Mechanisms underlying the toxicity of microplastics to mammals: a review / 预防医学

@#As a new type of environmental pollutants, microplastics are widely distributed in the global ecosystem, and ingestion of microplastics may produce a number of toxic effects. Based on currently available publications, this paper describes the main pathways of exposure to microplastics, and summarizes the toxic mechanisms of microplastics in mammals, including oxidative stress, inflammatory response, immune damage, imbalance of gut microbiota, energy metabolism disorder and DNA damage, so as to provide insights into elucidation of the toxic mechanism mechanisms and health risk assessment of microplastics.
