Abstract
Forty eight hour (48h) static bioassays were conducted to determine the toxicity of Polysolve oil dispersant to Nile tilapia (Oreochromis niloticus) fry. Median lethal concentrations (LC50) were 1.03, 0.79, 0.70, 0.45, and 0.39% for 24, 30, 42, and 48h, respectively. Polysolve is highly toxic to Nile tilapia fry at low concentrations. Results showed increasing toxicity over increasing length of exposure. It is therefore recommended that Polysolve must not be used in oil spill response. Sublethal effects of the dispersant on the fry include decreased activity and impaired responses
