Popis:	The toxicity of Fenvalerate, O‐cyano‐3‐phenoxybenzyl‐2‐(4‐chlorophenyl)‐3‐methyl‐butyrate, Niclosamide, 2,5‐dichloro‐4‐nitrosalicylanilide and Profenofos, O‐4‐bromo‐2‐chlorophenyl‐O‐ethyl S‐propyl phosphorothioate, to Nile Tilapia fish were determined. The toxicity of some of the binary mixtures of Fenvalerate and Niclosamide when mixed with Ariel, the domestic detergent was assessed. Gill uptake of Fenvalerate was studied over various spans of exposure intervals, and compared to uptake level when detergent was added. The role of adding the detergent to enhance Fenvalerate penetration through gills was ascertained. Meanwhile, detailed studies on the relationship between detergent increase and Fenvalerate penetration was undertaken. Results indicated that Fenvalerate is the most toxic to Nile Tilapia with an LC50 of 0.015mgL−1, followed by Niclosamide, with an LC50 of 0.3mgL−1, while Profenfos was the least toxic, with an LC50 of 2.02mgL−1. The addition of detergent concentrations has increased the toxic e...
