Abstract

The acute toxicity of dichlorvos (dimethyl 2, 2-dichlorovinyl phosphate) to freshwater snail (Pila ovata) was studied in toxicity bioassay. The test organisms were exposed to dichlorvos in a static renewal bioassay for 96hours. There was an initial range finding test to determine the concentrations of dichlorvos to be administered on the test organisms in the definite test. Five concentrations of the dichlorvos were prepared in the definitive test as 0.5, 1.0, 1.5, 2.0 and 2.5 ppm and a control experiment (0.0 ppm). The median lethal concentration (LC50) at 24hr, 48hr, 72hr and 96hr was 2.91, 1.74, 1.01 and 0.54ppm respectively. The median lethal time (LT50) at dichlorvos concentrations of 0.5ppm, 1.0ppm, 1.5ppm, 2.0ppm, 2.5ppm were 65.68hrs, 57.91hrs, 50.91hrs, 41.54hrs and 35.56hrs respectively. Mortality increased with increase in dichlorvos concentration and the number of survivors in each concentration differ significantly (p<0.05) from others. The present findings indicate that dichlorvos has mortality effect on Pila ovata and may adversely affect other aquatic organisms.
