摘要
通过查阅数据库,研究了重金属镉对我国淡水水生生物的毒性效应。在借鉴美国环境保护局提出的毒性百分数排序法的基础上,结合我国的生物区系特点和实际情况,计算出了淡水中镉的最终急性值、最终慢性值和最终残留值,分别为17.400、1.036、0.123μg/L,并在此基础上,得出了淡水镉的基准值,即基准最大浓度为8.700μg/L,基准连续浓度为0.123μg/L。
Through referring to database, the toxicity effect of cadmium to our country＇ s freshwater aquatic organisms was studied. Based on the toxicity percentile rank method which was put forward by U.S. Environmental Protection Agency, and considering our country＇s aquatic biota characteristic and reality, the freshwater Final Acute Value, Final Chronic Value and Final Residue Value of cadmium were calculated, they were 17. 400, 1.036 and 0. 123 μg/L, respectively. Finally, the reference value of cadmium in fresh water was calculated, namely： criteria maximum concentration was 8. 700μg/L and criteria continuous concentration was 0. 123 μg/L.
