出于比较目的，评估了镉、六价铬和铜对海洋鱼类幼虫（Cyprinodon variegatus）和桡足类（Tisbe battagliai）的毒性。对鱼类幼虫的毒性通过 7 天的存活和生长来衡量，而对桡足类的毒性则通过 8 天暴露后的存活和繁殖来评估。对于鱼幼虫，96 小时 LC(50) 值（基于总金属离子的平均测量浓度）为 1.23 毫克 Cd/升、31.6 毫克 Cr6+/升和 >0.22 毫克铜/升。 7 天后幼鱼存活和生长的亚慢性值 (SChV) 为 0.75 毫克镉/升、24.0 毫克 Cr6+/升和 0.16 毫克铜/升。对于桡足类无节幼体和成虫，96 h LC(50) 值如下。分别为 0.46 毫克镉/升和 0.34 毫克镉/升，分别为 1.60 毫克铬/升和 5.9 毫克铬6+/升；分别为 0.064 毫克铜/升和 0.088 毫克铜/升。 8 天后无节幼体存活和成虫存活或繁殖的 SChV 为 0.024 毫克 Cd/升、0.42 毫克 Cr6+/升和 0.008 毫克铜/升。
For comparative purposes, the toxicity of cadmium, hexavalent chromium and copper to marine fish larvae (Cyprinodon variegatus) and copepods (Tisbe battagliai) has been evaluated. Toxicity to fish larvae was measured in terms of survival and growth over 7 days, whilst toxicity to copepods was assessed in tel ms of survival and reproduction after 8 days exposure. For fish larvae, 96 h LC(50) values (based on mean measured concentrations of total metal ion) were 1.23 mg Cd/litre, 31.6 mg Cr6+/litre and >0.22 mg Cu/litre. Subchronic values (SChVs) for larval fish survival and growth after 7 days were 0.75 mg Cd/litre, 24.0 mg Cr6+/litre and 0.16 mg Cu/litre. For copepod nauplii and adults, 96 h LC(50) values were as follows. 0.46 mg Cd/litre and 0.34 mg Cd/litre, respectively, 1.60 Cr6+/litre, and 5.9 mg Cr6+/litre respectively; and 0.064 mg Cu/litre and 0.088 mg Cu/litre, respectively. SChVs foR naupliar survival and adult survival or reproduction after 8 days were 0.024 mg Cd/litre, 0.42 mg Cr6+/litre and 0.008 mg Cu/litre.
