Environmental Pollution
Article
Environmental pollution problem is an old problem facing mankind which until now the problem is still not resolved , even worse. Environmental pollution is the introduction of harmful substances into the environment so that environmental quality is reduced or does not function as intended. So the first order of environmental change due to environmental pollution . There are several factors that cause pollution are carried by humans , which is due to the ever increasing population growth and technological development . These factors also lead to the need to increase the population , for example, a growing number of users of private vehicles causing air pollution .
Pulotan is a term for human life , energy , substances or other components that cause pollution . There are three terms a substance said to be a pollutant , ie when the level or amount exceeds the normal threshold , are at the most inopportune times and are in a place undue .
Environmental pollution can be divided into several types , for example :
1 . Air pollution
Water is a basic human need . Water used for drinking , cooking and menuci . However , humans are not able to maintain the quality of water that is in the earth . It can be seen from the rampant water pollution news in the news like a pile of garbage at times or river . Water pollution can be caused by household waste , pesticides , fertilizers and inorganic waste .
Household wastewater known as domestic waste containing 95 % to 99 % water and the rest is organic waste . Household waste is a good food source for bacteria . When rivers and lakes contaminated with household waste , will be found the bacteria and can cause cholera and typhoid . As a result of the bacterial activity , a variety of other living things could die from lack of oxygen . Because at the time under aerobic conditions , spoilage bacteria use oxygen in the water to decompose organic matter . Most wastewater consists of nitrogen components , such as urean and uric acid which breaks down into ammonia and nitrite . Usually waters through which household waste algae population will increase rapidly due to the large supply of nutrients and oxygen in these waters persediaaan akaan reduced . The further downstream or in the direction of the estuary , more decomposed organic waste perfectly so that the oxygen content in the water returned to normal limits .
Organic waste is also a cause of water pollution . There are some industries that throw their waste into the river . These wastes containing toxic metals are like mercury , copper , cadmium , and zinc . Fertilizers and pesticides also cause water pollution . Fertilizers that are not absorbed by the plants can be carried by rain water , rivers or lakes into rivers or lakes that become rich nutrients and water hyacinth growth increased rapidly . Petisida a toxic chemical compounds used by humans to control pests . Pesticides containing herbicides , fungicides and insecticides are also not good for living things .
