Influence of meteorological conditions on atmospheric microplastic transport and deposition

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.
