| Abstract: | Objective] The purpose was to discuss the acute toxicity effect of racemate of Peng-3 and its enantiomer on Daphina magna.Method] The standard experiment animals Daphina magna was used to study the acute toxicity effect of O,O-dimethyl-1-(phenoxyacetoxy) ethylphosphonate on Daphina magna.Result]The results showed that 48 h-LC50 of Rac-Peng3,Peng-3 pk1and Peng-3 pk2 for Daphnia magna were 0.274 1,0.368 5 and 0.262 3 mg/L,respectively.They were all high toxicity,but the difference of toxicity among them was not distinct.Conclusion]This study will provide the scientific reference for the research on harm of aquatic organisms. |
