Water Pollution

Water Pollution
In the grammar of human life, water plays an important role amongmany others for drinking, cooking, washing and bathing. Inaddition, too much water needed to irrigate the fields, farm,industrial, and much more.

Human action within the fulfillment of their daily activities, may have accidentally menambahjumlah inorganic substances in water andcontaminate the water. For example, removal of detergent into thewaters may be detrimental to the organisms that exist in the waters. Fertilization land rice fields or fields with artificial fertilizers,and then went into the waters will cause the growth of aquatic plants that are not controlled, called eutrophication, or bloom.Some types of plants such as algae, water nails, and water hyacinth will flourish and cover the surface of the waters so thatsunlight does not penetrate to the bottom waters. As a result,plants that are under the surface can not photosynthesize, so the level of oxygen dissolved in the water to be reduced.

Other chemicals, like pesticides or DDT (dichlorine diphenyltrichloroethane), which is often used by farmers to eradicate pestplants also may be detrimental to plants and other organisms. If inthe aquatic ecosystem pollution or pesticide DDT, DDT flow willoccur
