Description of Research Group: To study the pollution process of toxic pollutants (e.g. heavy metals, persistent organic pollutants, nanomaterials, etc.) in the atmosphere, water and soil, to elucidate the migration and transformation rules of pollutants in multi-environmental media, to determine the toxic effects and toxicity mechanisms of pollutants on terrestrial organisms and aquatic organisms, to reveal the rules of pollutant transfer and enrichment and accumulation in the food chain, and to assess the impacts of pollutants on human health by means of in vitro cytotoxicity tests, so as to provide scientific basis for the protection of the environment and the management of pollutants.
