Detergents are common household products used for cleaning of domestic materials. The ‘after wash’ of the detergents are either drained into the aquatic environment such as ponds, lakes, rivers, streams, etc. or they find their way into the aquatic environment by natural sewage. Hence in the present study, the acute toxic and histopathological effects of a detergent, “Linear Alkyl Benzene Sulphonate” (LABS) on the gill of Puntius ticto (a teleost fish) were evaluated. For acute toxicity study, the fishes were exposed to LABS (Henko) in graded concentrations (20-28 mg/L, except 22 mg/L) for 24, 48, 72 and 96 hr duration. All 30 (100%) fishes were died in the Henko concentration of 28 mg/L at 24 hr, indicating that the acute toxicity of LABS is dose dependent. The LC50 of Henko was found to be 25.5 mg/L. For histopathological study, the fishes were exposed to 2 mg/L Henko for one month. The histopathological examination of Henko-treated fish gill revealed severe changes in the epithelial lining of gill arch, gill rakers and gill filaments, suggesting that the LABS may induce the abnormal cellular structure in gill.
