This study was undertaken to know the toxicity, distribution of sodium linear alkylbenzenesulfonate (LAS) and the histological feature of fish exposed to LAS or LAS-gluten solution. In LAS-gluten solution the apparent acute toxicity of LAS to fish was decreased. In distribution study using 14C-labeled LAS, it was found that in LAS solution the radio-activities were observed mainly in skin and gill, and in LAS-gluten solution the activities in these parts of fish were lower. But the radio activity in bile was higher in LAS-gluten solution than in LAS solution. Radio activity in whole body of fish was lower in LAS-gluten solution than in LAS solution. Histological investigation showed that gill and intestine and then kidney and liver were affected. Those histological effects of each organ occurred more faster in LAS solution than in LAS-gluten solution. The radio-active substance in the bile was detected as a metabolic product of LAS by TLC method.
