dc.description.abstractToxicity of cypermethrin, a synthetic pyrethroid insecticide, was evaluated for the juveniles (8.5± 1.5 mm) of a freshwater fish, Poecilia reticulata (Peters) in relation to selected environmental variables such as temperature, hardness, pH and salinity. The LC50’s were found to change significantly with the change in temperature, hardness, pH and salinity of water. The juveniles were found more susceptible to cypermethrin at low water hardness (270±1 mg/l) and low water pH (5.4) as compared to other variables. Based on LC50’s the order of toxicity of cypermethrin to juveniles of Poecilia was observed as: pH (1.04-1.09 ppb) was too low as compared to harmless or safe concentrations (45.18-75.25 ppb) for the juveniles at selected environmental variablesen_US
