METAL INDUCED OXYGEN TENSION AND BEHAVIOURAL CHANGES IN FRESHWATER SNAIL BELLAMYA BENGALENSIS: COMPARATIVE STUDY

Dr. Kamble N. A.*

ABSTRACT

Heavy metals are major pollutants released into the environment. Comparative study of these metals against physiological alterations provides information about toxicity nature and biomonitoring mechanism. Present investigation deals with intoxication of zinc sulphate and lead acetate against respiratory mechanism and oxygen tension occurred in snail for pre-determined mean LC50 concentration 1.06 ppm for zinc sulphate and 0.77 ppm for lead acetate respectively, for different exposure period. Histological damage in to gills and rate of gas transportation, resulted to problem of oxygen scarcity. As a impact, snails under experiment changed normal behavior and tried to escape from toxic environment for their survivality. Lead acetate found to be more hazardous than zinc sulphate, as rate of oxygen consumption was drastically reduced with increased oxygen tension. Present investigation provides comparative metal toxicity and respiratory dysfunction and altered behavioral pattern in aquatic snail Bellamya bengalensis (L).
