Acute toxic effects of cadmium and copper to Pseudorasbora parva and copper to Daphnia magna were tested in this study. Then comparative analysis of species sensitivity of P. parva to six typical pollutants was performed with toxicity data from our experiments and published literatures. The result showed that: (1) P. parva was generally sensitive to various pollutants, especially to organic pollutants, and it was relatively most sensitive to pesticides. P. parva might be an indicator organism in organic pollution monitoring and a representative testing organism in the development of water quality criteria. (2) Cyprinidae was sensitive to various pollutants in fish sensitivity distribution, therefore the toxicity data of Cyprinidae should be given more attention in the study of water quality criteria and environmental monitoring. (3) P. parva was sensitive to various pollutants, and it had a stable position in fish sensitivity rank. This study indicated that P. parva might be an ideal indicator organism in environmental monitoring and a potential model organism in water quality criteria considering that it has a small size and is easy to obtain.
本研究测试了镉和铜对麦穗鱼的急性毒性效应以及铜对大型溞的急性毒性效应。然后，利用我们的实验数据和已发表文献中的毒性数据，对麦穗鱼对六种典型污染物的物种敏感性进行了比较分析。结果表明：（1）麦穗鱼对各种污染物总体上较为敏感，尤其是对有机污染物，且对农药相对最为敏感。麦穗鱼可能是有机污染监测中的指示生物，也是水质标准制定中的代表性测试生物。（2）鲤科鱼类在鱼类敏感性分布中对各种污染物敏感，因此在水质标准研究和环境监测中应更多关注鲤科鱼类的毒性数据。（3）麦穗鱼对各种污染物敏感，在鱼类敏感性排序中具有稳定的位置。本研究表明，考虑到麦穗鱼体型小且易于获取，它可能是环境监测中的理想指示生物和水质标准制定中的潜在模式生物。
