Evaluation of acute toxicity of carbaryl and malathion to fresh water teleosts channa punctatus and heteropneustes fossilis


, : Evaluation of acute toxicity of carbaryl and malathion to fresh water teleosts channa punctatus and heteropneustes fossilis. Toxicology Letters (Shannon) 20(3): 271-276

Bioassay tests evaluated the acute toxicity of carbaryl (a carbamate insecticide) (50% wettable powder, WP), and malathion (50% EC) (an organophosphate insecticide) (50% emulsifiable concentrate; EC) by determining their LC50 and the acute toxic ranges for 24, 48 and 72 and 96 h exposure to C. punctatus and H. fossilis. Regression equations and slope functions were determined for different time periods. The relative susceptibility of the fish, the relative toxicity and the safe concentrations of these biocides were calculated on the basis of LC50 for 96 h. C. punctatus was relatively more susceptible to both compounds, while malathion was the more toxic of the 2 biocides.
