We conducted acute lethality tests with white sturgeon (Acipenser transmontanus) and Ceriodaphnia dubia exposed to copper and zinc at dissolved organic carbon concentrations ranging from 0.5 to 5.5 mg/L. Dissolved organic carbon had minimal effects on zinc toxicity but did have a protective effect on acute copper toxicity, which was equal to that predicted by the copper biotic ligand model (BLM). The BLM-adjusted copper median effect concentrations for A. transmontanus ranged from 2.4 to 8.2 mg/L. Environ Toxicol Chem 2019;38:2682-2687.

我们在溶解有机碳浓度为 0.5 至 5.5mg/L 的条件下，用白鲟（Acipenser transmontanus）和溞属（Ceriodaphnia dubia）进行了急性致死毒性试验，这些白鲟和溞属接触了铜和锌。溶解有机碳对锌毒性的影响很小，但对急性铜毒性有保护作用，其效果与铜生物配体模型（BLM）预测的相同。经 BLM 调整的铜对半致死效应浓度范围为 2.4 至 8.2mg/L。环境毒理化学 2019；38:2682-2687. 2019 年 Wiley 期刊出版公司代表 SETAC 出版。本文为美国政府工作，因此，在美国属于公有领域。
