Different Types of Environmental Pollution

Thursday, January 13th, 2011

People always think that the water and air on the earth is endless, so they keep emitting million tons of waste gases into the sky and dumping numerous garbage into the rivers, lakes and oceans. As a result, human activities cause different types of environmental pollution. The clean-up of the garbage has become an important issue in many big cities. Among the million tons of garbage every day, most can not be incinerated or decayed, such as plastics, rubber and glass, which are considered as the number one enemy of mankind.
Marine pollution is mainly caused by the crude oil leaked from oil tanker and oil well, the pesticides and fertilizers used in agriculture, the sewage discharged from factories, and the acid solution exhausted from oil field. These wastes make most of the oceans and lakes polluted. As a result, not only the marine organisms are affected, but both the birds and humans may also be poisoned because of eating these organisms. Air pollution is the most direct and serious environmental pollution, mainly from the carbon monoxide and hydrogen sulfide emitted from factories, cars, power plants, and so on. Every day, there are many people infected with respiratory organ or visual organ diseases due to the exposure to these polluted air.

Water pollution happens when certain substance enters into the water and changes the chemical, physical, biological characteristics of the water, which then affects the efficient use of water, endangers human health, causes harm on the environment, and leads to the deterioration of water quality. Air pollution means that the concentration of pollutants in the air reaches to or above the hazardous level, which leads to the damage to ecosystems and the normal survival and development of human life. As a result, it will bring harms both on human being and creatures. Noise pollution is the phenomenon when the environmental noise exceeds the national emission standards of environmental noise, and interferences with the normal work, study, and living of other people.

Reasons for Water Pollution

Wednesday, February 3rd, 2010

Water pollution is the contamination or adulteration of the water bodies, such as rivers, lakes, seas, oceans, and ground water by number of human activities. Since water is essential for all our basic needs, water pollution is a threat to us. Many communicable diseases spread through unclean water, which even results in death.

Although there are different factors that contribute to water pollution, listed below are the most dangerous causes of water pollution. Factories and nuclear plants play a major role in polluting the water. Wastes from factories include toxins, such as lead, mercury, and other contaminants. These chemicals are very harmful and can lead to serious health hazards.

Nonpoint sources are one of the major causes of water pollution. Oil spills from cars, trucks, and other vehicles on land get mixed with rainwater and runoff into streams and lakes polluting them. These nonpoint sources are very difficult to monitor and control, so it falls on each individual to make sure that their vehicles used does not in any way contribute to further pollution. Proper maintenance of vehicles and oil spill cleanup using eco-friendly products, such as Oil Gone Easy S-200 will help to a great extent.

Fertilizers and pesticides used in agricultural farms, homeowners lawns, and roadsides are a threat to the natural water source. When runoff into local streams or rivers or when drained down into groundwater, they contaminate the water completely. Mining is another major reason for water pollution. Heavy metals and sulfur components which are buried in the earth are exposed during mining and during rainfall these toxic chemicals are exposed, which ultimately result in “acid rain drainage”. Surprising though it may seem, air pollution is also a cause of water pollution. Pollutants, such as sulfur dioxide, nitric acid, and mercury, when deposited out of air results in nutrient pollution and acidification of lakes.
