| Abstract: | With rapid development and application of nanotechnology, there is an increasing concern over the environmental fate, behavior, toxicity, exposure and risk of engineered nanomaterials (ENMS). In this review, we presented the release pathways of ENMS into the environment and their potential environmental behavior with a focus on the suspension and aggregation of ENMS and their interactions with dissolved organic matter and contaminants. In addition, toxicity of several types of engineered ENMS to various organisms was discussed. Then, we concluded with the future research perspectives of engineered ENMS. |
