“…First, we attempt to compile soil concentrations of microplastics. Soil microplastic concentrations are usually reported in different microplastic size ranges. − Thus, comparing soil microplastic concentrations reported globally is not straightforward, and data normalization is needed. After reviewing the reported size distributions of global soil microplastic, we found almost all of the mass size distributions of soil microplastic concentration follow a single probability density function (Figure a) (see the calculation methods in Text S7).…”

To bridge the gap in understanding soil−air microplastic emissions, here we studied the soil−air transfer mechanism of microplastics with laboratory simulations using microplastic particles varying in size from 1 to 5000 μm. Our findings indicate that the size and shape of the microplastics together with the soil type and moisture levels are major determinants of the microplastic enrichment ratio (ER) in dust, overshadowing the role of polymer types. Notably, microplastic pellets larger than 20 μm do not enrich in dust, while microplastic fibers, even those as large as 500−5000 μm in length, do enrich in dust. Based on our ER measurement, the global microplastic size distribution in soil and dust aerosol production flux, we made a preliminary bottom-up assessment of global soil microplastic emissions of 48[0.4−1217] kilotons/year. Our pioneering findings on the global atmospheric soil−air microplastic flux provide insights that could guide the future development of a more precise microplastic emission inventory.

“…1) Pollution of plastic mulch: From 2000 to 2016, amount of mulch used in China was increased from 724,000 tons to 1.468 million tons, reaching a peak and accounting for about 70% of the world's total, covering an area of nearly 1.77 hm 2 × 10 7 hm 2 and accounting for 90% of the world's total coverage (Bigalke et al, 2021;Bian et al, 2015). With the promulgation of the "Soil Pollution Prevention and Control Plan" and the plastic restriction order, China's agricultural film production will drop to 774,000 tons in 2020 (Guo et al, 2020).…”

“…2) Agricultural irrigation pollution: Since the concentration of microplastics in surface water is 1.00 × 10 −5 to 1.00×10 5 /L (Olubukola et al, 2018;Mak et al, 2020), the use of surface water and domestic sewage irrigation caused microplastics to re-accumulate in the soil. Bigalke et al found that microplastic emissions from agricultural drainage in Switzerland were 9.3×10 12 per year (Bigalke et al, 2021). 3) Fertilization pollution of excess sludge products: According to statistics, the amount of microplastics from sludge fertilization in European farmland was ranged from 63,000 to 430,000 tons each year, and the amount of microplastics in North American farmland was increased from 44,000 to 300,000 tons, which exceeding the pollution concentration of surface seawater (Hao et al, 2021;Lares et al, 2018).…”

Microplastics are characterized with universality, persistence and toxicity to aquatic organisms, the pollution of microplastics has attracted worldwide attention. At present, studies on microplastic pollution were mainly focused on the composition, abundance and species of microplastics in water bodies and sediments, and few studies were focused on the source and influence characteristics of microplastics in surface water bodies. Starting from the sources of microplastic pollution in surface water of this paper, the pollution status of agricultural microplastics was analyzed, and the importance and urgency of studying microplastic pollution in agricultural non-point sources were put forward. Therefore, it was intended to provide effective scientific basis and technical support for the control of microplastics non-point source pollution in river basins.

“…While research on microplastics in freshwaters has recently received increasing attention (Bigalke et al, 2022 ; Liu et al, 2022 ; Wu et al, 2022 ; Xiang et al, 2022 ), there remains a notable absence of studies addressing microplastics in crayfish and western fluvial systems. We investigated the presence of microplastics in invasive signal crayfish Pacifastacus leniusculus populations in streams situated in North Yorkshire, Northern England, UK.…”

Microplastics are a globally pervasive pollutant with the potential to directly impact species and accumulate in ecosystems. However, there remains a relative paucity of research addressing their accumulation in freshwater ecosystems and a near absence of work in crayfish, despite their high ecological and economic importance. This study investigated the presence of microplastics in the invasive signal crayfish Pacifastacus leniusculus along a stream urbanization gradient. The results demonstrate a ubiquitous presence of microplastics in crayfish digestive tracts at all sites and provide the first evidence of microplastic accumulation in tail tissue. Evidence of a positive linear trend was demonstrated between microplastic concentration in crayfish and upstream urban area size in generalized linear models. Evidence for a positive effect of the upstream urban area and a negative effect of crayfish length on microplastic concentrations in crayfish was demonstrated in multiple generalized linear regression models. Our results extend the current understanding of microplastics presence in freshwater ecosystems and demonstrate their presence in crayfish in the wild for the first time.
