Contaminants of emerging concern (CECs) present a threat to the functioning of freshwater ecosystems. Their spread in the environment can affect both plant and animal health. Ecohydrology serves as a solution for assessment approaches (i.e., threat identification, ecotoxicological assessment, and cause–effect relationship analysis) and solution approaches (i.e., the elaboration of nature-based solutions: NBSs), mitigating the toxic effect of CECs. However, the wide array of potential molecular analyses are not fully exploited in ecohydrological research. Although the number of publications considering the application of molecular tools in freshwater studies has been steadily growing, no paper has reviewed the most prominent studies on the potential use of molecular technologies in ecohydrology. Therefore, the present article examines the role of molecular methods and novel omics technologies as essential tools in the ecohydrological approach to CECs management in freshwater ecosystems. It considers DNA, RNA and protein-level analyses intended to provide an overall view on the response of organisms to stress factors. This is compliant with the principles of ecohydrology, which emphasize the importance of multiple indicator measurements and correlation analysis in order to determine the effects of contaminants, their interaction with other environmental factors and their removal using NBS in freshwater ecosystems.

分子方法作为淡水生态系统中新兴污染物生态水文学研究的潜在工具

新出现的污染物 (CEC) 对淡水生态系统的功能构成威胁。它们在环境中的传播会影响植物和动物的健康。生态水文学作为评估方法(即威胁识别、生态毒理学评估和因果关系分析)和解决方法(即制定基于自然的解决方案:NBS)的解决方案,减轻了 CEC 的毒性影响。然而,在生态水文研究中尚未充分利用各种潜在的分子分析。尽管考虑在淡水研究中应用分子工具的出版物数量一直在稳步增长,但没有一篇论文回顾了关于分子技术在生态水文学中的潜在用途的最突出研究。所以,本文研究了分子方法和新型组学技术作为淡水生态系统中 CEC 管理的生态水文学方法的重要工具的作用。它考虑了 DNA、RNA 和蛋白质水平的分析,旨在提供生物体对压力因素反应的整体视图。这符合生态水文学的原则,该原则强调多指标测量和相关性分析的重要性,以确定污染物的影响、它们与其他环境因素的相互作用以及在淡水生态系统中使用 NBS 去除污染物。RNA 和蛋白质水平分析旨在提供生物体对压力因素反应的整体视图。这符合生态水文学的原则,该原则强调多指标测量和相关性分析的重要性,以确定污染物的影响、它们与其他环境因素的相互作用以及在淡水生态系统中使用 NBS 去除污染物。RNA 和蛋白质水平分析旨在提供生物体对压力因素反应的整体视图。这符合生态水文学的原则,该原则强调多指标测量和相关性分析的重要性,以确定污染物的影响、它们与其他环境因素的相互作用以及在淡水生态系统中使用 NBS 去除污染物。
