| Abstract: | We used fresh and brackish water shrimp (Desmoscaris trispinosa and Palaemonetes africanus), in sediment bioassays to assess the toxicity of an industrial detergent containing high levels of anionic surfactant (linear alkylbenzene sulphonate (LAS)). The Organization for Economic Cooperation and Development (OECD), # 218 direct sediment toxicity assessment was employed. The organisms were exposed to different concentrations (31.25, 62.5, 125, 250 and 500 mg/kg) of the chemical (Neatex) in replicate treatment... |
