ClearCharacterizing 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.
Characteristics of Soil Heavy Metal Pollution and Health Risks in Chenzhou City
Researchers analyzed 600 soil samples in Chenzhou City, China, and found that while most areas had low to moderate heavy metal contamination, about 3% of samples showed high ecological risk from metals like mercury and cadmium near industrial zones. While focused on heavy metals rather than microplastics, the study is relevant because microplastics in soil can absorb and transport these same toxic metals, potentially increasing human exposure through crops grown in contaminated areas.
Heavy metal pollution and ecological risk under different land use types: based on the similarity of pollution sources and comparing the results of three evaluation models
Researchers analyzed heavy metal contamination across five land use types on the Qinghai-Tibet Plateau, finding that industrial activities like metallurgy and mining were the primary sources of cadmium, copper, and lead pollution, with the highest risk levels in watered and urban lands rather than grasslands.

This review examines how heavy metals from factories, vehicle emissions, and improper waste disposal accumulate in urban soils and affect human health. Exposure to these contaminated soils has been linked to breathing problems, brain disorders, and general toxicity. The findings highlight the need for soil monitoring and cleanup strategies to protect city residents.
Distribution of microplastics in the soils of a petrochemical industrial region in China: Ecological and Human Health Risks
Researchers surveyed microplastic contamination in soils across a major petrochemical industrial region in China and found concentrations ranging from 714 to over 11,000 particles per kilogram. Educational land had the highest contamination levels, and ecological risk assessments showed nearly all land-use types were at the highest risk level. The study also found that infants face significantly higher daily microplastic exposure than adults, underscoring the need for targeted pollution management in industrial urban areas.
Characterizing Surface Soil Heavy Metal Contamination and Source Attribution in the Qinghai Lake Basin
Researchers collected 227 surface soil samples across the Qinghai Lake Basin to characterize the spatial distribution and source attribution of twelve heavy metals using enrichment factors, geo-accumulation indices, and absolute principal component analysis, distinguishing natural geogenic contributions from anthropogenic inputs.
Impact Imposed by Urbanization on Soil Heavy Metal Content of Lake Wetland and Evaluation of Ecological Risks in East Dongting Lake in China
This Chinese study measured heavy metal contamination in wetland soils of East Dongting Lake, finding elevated concentrations of several metals linked to nearby industrial and agricultural activities. Wetland contamination with heavy metals often co-occurs with microplastic pollution, and these combined stressors can have synergistic harmful effects on wetland ecosystems.
Spatial and temporal variability of Cadmium and Lead in Urban Soils of Thessaloniki (northern Greece).
This study monitored cadmium and lead contamination in urban soils of Thessaloniki, Greece over two years, finding variable heavy metal levels linked to traffic and industrial activity. Heavy metals and microplastics frequently co-occur in urban environments and can interact to increase combined toxicity.
Asia’s soil contamination crisis: causes, consequences, and sustainable solutions: a comprehensive review
This review addresses Asia's soil contamination crisis, examining how rapid urbanization, intensive agriculture, and poor waste management have created widespread heavy metal and microplastic soil pollution threatening food security, biodiversity, and human health across the continent.
Characterization of microplastics and the association of heavy metals with microplastics in suburban soil of central China
Microplastics in suburban soils of central China were characterized across three land-use types, with woodland containing the highest concentrations (4.1×10³ particles/kg) and 81.7% of particles under 100 μm, while XRF analysis confirmed heavy metals were enriched on plastic surfaces compared to surrounding soil. The study confirms that smaller microplastics are the dominant form and can act as carriers for heavy metal contamination in urban-adjacent soils.
Microplastics in Urban Soils From Different Land Use Activities of Cyberjaya (Malaysia): Exploring Occurrence, Relationships, Sources and Pollution Level
Researchers surveyed urban soils across five different land uses in Cyberjaya, Malaysia, and found microplastics in all of them, with construction areas showing the highest concentrations. The types of plastic particles varied by location, suggesting that the sources and characteristics of soil microplastic contamination depend on what activities take place in that area.
Risk assessment and zoning of soil microplastics in a typical megacity, China
Researchers mapped microplastic contamination across soils in Nanjing, a major Chinese city, and found that risk levels varied significantly by location. Residential areas, government districts, and industrial zones showed the highest concentrations, with washing-related activities and soil properties being key factors influencing pollution levels. The study provides a risk-based zoning framework that could help city planners prioritize cleanup and prevention efforts in the most affected areas.
Spatial distribution characteristics and pollution evaluation of soil heavy metals in Wulongdong National Forest Park
Researchers investigated the spatial distribution and pollution levels of seven heavy metals in soils across Wulongdong National Forest Park at different altitudes and slope orientations. The study found that while most heavy metal concentrations were near natural background levels, certain elements showed localized enrichment, highlighting the importance of monitoring even protected natural areas.
Characterization of Microplastics and Associated Heavy Metals in Urban Soils Affected by Anthropogenic Littering: Distribution, Spatial Variation, and Influence of Soil Properties
Researchers sampled soils across residential, commercial, and industrial land-use types in urban areas and found microplastics in every location, with polypropylene, polyethylene, and polyamide as the dominant polymer types, at concentrations up to 850,000 particles per kilogram. Heavy metals were also associated with the plastic particles, meaning microplastics in urban soil may serve as combined carriers of chemical toxicants. The findings highlight urban soil as a major but underappreciated reservoir of microplastic pollution.
