Groundwater eDNA sources, including plant and animal life, are discussed in this article, along with their applications in determining salinity, water quality, and ecosystem dynamics. In groundwater ecosystems, eDNA is invaluable in detecting species that are otherwise difficult to monitor due to the subterranean nature of the habitat. Interpretation limitations (e.g. lack of reference databases) and technical challenges (e.g. contamination, extraction and detection techniques) are key concerns in GDE.

Recently, IAS have been proposed as bioindicators in environmental chemistry, offering an innovative approach to chemical pollution monitoring. Their adaptability, resilience, and widespread distribution enable the assessment of contaminant bioaccumulation, particularly in degraded habitats where native species are rare or protected, minimizing additional ecological stress. This mini-review examines the emerging use of IAS, such as bivalves, crustaceans, fish, mammals, and plants, in detecting a wide range of contaminants. A targeted literature search (2022–2024) identified 15 peer-reviewed studies demonstrating the potential of IAS in monitoring trace elements, persistent pollutants, and emerging contaminants. For instance, bivalves such as <em>Dreissena polymorpha</em> accumulate mercury, crustaceans like <em>Procambarus clarkii</em> reflect microplastic pollution, and semiaquatic mammals such as <em>Myocastor coypus</em> provide insights into wetland microplastic contamination through fecal analysis. However, IAS are not yet integrated into established biomonitoring programs and are currently used only in individual case studies or research efforts. The main limitation lies in physiological and ecological differences between IAS and native species, which can lead to variable bioaccumulation patterns and complicate ecological risk assessments. Additional challenges include ethical considerations, regulatory constraints, and methodological inconsistencies across studies. Addressing these challenges through refined protocols, molecular tools, and appropriate risk mitigation will be crucial for integrating IAS into environmental monitoring frameworks. This strategy can complement existing methods, improving chemical pollution tracking while supporting global efforts to manage contamination and protect biodiversity.</div></div>","PeriodicalId":52296,"journal":{"name":"Current Opinion in Environmental Science and Health","volume":"45 ","pages":"Article 100620"},"PeriodicalIF":6.7,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143895646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
