Abstract

Purpose of the Review

Climate change is intensifying the pressures on aquatic ecosystems by altering the dynamics of contaminants, with cascading effects on ecological and human health. This review synthesizes recent evidence on how rising temperatures, altered precipitation patterns, and extreme weather events influence chemical and microbial contaminant dynamics in aquatic environments.

Recent Findings

Key findings reveal that elevated temperatures enhance phosphorus pollution and algal blooms, increase heavy metal release from sediments, and promote the mobilization of organic pollutants. Concurrently, climate change exacerbates microbial contamination by facilitating the spread of waterborne microbial contaminants, especially posing more pressure to antimicrobial resistance-related contaminants through temperature-driven horizontal gene transfer and extreme precipitation events. Complex interactions between chemical and microbial contaminants like heavy metals co-selecting for antibiotic resistance further amplify risks. The compounded effects of climate change and contaminants threaten water quality, ecosystem resilience, and public health, particularly through increased toxicant exposure via seafood and waterborne disease outbreaks. Despite growing recognition of these interactions, critical gaps remain in understanding their synergistic mechanisms, especially in data-scarce regions.

Summary

This review highlights the urgent need for integrated monitoring, predictive modeling, and adaptive policies under a One Health framework to mitigate the multifaceted impacts of climate-driven contamination. Future research should prioritize real-world assessments of temperature effects, urban overflow dynamics during extreme weather, and the socio-behavioral dimensions of contaminant spread to inform effective mitigation strategies.

气候变化和水生生态系统污染物对环境-人类健康的交互影响
气候变化正在通过改变污染物的动态而加剧对水生生态系统的压力,并对生态和人类健康产生级联效应。这篇综述综合了最近关于温度上升、降水模式改变和极端天气事件如何影响水生环境中化学和微生物污染物动态的证据。主要研究结果表明,温度升高会加剧磷污染和藻华,增加沉积物中重金属的释放,并促进有机污染物的动员。同时,气候变化通过促进水生微生物污染物的传播加剧了微生物污染,特别是通过温度驱动的水平基因转移和极端降水事件对抗菌素耐药性相关污染物施加了更大的压力。化学污染物和微生物污染物(如重金属)之间复杂的相互作用进一步扩大了抗生素耐药性的风险。气候变化和污染物的复合影响威胁着水质、生态系统恢复力和公众健康,特别是通过海产品和水传播疾病暴发而增加的毒物暴露。尽管人们越来越认识到这些相互作用,但在理解它们的协同机制方面仍然存在重大差距,特别是在数据匮乏的地区。本综述强调迫切需要在“同一个健康”框架下进行综合监测、预测建模和适应性政策,以减轻气候驱动污染的多方面影响。未来的研究应优先考虑对温度影响、极端天气下城市溢出动态以及污染物扩散的社会行为维度的实际评估,以提供有效的缓解策略。
