Abstract

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.
