Studies on the toxicity of Alkylbenzene sulphonate to Zebra fish, Danio rerio Hamilton

Abstract

Detergents are common household products used for cleaning of domestic materials. The ‘after wash’ of the detergents are either drained in to the aquatic environment such as ponds, lakes, rivers and streams or they find their way in to the aquatic environment by natural sewage. In the present study, the acute toxic effect of a detergent “Alkylbenzene sulphonate” (ABS) on Danio rerio was evaluated. For acute toxicity study, the fishes were exposed to different ABS concentrations (22, 24, 26, 28, 30, 32, 34, 36, 38 mg/l) for 12, 24, 48, 60, 72, 84 and 96hrs duration. The LC50 values of the prepared concentration for 12, 24, 36, 48, 60, 72, 84 and 96 hrs were 36.427, 32.506, 32.681, 31.717, 29.675, 29.506, 28.225 and 27.310 respectively.
