Environmental Pollution free essay sample

Additionally, it has been demonstrated that some earthworms are able to increase metal uptake by plants, thus increasing the metal availability, one of the main limitation of phototypesetting, thereby improving efficiency of petrifaction (Went et al. , 2004). The obtaining organisms studied in this work were deficit worms, are one of the major botheration agents in freshwater environments (Fisher et al. 1980). According to Cunningham (1999), difficult are small burrowing worms often about 2-5 CM long and roughly 1 mm in diameter when fully mature.By feeding its head down in muddy sediments, consuming sediments at depth and depositing undigested material at the sediment-water interface, they could lead to downward sediment migration. Such sediment could be recycled through the feeding zone many times before ultimate burial below the deepest feeding zone (Motifs et al. , 1999). Deficit has a major effect on exchange Of redo-sensitive species across the sediment? water interface y its metabolism on prevention of the establishment of an OIC layer at the top of the sediment (Inasmuch et al. They are looking for ways in which humans can live and prosper without harming the environmental for future generation.

(Sanchez and Agpaoa, 1997 181) â€Å"History† History says that even in the early years of this Century typhoid fever and other enteric diseases were major causes of death, with many epidemics traced-producing viruses and bacteria paratyphoid and salmonellosis. In the letter half of the 20th Century we are still dumping enormous amount of untreated human wasted into our water ways, as a result, shellfish has become a carrier of hepatitis aquatic borne viral diseases of unknown source have increased and water of many beaches have been declared unsafe. Raw human health, contributes to direct, disruption of the environment when discharged into ponds, lakes and water ways, nitrogen and phosphates from water increases the nutrients of the water this is turn results in the growth of vast number of minutes, aquatic plant’s principally algae and phytoplankton eventually the increase of the plants produce a conditions termed eutrophication. The ecological process of enrichment and aging of water bodies. (The White House, Nov. 1965) Air Pollution Air pollution come from four main sources transportation power generation industry, and waste incineration of these, the biggest contributor to air pollution transportation particularly motor vehicle, motor vehicle emit carbon monoxide, hydrocarbons. Nitrogen oxides, photochemical oxidants, industry release sulfur dioxide particulates, nitrogen oxide particulates nitrogen oxides, and photochemical oxidants. (Brennan, 2006) Page. 122 Water Pollution The pollution we dump into our water and to the land is as varied as those intruded into the atmosphere. There have been dramatic examples of what can happen when water is severely polluted by petroleum leakage. Solid Waste Pollution Another pollution problem that confronts, the Philippines, today is the accumulation of Solid Waste. These maybe refuse such as garbage’s, rebbish or trash and ashes or junks and other things man throws away anywhere. Dumped trashes. Lead Pollution Sources most causes of lead poisoning occur among children who eat chips of lead containing paint that of the ceilings and walls of deteriorated houses. Lead points are widely used for home interiors and in many city slums. Where buildings have been poorly kept, 15 percent to 20 percent of children between ages of one to five, show evidence of lead poisoning. Noise pollution Noise is an environmental pollutant which is the least known and the least publicized. It is any loud and unpleasant sound in a modern-day urban setting such metro manila. Noise is everywhere in our home offices factories, restaurant and trees. It has multiplied itself to such a degree that it produces discomfort annoyance and even conflict between passenger’s drivers who switch on their radios or stereos sets extremely loud. â€Å"Following suggestion on how we can control Air Pollution† 1. Traffic rules and regulations should be raised. 2. Fuel used in industry and motor vehicle should contain less sulfur and lead. 3. Toxic gases and other pollution in factories, power and industrial plants must be controlled by the used of devised likes precipitators, scrubbers, cyclones after burnes, absorber and etc. 4. Efficient incineration and sanity hand fill should be used as community refuse disposal method. 5. Ordinances on proper refuse collections and disposal should be strictly enforced and new regulation enacted if necessary. Device are presently being developed to remove the solid particle and undesirable gases from automobile exhausts and garbage’s result in unsanitary surrounding these things attacks disease carrying insects. III- Effects â€Å"Effects of Environmental Pollution† The important problem in air pollution is its effects upon health. 1. Pollution can cause or worsen bronchitis gastroenteritis and colitis, flu, tuberculosis and pneumonia the five leading killer disease of the Philippines not to mention asthma and other respiratory diseases. 2. General discomfort like eye-irritation, difficulty in breathing and increase are also brought about air pollution. 3. Mental performances of individuals can be dulled and their reaction showed making them more prone to accidents. 4. Pollution diminish working efficiency and productivity of workers and this effects the economy of the country and even of the World as a whole IV- Solution A. Control of Air Pollution There are three basics approaches to the control of air pollution preventive measures, such as changing the raw materials used industry or the ingredients of fuel, dispersal measured, such as raising the heights of smoke takes, and the collection measured such as designing equipment to trap pollutants before they escape into the atmosphere nearly all the highly industrialized countries, the World some from type of legislation to prevent and control air pollution. One difficulty is that pollutants may be carried by the wind from one country to other, often of distance of thousands of miles, the death of lakes in the United States. Acids produced in Poritain and France has cause damage in Sweden. In the United States control of air pollution is chiefly the responsibility of the states and local government all the states have air quality management programs which are patterned after Federal Laws. The basics federal law dealing, with air pollution is the clean air act of 1970. The act was last amended in 1990, under this law the Federal Environment Protection set standards for air quality the Agency also place limits on the amounts, of pollutant that could be given off by cars. Factories and other sources of pollutant’s the states and industries were expected to develop and carry our plants to meet this standards, some of the federal deadline could not be meet, and they were extended several times. â€Å"Pollution Environmental† Environmental Pollution is any discharge of material or energy, into water, land or air that causes or may cause acute (short term) or chronic (long term) detriment to the earth’s ecological balance or that lower the quality of life pollutant may cause primary damage, with direct identifiable impact on the environment, or secondary in the form of minor perturbations in the delicate balance of the biological food web that are detectable only over long time periods.
