摘要
基于文献报道,首先着眼于大气中微塑料的污染现状及其进入人类呼吸系统的证据,重点介绍大气微塑料的丰度、成分、形状和大小等分布特征;其次归纳总结微塑料呼吸道暴露对机体健康的潜在影响;最后对今后研究中需重视并完善微塑料或更小尺寸纳塑料的潜在危害、进一步加强大气微塑料的呼吸道暴露特征分析、健康风险评估、毒性机理研究等问题进行分析与展望.
Abstract
In this review,the pollution status of atmospheric microplastics was introduced,with a focus on its distribution characteristics,such as abundance,composition,shape,and size,as well as the evidence of microplastics in human respiratory system.Further,the potential health effects of respiratory exposure to microplastics were summarized.Lastly,some prospects were proposed for future research,including emphasizing and improving the knowledge on potential harmful effects of microplastics or smaller sized nanoplastics,and strengthening the exposure characteristics analysis,health risk assessment,and the toxicological mechanistic investigations.
