Acute Toxicity of Indo-Sulpin to a fresh water Gastropod Thira Lineate Changes in Rate of Respiration

Toxicity of sumithion to the fresh water field crab has been studied by Bhagya Laxmi and Ramamurti (1981), Aness (1975) and Verma et al., (1978) observed the toxicity of some organophosphate compounds. The oxygen consumption has been estimated by Alam and Lomte(1984) after exposing the gastropods. Viviparous bengalensis in zink sulphate Lowry, O. H.; Rosenbroughi, N. J.; Farr,A. L. and Randall, R. J. et. al. (1951, 1983) have observed the effects of carbaryl on oxygen consumption of the fish, Channa punctatus Chaudari.et.al. (1988) have observed rate of oxygen consumption. Considering the studies on pesticide pollution on the fresh water gastropod Thiara on the fresh water gastropod Thiara Lineata the present investigation has under taken with the view to understand the acute toxicity and the effect on the rate of oxygen consumption. Organophosphate compounds are now extensively use in place of organochloride compounds on account of their lesser residuals toxicity, but the prevention of aqutic animals' mortality remains an important object of water pollution research. Kaviraj and konar (1982) have studied the effects of heavy metals on accute toxicity of mercury, chromium and cadmium and cadmium to the fish. Tyllapia Mossambica. Mane and Akarte (1987) have studied the effects of cythion or Malathian on the estuarine Clam Catalasia optima.
