The 20th Pollutant Responses in Marine Organisms (PRIMO 20) conference provided a forum for scientists from around the world to communicate novel toxicological research findings specifically focused on aquatic organisms, by combining applied and basic research at the intersection of environmental and mechanistic toxicology. The work highlighted in this special issue of Aquatic Toxicology, a special issue of Marine Environmental Research, and presented through posters and presentations, encompass important and emerging topics in freshwater and marine toxicology. This includes multiple types of emerging contaminants including microplastics and UV filtering chemicals. Other studies aimed to further our understanding of the effects of endocrine disrupting chemicals, pharmaceuticals, and personal care products. Further research presented in this virtual issue examined the interactive effects of chemicals and pathogens, while the final set of manuscripts demonstrates continuing efforts to combine traditional biomonitoring, data from -omic technologies, and modeling for use in risk assessment and management. An additional goal of PRIMO meetings is to address the link between environmental and human health. Several articles in this issue of Aquatic Toxicology describe the appropriateness of using aquatic organisms as models for human health, while the keynote speakers, as described in the editorial below, presented research that highlighted bioaccumulation of contaminants such as PFOS and mercury from fish to marine mammals and coastal human populations such as the Gullah/GeeChee near Charleston, South Carolina, USA.

第 20 届海洋生物污染物反应 (PRIMO 20) 会议为来自世界各地的科学家提供了一个论坛，通过结合环境毒理学和机械毒理学交叉领域的应用和基础研究，交流专门针对水生生物的毒理学研究新发现。本期水生毒理学特刊重点介绍了这项工作，海洋环境研究特刊，并通过海报和演示文稿呈现，涵盖淡水和海洋毒理学中的重要和新兴主题。这包括多种类型的新兴污染物，包括微塑料和紫外线过滤化学品。其他研究旨在进一步了解内分泌干扰化学品、药物和个人护理产品的影响。在这个虚拟问题中提出的进一步研究检查了化学品和病原体的相互作用，而最后一组手稿展示了将传统生物监测、来自组学技术的数据以及用于风险评估和管理的建模结合起来的持续努力。PRIMO 会议的另一个目标是解决环境与人类健康之间的联系。本期Aquatic Toxicology的几篇文章描述了使用水生生物作为人类健康模型的适当性，而主旨发言人（如以下社论所述）介绍了强调污染物（例如全氟辛烷磺酸和汞）从鱼类生物累积到海洋哺乳动物和沿海人口（例如 Gullah）的研究/GeeChee 靠近美国南卡罗来纳州查尔斯顿。
