Atmospheric microplastics are of great concern because of their potential impact on the environment and human health. Although several studies have shown the presence of large quantities of microplastics in the air, questions about the transport and deposition of microplastics in the atmosphere remain unanswered. Based on these shortcomings, this review provides a comprehensive overview of the influence of meteorological conditions on atmospheric microplastic fate. Dry and wet deposition are the main removal mechanisms for atmospheric microplastic. Furthermore, by exploring how wind facilitates the long-range transport of microplastics between terrestrial and marine ecosystems, establishing a global microplastic cycle. Besides, this review also examines the effects of other meteorological conditions on atmospheric microplastic transport. Characteristics of current atmospheric microplastic models are summarized, particularly with respect to the consideration of meteorological conditions. Finally, we propose future research directions and mitigation measures for atmospheric microplastic pollution, which are necessary for mitigating atmospheric microplastic pollution and protecting ecosystems and human health.
大气微塑料因其对环境和人类健康的潜在影响而备受关注。尽管多项研究已表明空气中存在大量微塑料，但关于微塑料在大气中的传输和沉降问题仍未得到解答。基于这些不足，本综述全面概述了气象条件对大气微塑料归宿的影响。干沉降和湿沉降是大气微塑料的主要清除机制。此外，通过探究风如何促进微塑料在陆地和海洋生态系统之间的长距离传输，建立了全球微塑料循环。此外，本综述还研究了其他气象条件对大气微塑料传输的影响。总结了当前大气微塑料模型的特点，特别是在气象条件考虑方面。最后，我们提出了大气微塑料污染的未来研究方向和缓解措施，这对于减轻大气微塑料污染、保护生态系统和人类健康至关重要。
