ABSTRACT
To determine the acute toxicity of pesticide in freshwater ecosystem and its effect on hematological parameters of aquatic organisms, the short-term toxicity screening test and the bioassay experiments were performed using lindane, an organochlorine insecticide and potential toxic pollutant, and bagrid catfish (Pseudobagrus fulvidraco). The experiments were repeated in triplicates and the time-LCso values were determined at 24, 48, 72, and 96 hour, employing the static test method and the water temperature regulated at 23±1°C. The time-LCw values for bagrid catfish were estimated 38.83, 33.84, 30.30, and 28.43 fig/ f for 24, 48, 72, and 96 hour respectively. The hematological parameters, such as red blood cell count, hemoglobin concentration and hematocrit, were decreased with increasing exposure concentrations of lindane, maybe due to the disruptive action of lindane on the erythropoietic tissue.
