| 摘 要： | 对《我国淡水水生生物镉基准研究》一文推算的国家镉基准进行了修正，采用“重新计算法”推算了我国典型流域的镉生物基准，并以辽河上游的大伙房水库为试点，利用“水效应比值法”推算了区域镉基准. 结果表明:我国国家镉急性和慢性基准分别修正为1.81和0.21 μg/L；珠江流域、长江流域、太湖流域和辽河流域的镉急性基准分别为3.60，3.61，3.19和2.95 μg/L；镉慢性基准分别为1.39，0.06，0.04和0.04 μg/L；大伙房水库镉急性和慢性基准分别为2.72和0.05 μg/L. 流域及区域的镉急性基准值全部大于国家急性基准值，但大部分镉慢性基准都严于国家慢性基准.

| Abstract: | This study modified the national criteria for cadmium which were derived in the paper Development of Aquatic Life Criteria for Cadmium in China. The aquatic life criteria for cadmium for typical basins and the aquatic region criteria for cadmium for Dahuofang Reservoir, which is located upstream of the Liao River, were developed by the “recalculation procedure” and “water-effect ratio procedure,” respectively. The results showed that the modified national acute and chronic criteria were 1.81 and 0.21 μg/L, respectively. The acute criteria for cadmium for Zhujiang River basin, Changjiang River basin, Tai Lake basin, Liao River basin and Dahuofang Reservoir were 3.60, 3.61, 3.19, 2.95 and 2.72 μg/L, respectively, while the chronic criteria were 1.39, 0.06, 0.04, 0.04 and 0.05 μg/L, respectively. All the acute criteria of these basins and of Dahuofang Reservoir were greater than the national acute criteria, whereas most of the chronic criteria were more stringent than the national chronic criteria. |
