Acute Toxicity and Behavioural Responses of Oligochaete Worm Tubifex tubifex Exposed to Pesticide Cartap Hydrochloride
Abstract: The present study was conducted to evaluate the acute toxicity in terms of 96h LC50 and behavioural responses of oligochaete worm Tubifex tubifex upon exposure to a thiocarbamate insecticide cartap hydrochloride. All experiments were conducted in a static bioassay system using increasing concentrations of insecticide for different exposure periods. The 24, 48, 72 and 96 h LC50 values of cartap hydrochloride to Tubifex tubifex were 0.045, 0.039, 0.023 and 0.0178 …
