Abstract :
According to species sensitivity distributions (SSD) theory, selecte the aquatic species existing widely in Weihe River and collect their toxicity data, a new SSD model: the natural logarithms-cumulative probability model distributing (Ln-Normal) was developed for Phthalol(DEP), Dibutylphthalate(DBP), and Bisphenol A(BPA).Based on their SSD curves, the hazardous concentration for 5% of the species (HC5) were gotten. And then the criteria maximum concentration (CMC) and criteria continuous concentration (CCC) of DEP, DBP, BPA were 2150.5ug/L, 430.1ug/L; 10.92ug/L, 2.18ug/L and 485ug/L, 97ug/L, respectively.
