HEAVY METALS POLLUTION IN WATER
Generally the water pollution is described as the presence in water of enough harmful or objectionable material to damage the water’s quality.
Water pollution has many sources and characteristics. Humans and other organisms produce bodily wastes which enter rivers, lakes, oceans and other surface waters; Industry is creating new chemicals each year, all of which eventually find their way to water. In high concentrations these wastes result in bacterial contamination and excessive nutrient loading (eutrophication). Inorganic industrial wastes are much tricker to control and potentially more hazardous Industries discharge a variety of toxic compounds and heavy metals, and wastewater from industrial process may also be too hot or too low in dissolved oxygen to support life.
