Dangers Of Water Pollution Essay

(a) Phosphorus and Nitrates from fertilizers and detergents contaminate sur­face waters where they act as nutrients and promote the growth of oxygen consuming algae which reduce the DO level of water, killing fish and other aquatic organisms.

(b) Industrial effluents result in the addition of poisonous chemicals such as Arsenic, Mercury, Cadmium, Lead etc., which kill aquatic organisms and may reach human body through contaminated food (i.e.

fishes etc.) (c) Domestic, commercial and industrial effluents (petroleum refineries, paper mills, breweries, tanneries, slaughter houses) contaminate the water with organic pollutants.

These provide nutrition for micro-organisms which decompose the organic matter and consume oxygen and reduce the DO level of the aquatic system thereby killing the aquatic organisms.

(d) Non biodegradable pesticides (especially organ chlorines) travel through food chains and ultimately reach humans where they accumulate in the fatty tissues and affect the nervous system.

(e) Waterborne infectious enteric diseases like typhoid, bacillary dysentery, cholera and amoebic dysentery are the predominant health hazards arising from drinking contaminated water.
