“…We estimated that 1.4% of the total atmospheric MP emissions by mass (0.70% for pellets, 11% for fragments, and 7.8% for lines) from land surfaces deposited to the ocean via atmospheric transport. A previous Lagrangian model study estimated that 15–16% of the mass of MP lines emitted into the global atmosphere was transported to the open ocean, 34 comparable with our mechanistic calculations for MP fragments and lines.…”

“…We evaluated our simulations against additional measurements of suspended atmospheric MP concentrations 33 − 36 and deposited atmospheric MP fluxes (fluxes of MPs deposited from the atmospheres) 29 , 34 , 37 , 38 at 19 East Asian coastal sites and 56 locations in the Indian Ocean and the South China Sea ( Figure S1 and Table S1 ). The deposited MP fluxes were measured between October 2016 and June 2019 by four different research groups using generally consistent sampling and analytical methods.…”

“… 33 − 36 At Lianyungang and Tianjin, measurements of suspended atmospheric MPs and deposited atmospheric MP fluxes were both available. However, the measurements were not sampled concurrently and analyzed with different methods 28 , 34 ( Figure S1 and Table S1 ). All measurements of suspended and deposited atmospheric MPs used in this study found MP lines to be the dominant shape by both number and mass ( Table S1 ).…”

We developed a regional atmospheric transport model for microplastics (MPs, 10 μm to 5 mm in size) over Asia and the adjacent Pacific and Indian oceans, accounting for MPs’ size- and shape-dependent aerodynamics. The model was driven by tuned atmospheric emissions of MPs from the land and the ocean, and the simulations were evaluated against coastal ( n = 19) and marine ( n = 56) observations. Our tuned atmospheric emissions of MPs from Asia and the adjacent oceans were 310 Gg y –1 (1 Gg = 1 kton) and 60 Gg y –1 , respectively. MP lines and fragments may be transported in the atmosphere >1000 km; MP pellets in our model mostly deposited near-source. We estimated that 1.4% of the MP mass emitted into the Asian atmosphere deposited into the oceans via atmospheric transport; the rest deposited over land. The resulting net atmospheric transported MP flux from Asia into the oceans was 3.9 Gg y –1 , twice as large as a previous estimate for the riverine-transported MP flux from Asia into the oceans. The uncertainty of our simulated atmospheric MP budget was between factors of 3 and 7. Our work highlighted the impacts of the size and morphology on the aerodynamics of MPs and the importance of atmospheric transport in the source-to-sink relationship of global MP pollution.

In recent years, the focus of microplastic research has begun to observe a shift from the marine towards terrestrial and freshwater environments. This is in response to a greater awareness of the predominance of land-based sources in marine microplastic contamination. In this regard, terrestrial and freshwater environments are often perceived as conduits for microplastic particles to the oceans, but this overlooks substantial and important complexities associated with these systems, as well as the need to protect these ecosystems in their own right. This chapter focuses on several critical sources and pathways deemed to be highly important for the release of microplastics to the environment. These include road-associated microplastic particles (RAMP) and emissions related to agriculture that are, thus far, under-researched. Transfers and accumulations of particles within terrestrial and freshwater systems are also reviewed, including the state of knowledge on the occurrence of microplastics in different environmental compartments (air, water, sediments, biota). Methodological constraints are addressed, with particular focus on the need for greater harmonisation along all stages of sampling, analysis, and data handling. Finally, the chapter discusses the ultimate fate of particles released to terrestrial and freshwater environments and highlights critical research gaps that should be addressed to evolve our understanding of microplastic contamination in complex and dynamic environmental systems.
