Environmental DNA (eDNA), as a recent research hotspot in environmental science, the use of eDNA in biological monitoring has the advantages of sensitivity and time/labor saving. The eDNA technology combined with scientific advancement has been applied in investigations of target species (such as invasive species, endangered species and other rare species), biomass, and biodiversity. In addition, ecotoxicology studies and environmental pollution impact assessments based on the development of eDNA technology have gradually emerged in recent years. In this article, we summarizes the application of eDNA in ecological assessment, include species diversity assessment and chemical contamination impacts assessment, provide guiding questions for study design. We additionally discuss current challenges associated with eDNA. Finally, looking to the future, we discuss the opportunities of eDNA technology in environmental protein, environmental sample processor and ecogenomic sensors.
环境 DNA（eDNA）作为环境科学的一个新兴研究热点，其在生物监测中的应用具有灵敏性和省时省力的优势。eDNA 技术与科学进步相结合，已应用于目标物种（如入侵物种、濒危物种和其他稀有物种）、生物量和生物多样性的调查中。此外，近年来基于 eDNA 技术的发展，生态毒理学研究和环境污染影响评估也逐渐出现。本文总结了 eDNA 在生态评估中的应用，包括物种多样性评估和化学污染影响评估，为研究设计提供了指导问题。我们还讨论了 eDNA 目前面临的挑战。最后，展望未来，我们讨论了 eDNA 技术在环境蛋白、环境样本处理器和生态基因组传感器方面的机遇。
