Nickel laterite ore deposits are becoming increasingly important sources of Ni for the global marketplace and are found mainly in tropical and subtropical regions, including Indonesia, the Philippines, Papua New Guinea, Cuba, and New Caledonia. There are few legislatively derived standards or guidelines for the protection of aquatic life for Ni in many of these tropical regions, and bioavailability-based environmental risk assessment (ERA) approaches for metals have mainly been developed and tested in temperate regions, such as the United States and Europe. This paper reports on a multi-institutional, 5-y testing program to evaluate Ni exposure, effects, and risk characterization in the Southeast Asia and Melanesia (SEAM) region, which includes New Caledonia, Papua New Guinea, the Philippines, and Indonesia. Further, we have developed an approach to determine if the individual components of classical ERA, including effects assessments, exposure assessments, and risk characterization methodologies (which include bioavailability normalization), are applicable in this region. A main conclusion of this research program is that although ecosystems and exposures may be different in tropical systems, ERA paradigms are constant. A large chronic ecotoxicity data set for Ni is now available for tropical species, and the data developed suggest that tropical ecosystems are not uniquely sensitive to Ni exposure; hence, scientific support exists for combining tropical and temperate data sets to develop tropical environmental quality standards (EQSs). The generic tropical database and tropical exposure scenarios generated can be used as a starting point to examine the unique biotic and abiotic characteristics of specific tropical ecosystems in the SEAM region.

在东南亚和美拉尼西亚开发基于生物利用度的镍风险评估框架

镍红土矿床正成为全球市场日益重要的镍来源,主要分布在热带和亚热带地区,包括印度尼西亚、菲律宾、巴布亚新几内亚、古巴和新喀里多尼亚。在这些热带地区,镍的水生生物保护几乎没有立法衍生的标准或指南,基于生物利用度的金属环境风险评估 (ERA) 方法主要在温带地区开发和测试,例如美国国家和欧洲。本文报告了一个多机构、5 年的测试计划,以评估东南亚和美拉尼西亚 (SEAM) 地区的镍暴露、影响和风险特征,其中包括新喀里多尼亚、巴布亚新几内亚、菲律宾和印度尼西亚。更远,我们开发了一种方法来确定经典 ERA 的各个组成部分,包括影响评估、暴露评估和风险表征方法(包括生物利用度标准化)是否适用于该地区。该研究计划的一个主要结论是,尽管热带系统中的生态系统和暴露可能不同,但 ERA 范式是不变的。现在有大量的 Ni 慢性生态毒性数据集可用于热带物种,所开发的数据表明热带生态系统并不是对 Ni 暴露特别敏感;因此,科学支持将热带和温带数据集结合起来制定热带环境质量标准 (EQS)。2021 年整合环境评估管理;17:802–813。© 2021 作者。由 Wiley Periodicals LLC 代表环境毒理学与化学学会 (SETAC) 出版的综合环境评估和管理
