The invention discloses a method for predicting and evaluating
toxicity of a novel non-
steroid anti-inflammatory agent
pollutant based on
daphnia magna. According to the method,
daphnia magna is exposed to the novel non-
steroid anti-inflammatory agent
pollutant with equal logarithm spacing concentration, the survival rates of
daphnia magna generated when the
daphnia magna is exposed for 24 h, 48 h and 72 h, and the
survival rate, the body length, the total number of shelling and egg carrying times and the total
daphnia magna producing amount of the
daphnia magna exposed for 21 d are recorded respectively; corresponding 24 h LC50, 48 h LC50 and 72 h LC50 are obtained through calculation of SPSS
software and used for evaluating
acute toxicity, and corresponding 21 d LC50, body length EC50, shelling EC50, egg carrying EC 50 and daphnia magna producing EC50 are obtained and used for evaluating chronic
toxicity; thus, the
toxicity characteristic and the toxicity level of the novel non-
steroid anti-inflammatory agent
pollutant are analyzed, tested and quantitatively described, meanwhile can serve as indexes for monitoring and evaluating biotoxicity of non-steroid anti-inflammatory agent
sewage, and can provide reference for predicting and evaluating potential
ecotoxicity risks of the pollutant in water.
