Abstract

EVALUTION OF ACUTE AND CHRONIC TOXICITY OF HEAVY METAL MERCURIC CHLORIDE TO A FRESHWATER GASTROPOD SNAILS, BELLAMYA BENGALENSIS (LAMARCK)

P. R. Mahajan*

ABSTRACT

Acute toxicity testing on freshwater Gastropod Snails, Bellamya bengalensis (Lamarck) to HgCl2 was carried out.
The Median Lethal Concentration (LC50) of HgCl2 for 24, 48 , 72 and 96 hrs were 3.934,2.390,1.380 and 1.099
ppm respectively.The Lethal concentration (LC10) of HgCl2 for 24,48,72 and 96 hours were 2.959,1.969,0.990 and
0.524ppm respectively. The safe concentration of HgCl2 to fresh water gastropod snails, B.bengalensis was
0.2551ppm.Anylysis of results indicates that B.bengalensis is highly sensitive to HgCl2.
