Description
Summary:Permethrin, a synthetic pyrethroid pesticide and potential toxic pollutant contaminating aquatic ecosystems, was investigated in the present study for acute toxicity. Guppy fish ( Poecilia reticulata) were selected for the bioassay experiments. The experiments were repeated 3 times and the 48-h LC 50 was determined for the guppies. The static test method of acute toxicity test was used. Water temperature was regulated at 20 ± 1 °C. In addition, behavioral changes at each permethrin concentration were observed for the individual fish. Data obtained from the permethrin acute toxicity tests were evaluated using the probit analysis statistical method. The 48-h LC 50 value for guppy was estimated as 245.7 μg/l. Values in the range of 0.05–97.0 μg/l have been reported for various other fish species.
