ACUTE TOXICITY OF HEAVY METALS (CADMIUM CHLORIDE (CDCL2) AND MERCURIC CHLORIDE (HGCL2) ON FRESH WATER BIVALVE LAMELLIDENS MARGINALIS FROM PRAVARASANGAM OF GODAVARI RIVER, MS. INDIA

ABSTRACT

The Bio-filter potential of the freshwater bivalve, Lamellidens marginalis was examined in experiments, collected from Pravara-Sangam of Godavari River. Bivalves are known for their low susceptibility to heavy metal toxicity. Since toxicity is based on the effect and toxicant produces at a target site in the body of organism. Establishment of relationship between the concentration of substance at target site of animal and the subsequent toxic effect which may can provide tools for predicting toxicity. Cadmium and Mercury are the major contaminants found in the river. The behaviour of single toxicant could not be fully understood without the knowing the fact of physical and biochemical properties of the substance that can change. To understand this, the acute toxicity of Cadmium chloride (CdCl2) and Mercuric chloride (HgCl2) on L. marginalis was determined. LC50 of CdCl2 and HgCl2 at 96 hr were noticed at 12 and 6 ppm respectively. More protein depletion observed in the digestive gland than gills and foot. The present research work served as an experimental tool and bio-indicators for the first line evaluation of environmental pollution.
