| 摘要: |
| 个体、种群、群落、生态系统是水生态毒理研究的4个层次，实验系统的复杂性也按此顺序增加，本研究总结了这4个层次的毒性评价方法，无疑，高层次的研究结果准确性更高，但若在较低层次即便是在个体水平上能证实污染物的安全性，就没有必要再做更多工作。根据这些年的研究，由于污染物的亚致死影响越来越普遍，故有毒影响的可恢复性及恢复速度在危险性评价中就显得更为重要。另外一点是必须关注污染物间因相互作用对毒性效应及其恢复的影响。最后由于实验室条件与田间实际情况存在差异，故所有实验结果都必须经实际检验。 |

| Abstract: |
| Individual,population,community and ecosystem are 4 successive levels in aquatic ecotoxicological study,and in this order the experimental complexity increases.Toxicity evaluation methods adopted at each level were reviewed in this paper.It is no doubt that the extrapolated results are more accurate at higher experimental level.However,if a contaminant proves to be safe even at individual level,then it is of no need to do any more work.Summarized from the studies all these years,recoverability and recovery rate of the toxic effect are more important in risk evaluation as the sublethal effect becomes more popular.Also,the interaction among different contaminants on toxicity as well as recovery needs to be observed.As a last step,all the experimental results should be carefully detected in field situation for the difference between experimental conditions and the actual outdoors. |
