Microplastic and mesoplastic pollution in farmland soils in suburbs of Shanghai, China
Abstract
Microplastics are emerging pollutants which have been extensively detected in water environments. However, little is known about microplastic pollution in soil environments. In this study, we investigated microplastics and mesoplastics in farmland soils from twenty vegetable fields around the suburbs of Shanghai. In each site, three duplicate soil samples were collected from shallow (0-3 cm) and deep soils (3-6 cm), respectively. Microplastics (sizes of 20 μm - 5 mm) and mesoplastics (5 mm - 2 cm) were detected using methods of density extraction, 30% H2O2 digestion and micro-fourier transform infrared spectroscopy. The abundance of microplastics was 78.00 ± 12.91 and 62.50 ± 12.97 items kg-1 in shallow and deep soils, respectively. While, mesoplastics were found with abundance of 6.75 ± 1.51 and 3.25 ± 1.04 items kg-1 in shallow and deep soils. Among these micro(meso)plastics, 48.79% and 59.81% were in size of <1 mm in shallow and deep soils. The main morphotypes of microplastics included fiber, fragment and film, mostly in color of black or transparent. Moreover, we found that topsoil contained higher concentrations and larger sizes of micro(meso)plastics than deep soil. In addition, the vast majority of micro(meso)plastics were polypropylene (50.51%) and polyethylene (43.43%). This study reveals occurrence and characteristics of microplastic pollution in typical farmland soils. It provides important data for subsequent research on microplatics in the terrestrial ecosystem.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
