摘要：Discharged materials from the point or non-point source are released into the sea,and as the resuls,marine environment is directly affected. We must estimate the impacts of contarminants to marine pollution rapidly and accurately. Therefore,it is needed on early warming system for ppreciating marine environmental impacts,and required a bioassay to evaluate abnormal changes. A bioassay test was developed to examine the efets of heavy metal contaminants on the early life stuges of the marine annimals. We have studied the ffects of metals on early dewelopment of a sca urchin species,Strongylocentrotus intermedius. s. itermedius embryos were tested with six metals (Cu,Ag. Zn,Cd,Cr,Ni) and showed the highest sensitivity to Cu as well as the lowest sensitivity to Cd. The order of biological impact for metals was Cu> Ag> Ni> Zn> Cr> Cd. In accordance with the results,sea urchins embryos can provide biological criteria for seawaler quality assessment. The sensitivity of developmental bioassay whith S. intermedius is at intermediate level among marine organisms commonly used in aquatic biossays. And this sea urchin can be routinely employed as a test organism for ecotoxicity assays.
