Some of the effects of water pollution are as: 1-Drinking polluted water can cause diseases like cholera,typhoid, etc. 2-Polluted water not only affects humans but the enviroment as well.Marine life is badly affected by polluted water.Marine species swallow toxic materials present in the water,which results in their death. 3-Oil spills in the ocean can block oxygen from dissolving into the water,causing marine life to suffocate.Oil spills are equally harmful to seabirds.Oil penetrates the waterproof layer of a bird's feathers.which affects its ability to stay warm and results in its death.
Water Pollution is the contamination of water bodies. It occurs as a result of introduction of pollutants in water. Water is life. Still, we contribute in polluting the water bodies in several ways.
Water Pollution is mainly caused as a result of improper discharge of household and industrial chemicals wastes into the water bodies.
These dangerous chemicals (in the form of solid, liquid or gases) mixes with water and make it unsafe for living bodies. Water pollutants cause harm to human-beings, animals, trees and other constituents of environment.
The sources, effects, and control measures of Water Pollution are discussed below.
Sources
The Sources of water pollution are:
Industry: Effluents from the factories.
Sewage: From human excreta to liquids of house hold works, drain water containing feces, urine and other pollutants.
Physical Pollution: heat and ionic radiation.
Different household activities.
Agriculture: Different chemical fertilizers, fungicides, pesticides used in agricultural field are washed out rain water and pollute by the different water bodies.
Minerals: Minerals above a certain level in the soil or present in the rocks, mix with water and results in pollution.
Effect of water pollution on human health
Presence of toxic metals in water may cause skin disease, dysentery, amoebiasis, anorexia, etc.
Radioactive substances present in water may lead to radioactive pollution causing cancer.
In polluted water the different water borne virus, bacteria, and protozoa are present. They cause small diseases likely pox, chicken pox, dysentery, amoebiasis, tuberculosis etc.
