Ultraviolet (UV) filters used in sunscreens are among the anthropogenic substances that may enter the marine environment by both indirect (via wastewater) and direct pathways (leisure activities). Owing to the recent global decline in coral population, the impact of those UV filters on the coral health is currently under increased investigation. First results from scientists suggest that some of the filters may be toxic to various coral life stages, but an initial cross comparison with existing data from other freshwater organisms does not indicate that corals are specifically more susceptible to UV filters than other standard species. In fact, the available data leading to this conclusion is still vague and based on toxicity and bioaccumulation tests with corals, which are both still at the research stage. To facilitate a proper hazard assessment, robust experimental procedures for coral ecotoxicological studies are considered mandatory. In other words, additional steps should be taken to standardize and validate such new test systems to generate reliable results, which then can be used in regulatory decision making. Furthermore, to facilitate a more detailed and site-specific environmental risk assessment in the marine area, an application-based exposure scenario must be developed. Until these data and tools become available, environmental hazard and risk assessments may be carried out using existing data from freshwater organisms and existing tonnage-based exposure scenarios as a potential surrogate.

防晒霜中使用的紫外线过滤剂——目前缺乏对珊瑚的保护？

防晒霜中使用的紫外线 (UV) 过滤器是可能通过间接（通过废水）和直接途径（休闲活动）进入海洋环境的人为物质之一。由于最近全球珊瑚数量下降，这些紫外线过滤剂对珊瑚健康的影响目前正在增加调查中。科学家的初步结果表明，一些过滤器可能对珊瑚的各个生命阶段有毒，但与其他淡水生物的现有数据的初步交叉比较并未表明珊瑚比其他标准物种更容易受到紫外线过滤器的影响。事实上，导致这一结论的现有数据仍然含糊不清，并且基于对珊瑚的毒性和生物蓄积性测试，两者都仍处于研究阶段。为了便于进行适当的危害评估，珊瑚生态毒理学研究的稳健实验程序被认为是强制性的。换句话说，应该采取额外的步骤来标准化和验证这种新的测试系统，以产生可靠的结果，然后可以将其用于监管决策。此外，为了促进在海洋区域进行更详细和特定地点的环境风险评估，必须开发基于应用程序的暴露场景。在这些数据和工具可用之前，可以使用来自淡水生物的现有数据和现有的基于吨位的暴露场景作为潜在的替代物来进行环境危害和风险评估。应该采取额外的步骤来标准化和验证这种新的测试系统，以产生可靠的结果，然后可以将其用于监管决策。此外，为了促进在海洋区域进行更详细和特定地点的环境风险评估，必须开发基于应用程序的暴露场景。在这些数据和工具可用之前，可以使用来自淡水生物的现有数据和现有的基于吨位的暴露场景作为潜在的替代物来进行环境危害和风险评估。应该采取额外的步骤来标准化和验证这种新的测试系统，以产生可靠的结果，然后可以将其用于监管决策。此外，为了促进在海洋区域进行更详细和特定地点的环境风险评估，必须开发基于应用程序的暴露场景。在这些数据和工具可用之前，可以使用来自淡水生物的现有数据和现有的基于吨位的暴露场景作为潜在的替代物来进行环境危害和风险评估。Integr Environ Assess Manag 2021；17:926-939。© 2021 SETAC
