ABSTRACT

 

Heavy metals and its compounds have severely affected the aquatic ecosystem and human health. They are naturally occurring substances which are present in the environment at low and tolerable levels. In large amount they prove to be hazardous. The study carried out in this paper is of heavy metal copper. Copper chloride is ingested by aquatic life and human beings through (drinking or eating) or inhalation (breathing). Working in or living near an industrial site increases the risk of exposure. The impact of toxic effect of copper chloride was experimentally studied in fish Labeo rohita. This metal affects reticulo endothedial system and hematopoiesis. They change osmotic resistance of erythrocytes. It has been found out that red and white blood cells at different stages of the pathological process are subjected to quantitative and qualitative changes, deformations, large scale destructions, cytoplasm (swelling, changes in granulation and degree of coloration, vacuolization etc.) and nucleus (changes in structure colour, partial or complete discoloration of nuclear matter, division, extrusion of nuclei etc.) In human beings also this effect is observed. Liver, kidney, heart, joints etc. are damaged. The liver and kidneys produce metallothioneins and cause toxicity which is hazardous to human life
