Advances in Studies on Heavy Metals in Urban Soil: A Bibliometric Analysis
This bibliometric analysis maps two decades of research on heavy metal contamination in urban soils, identifying key trends, leading researchers, and priority topics. The field has grown significantly, with focus areas including pollution source identification, health risk assessment, and the use of environmental magnetism techniques. While centered on heavy metals rather than microplastics, the research is relevant because microplastics in urban soil often carry and concentrate heavy metals, creating combined pollution that threatens human health.
Heavy Metal Contamination in Urban Soils: Health Impacts on Humans and Plants: A Review
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.
Urban geochemical changes and pollution with potentially harmful elements in seven Russian cities
Researchers measured concentrations of potentially harmful metals (lead, zinc, copper) in street dust and surface sediment across seven large Russian cities, reconstructing pre-industrial baselines to calculate how much human activity has changed local geochemistry. The study introduces new pollution ranking criteria that better capture city-specific contamination patterns than standard metrics.
Potentially Toxic Trace Elements in the Urban Soils of Santiago de Compostela (Northwestern Spain)
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.
Identification Sources and High-Risk Areas of Sediment Heavy Metals in the Yellow River by Geographical Detector Method
Scientists measured heavy metal contamination in river sediments of the Yellow River in Inner Mongolia, identifying industrial emissions and agricultural activities as the main sources. While focused on heavy metals, the research is relevant because microplastics frequently co-occur with and transport heavy metal pollutants in river systems.
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.
Freshly fallen snow with full of microplastics: A scientific research in Riga central and peripheral area, Latvia.
Researchers sampled freshly fallen snow at six locations around Riga, Latvia, and detected microplastics at all sites using µFTIR imaging, demonstrating that atmospheric deposition carries plastic particles across both urban and more rural areas of the city.
Tendencias metodológicas en la evaluación del grado de contaminación y de riesgos por metales pesados presentes en sedimentos viales urbanos
This systematic review (in Spanish) analyzes global trends in methods used to assess heavy metal contamination in urban road sediments from 1995 to 2018. While focused on metals rather than microplastics, the study covers assessment frameworks applicable to roadside pollution that can co-occur with plastic tire particles.
Traffic-related metals in urban snow cover: A review of the literature data and the feasibility of filling gaps by field data collection
Researchers reviewed the existing literature on traffic-related metal contamination in urban snow and found that zinc and copper were the metals of greatest environmental concern. They noted that comparing results across studies was difficult due to varying site conditions and sampling methods. The study identifies data gaps for less commonly measured metals and highlights urban snow as a transport medium for pollutants, including microplastics, into waterways during snowmelt.
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.
Study of the presence of microplastic particles and heavy metals in street dust on the right side of Mosul city / Iraq

Global hotspots and trends in interactions of microplastics and heavy metals: a bibliometric analysis and literature review
This bibliometric review analyzed over 550 published studies on how microplastics interact with heavy metals in the environment. The research shows that microplastics can absorb heavy metals from surrounding water and soil, concentrating these toxic substances and carrying them into living organisms. This combined contamination is a growing concern for human health because microplastics may deliver concentrated doses of heavy metals into the body through food and water.
