Emerging pollutants (EPs) are chemicals known to cause major impacts on the terrestrial, aquatic life and human health as a result of their chronic and acute toxicity. Although lots of studies on EPs behavior in the aquatic environment are currently available in literature, an urgent requirement exists to complete toxicological studies and develop and implement efficient and ecological methods for their removal. This paper raises some relevant problems related to water environment pollution with EPs, the risks they can generate for aquatic life and humans and opportunities to reduce the effects of pollution by EPs removal. Categories of emerging chemicals of concern in the environment, their sources, fate and impacts, with some examples are discussed. Organic UV filters are shortly presented as a relative new EPs category, with a focus on the need to develop extensive experimental studies on their environmental occurrence, fate and removal. Furthermore, sources for the aquatic environment resulting from discharging EPs directly into rivers from wastewater treatment plants are examined. The incidence of environmental and human health risks related to EPs is also considered. The removal of EPs from the environment as a solution to risk mitigation is addressed, with emphasis on several non-conventional processes involving biological removal of EPs. The paper provides a critical look at the current challenges posed by the presence of emerging pollutants in the aquatic environment, with critical comments and recommendations for further research to reduce the impact of EPs on water and human health and improve the performance of developed methods for their removal.

水环境中新兴污染物的发生，归宿及去除途径

新兴污染物（EPs）是已知的化学品，由于其慢性和急性毒性而对陆生，水生生物和人类健康产生重大影响。尽管目前有大量关于水环境中EPs行为的研究文献，但迫切需要完成毒理学研究并开发和实施有效的生态方法以去除它们。本文提出了与EPs污染水环境有关的一些相关问题，它们可能对水生生物和人类产生风险，以及通过去除EPs减少污染影响的机会。讨论了环境中令人关注的新兴化学品的类别，来源，命运和影响，并列举了一些例子。短期内将有机UV滤光片列为相对新的EP类别，着重于对环境的发生，命运和清除进行广泛的实验研究的需要。此外，还检查了由废水处理厂直接将EP排放到河流中而导致的水生环境来源。还考虑了与EP相关的环境和人类健康风险的发生率。解决从环境中去除EPs作为减轻风险的解决方案，并着重于涉及涉及生物去除EPs的几种非常规过程。本文对水生环境中新兴污染物的存在所带来的当前挑战进行了批判性研究，并提出了批判性评论和建议，以进行进一步的研究，以减少EPs对水和人类健康的影响，并改善已开发方法的性能。去除。
