WU Yong-gui1,2,Xiong Yan1,LIN Chu-xia2(1.College of Resources and Environmental Engineering,Guizhou University,Guiyang 550003;2.College of Resources and Environment,South China Agricultural University,Guangzhou 510642).  
The study on the effects of the different levels of phosphorus on heavy metal(Cu2+,Zn2+ and Cd2+) joint-biotoxicity by the phototactic behavior of Daphnia carinata.The results showed that the biotoxicities of phosphates were very low in eutrophication waters.The different forms of phosphorus had different inhibition on Daphnia 's phototaxis in the sequence when their concentration was high: PO43-H2PO4-≈ HPO42-.The toxicity of heavy metals was influenced significantly by the levels of phosphorus coexisted.The phosphates would decrease the biotoxicities of Cu,Zn and Cd in waters,and thus somewhat decrease the harm of heavy metals to aquatic organisms.It indicated that heavy metal biotoxicity was correlated not only with themselves but also with the levels of phosphorus in eutrophication waters.So,the toxicity of heavy metal was higher with lower phosphate concentration,vice versa.It is thus necessary to point out that phosphorous and heavy metals should be decreased simultaneously in tackling water pollution.Otherwise,more serious environment disaster could be produced in water tackling by reducing the discharge of phosphorus in the case of heavy metal presence,even though the concentrations of heavy metals were lower in dystrophication waters.Suitable amount of phosphorus could be beneficial to decrease the biotoxicity of heavy metals.
