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、0.123 μg/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8.700 μg/L,基准连续浓度为0.123 μg/L.
通過查閱數據庫,研究瞭重金屬鎘對我國淡水水生生物的毒性效應.在藉鑒美國環境保護跼提齣的毒性百分數排序法的基礎上,結閤我國的生物區繫特點和實際情況,計算齣瞭淡水中鎘的最終急性值、最終慢性值和最終殘留值,分彆為17.400、1.036、0.123 μg/L,併在此基礎上,得齣瞭淡水鎘的基準值,即基準最大濃度為8.700 μg/L,基準連續濃度為0.123 μg/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 8.700 μg/L and criteria continuous concentration was 0.123 μg/L.
