The absence of chronic toxicity data for tropical marine waters has limited our ability to derive appropriate water quality guideline values for metals in tropical regions. To aid environmental management, temperate data are usually extrapolated to other climatic (e.g., tropical) regions. However, differences in climate, water chemistry, and endemic biota between temperate and tropical systems make such extrapolations uncertain. Chronic nickel (Ni) toxicity data were compiled for temperate (24 species) and tropical (16 species) marine biota and their sensitivities to Ni compared. Concentrations to cause a 10% effect for temperate biota ranged from 2.9 to 20 300 µg Ni/L, with sea urchin larval development being the most sensitive endpoint. Values for tropical data ranged from 5.5 to 3700 µg Ni/L, with copepod early–life stage development being the most sensitive test. There was little difference in temperate and tropical marine sensitivities to Ni, with 5% hazardous concentrations (95% confidence interval) of 4.4 (1.8–17), 9.6 (1.7–26), and 5.8 (2.8–15) µg Ni/L for temperate, tropical, and combined temperate and tropical species, respectively. To ensure greater taxonomic coverage and based on guidance provided in Australia and New Zealand, it is recommended that the combined data set be used as the basis to generate a jurisdiction‐specific water quality guideline of 6 µg Ni/L for 95% species protection applicable to both temperate and tropical marine environments.

推导出热带和温带海水中镍的慢性准则值。

没有热带海洋水的慢性毒性数据,这限制了我们获得热带地区金属适当水质准则值的能力。为了帮助进行环境管理,通常将温度数据外推到其他气候(例如热带)地区。但是,温带和热带系统在气候,水化学和地方性生物区系方面的差异使得这种推断不确定。汇编了温带(24种)和热带(16种)海洋生物群的慢性镍(Ni)毒性数据,并比较了它们对Ni的敏感性。引起温带生物群影响10%的浓度范围为2.9至20300 µg Ni / L,其中海胆幼体发育是最敏感的终点。热带数据的数值范围为5.5至3700 µg Ni / L,co足类的生命早期发育是最敏感的测试。温带和热带海洋对Ni的敏感性几乎没有差异,5%危险浓度(95%置信区间)为4.4(1.8–17),9.6(1.7–26)和5.8(2.8–15)µg Ni / L分别适用于温带,热带以及温带和热带混合物种。为了确保更大的生物分类覆盖范围,并根据澳大利亚和新西兰提供的指导,建议将合并的数据集用作基础,以生成适用于特定司法管辖区的水质指导原则,以6 µg Ni / L的质量进行95%的物种保护温带和热带海洋环境。Ni / L分别为温带,热带和温带与热带混合物种的9.6(1.7–26)和5.8(2.8–15)µg Ni / L。为了确保更大的生物分类覆盖范围,并根据澳大利亚和新西兰提供的指导,建议将合并的数据集用作基础,以生成适用于特定司法管辖区的水质指导原则,以6 µg Ni / L的质量进行95%的物种保护温带和热带海洋环境。Ni / L分别为温带,热带和温带与热带混合物种的9.6(1.7–26)和5.8(2.8–15)µg Ni / L。为了确保更大的生物分类覆盖范围,并根据澳大利亚和新西兰提供的指导,建议将合并的数据集用作基础,以生成适用于特定司法管辖区的水质指导原则,以6 µg Ni / L的质量进行95%的物种保护温带和热带海洋环境。2020年《环境毒理学》; 39:2540–2551。©2020作者。Wiley Periodicals LLC代表SETAC发布的《环境毒理学和化学》。
