| 摘 要： | 通过水生生物毒性试验，用多元回归分析方法，研究了乐安江沉积物中重金属铜等对大型蚤的毒性与其形态的关系，试验结果表明，重金属的生物可给态对大型蚤的毒性最大，间接可给定态次之，惰性态降低了其有害形态对蚤类的毒性。

| Abstract: | In this paper,with the use of multivariate regression analysis,the relations between the acute toxicites of Coppeer,Lead and Zine on Daphnia and their morphologies have been studied in the sediments of Le'an River by the acute toxicity tests on hydrobios.The results show that the organic morphology of heavy metals produce the most serious toxicity on Daphnia,the buffer morphology produces less serious toxicity and the inactive morphology decreases the toxicity made by other harmful morphorogies. |
