Assessing spatial variability and source identification of heavy metals in agricultural soils: A geostatistical and multivariate analysis of coastal eastern Zhejiang, China
Researchers used geostatistical and multivariate analysis techniques to assess the spatial variability and sources of five heavy metals in agricultural soils along the coast of eastern Zhejiang, China. While focused primarily on heavy metals rather than microplastics, the study provides methodology relevant to understanding pollutant distribution in coastal agricultural areas. The findings identified industrial emissions, agricultural practices, and natural geological processes as key contamination sources.
Physicochemical properties of environmental media can affect the adsorption of arsenic (As) by microplastics
Researchers found that microplastics in farmland soil can absorb arsenic, a known carcinogen, and that the amount absorbed depends on soil properties like organic matter content and nutrient levels. This is the first study to examine microplastic-arsenic interactions in natural soil conditions across 12 Chinese provinces. The findings are important for human health because microplastics carrying arsenic in agricultural soil could increase the transfer of this toxic element into food crops.
The potentiality of GIS for assessing soil pollution – A review
Not relevant to microplastics — this review examines how Geographic Information Systems (GIS) can be applied to assess and map soil pollution from heavy metals, pesticides, and other contaminants, with no substantive microplastics content.
Characterizing surface soil heavy metal contamination and source attribution in the Qinghai Lake Basin
Researchers analyzed 227 soil samples across China's Qinghai Lake Basin to map heavy metal contamination, finding generally low pollution levels with transportation as a key source; they recommend future research examine the combined threat of heavy metals and microplastics in alpine ecosystems.
Using machine learning to reveal drivers of soil microplastics and assess their stock: A national-scale study
Using machine learning on data from 621 sites across China, researchers identified nine key factors driving microplastic distribution in soil, including population density, plastic production, and agricultural practices. The study estimated that Chinese topsoil contains a substantial stock of microplastics, with concentrations varying widely by region. This large-scale analysis helps predict where microplastic contamination is worst, which is important for understanding human exposure through food grown in contaminated soil.
Environmental Risk Assessment of Polycyclic Aromatic Hydrocarbons in Farmland Soils near Highways: A Case Study of Guangzhou, China
Researchers assessed polycyclic aromatic hydrocarbon (PAH) contamination in roadside farmland soils near highways in Guangzhou, China across seasons, finding that PAH levels near high-traffic roads were significantly elevated above background. Vehicle emissions and tire wear were identified as the primary PAH sources, with carcinogenic risk scores exceeding safe thresholds at several sites.

Scientists measured potentially toxic metals (copper, lead, zinc, nickel, chromium, arsenic) in urban soils across the city of Santiago de Compostela, Spain, finding elevated concentrations in areas with heavy traffic and industrial activity. The study highlights how urban land use drives heavy metal contamination, which often co-occurs with microplastic pollution.
