| 摘 要： | 微塑料是粒径小于5 mm的塑料颗粒,纳米塑料是粒径小于1μm的塑料颗粒.微/纳米塑料广泛存在于各种环境介质中,由于其粒径小、比表面积大,很容易被直接吸入、经口食入或皮肤浸入至体内,造成毒害作用,危害健康.本文主要总结了环境中微/纳米塑料在水、大气、土壤和食品中的污染现状,阐述了其对生物体可能产生的毒性效应,探讨了其对人体健康造成的不良影响.最后本文在总结现有研究的基础上,对未来微/纳米塑料的毒性效应和健康危害的研究方向进行了分析和展望.

| Abstract: | Microplastics are plastic particles with size less than 5 mm, while nano-plastics are plastic particles with size less than 1 μm. Micro-and nano-plastics are widely existed in the environment. Because of their small particle size and large specific surface area, they are easy to be directly inhaled, ingested via mouth or immersed into the body by skin, resulting in toxicity and adverse health effects. This paper mainly summarizes the occurrences and analysis methods of micro-/nano-plastics in the environment, the toxic effects, and the possible effects on the human health. Furthermore, this review provides insights for further research in the field of the toxicity and health effects of micro-/nano-plastics. |
