EFFECT OF HEAVY METAL ZINC CHLORIDE ON RED BLOOD CELLS OF AQUATIC LIFE.

A wide range of pollutants, either physical-chemical-biological and radiological have been observed in the aquatic biota due to urbanization – industrialization and new technological development. Heavy metals are traced in some areas in sufficient concentration and physico-chemical forms that might create pollution problems. The present study is based on the impact of Zinc chloride on marine organisms. The fish Labeo rohita is subjected to analytical grade Zinc chloride in fresh water at different concentration of 40, 50, 60 ppm and its effect on Red Blood Cells was noted. The adverse effect of heavy metals was noted on reticuloendothedial system and haematopoisis.
