Effects of Lambda cyhalothrin on some electrolytes and metabolites in organs of Parpohiocephalus obscurus
The effect of Lambda cyhalothrin on some electrolytes and metabolites in some organs of Parpohiocephalus obscurus was investigated. The fish samples was purchased from private fish farm in Yenagoa metropolis and transported to the Department of Biological Sciences laboratory, Niger Delta University, Wilberforce Island, Bayelsa State, Nigeria where the study was conducted. The fish samples have mean weight and length of 42.20±0.1gSD and 16.50±0.12cmSD respectively. Various concentrations of the toxicants viz: 0.000, 0.012, 0.024 and 0.036ppm were made and the fish was exposed for 2 weeks in a renewal assay. At the end of the experiment, the fish were dissected and the muscle, kidney and liver obtained. The various parts were processed and analyzed using standard methods. The various parameters (viz: urea and creatinine in muscle and kidney and electrolytes including sodium in muscle and liver and only potassium in liver) showed significant variation (P<0.05) at various concentration of the toxicants. This is an indication of alteration of urea, creatinine, potassium and sodium of Parpohiocephalus obscurus exposed to Lambda cyhalothrin. In conclusion, electrolytes (sodium and potassium) and metabolites (urea and creatinine) are essential parameter in assessing toxicity of Lambda cyhalothrin in aquatic ecosystem.
