public to make loud protests against oil pollution. This led to development of international conventions to provide compensation to those who bear the cost of cleaning up or to those who face pollution damages from uninterrupted spill of hydrocarbon mineral oil from tankers. These international conventions were developed chthonian International Maritime Organisation. (Azab, Shorbagy and Ghais, 2005, p.3) In the Arabian Gulf, concentration of petroleum hydrocarbon (PH) average to about 26 ug/l of surface water and about 5 ug/kg of the bottom. As there will be continuous rise of production and transportation of oil, the concentration of PH in water will keep on growing especially in water areas where there is maximum flow of traffic.
