Urban soil pollution in Türkiye: a review of potentially toxic elements, polycyclic aromatic hydrocarbons, and microplastics in major cities
This review summarizes the state of urban soil pollution in major Turkish cities, focusing on toxic metals, polycyclic aromatic hydrocarbons, and microplastics. Researchers found that cadmium and lead frequently exceeded national soil quality limits, microplastics were most abundant in parks and along roadsides, and pollution hotspots concentrated around industrial areas and traffic corridors. The study highlights the need for more systematic monitoring to develop effective soil management and remediation strategies.
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.
Study of the presence of microplastic particles and heavy metals in street dust on the right side of Mosul city / Iraq
Researchers analyzed microplastic particles and heavy metal concentrations in street dust samples collected from residential, commercial, and industrial areas on the right bank of Mosul city in Iraq. The study assessed the combined pollution burden and potential environmental health risks associated with microplastic and heavy metal co-contamination in urban street dust.
Assessment of Heavy Metal Exposure in Soils of Ihwrekreka Communities, Delta State, Nigeria
Soil samples from crude oil-polluted communities in the Ihwrekreka area of Nigeria's Niger Delta were analyzed for heavy metal concentrations using inductively coupled plasma optical emission spectrometry. The study assessed potential health risks to residents from exposure to chromium, nickel, lead, cadmium, and other metals elevated by decades of petroleum contamination.
Solid Waste Disposal and Extent of Selected Heavy Metals in Fadama Area of Sokoto City, Nigeria
This study assessed solid waste disposal practices and heavy metal concentrations in the Fadama area of Sokoto city, Nigeria, finding elevated levels of multiple metals in soil samples attributable to improper waste dumping, with implications for public health in communities living near informal disposal sites.
Heavy metal mobility and bioavailability in sediment fractions of major tourist beaches on the south-west coast of India: Implications for coastal ecological health
Researchers applied sequential extraction to sediments from four tourist beaches in Kovalam, India, characterizing the mobility and bioavailability of seven heavy metals across five geochemical fractions, finding copper and cadmium at high pollution and enrichment levels and identifying significant non-carcinogenic health risks for children from lead, chromium, zinc, and copper at all beaches.
An Investigation of Microplastic Occurrence and Heavy Metals Concentrations in Street Dust on the Left Side of Mosul City, Iraq
Street dust collected from Mosul, Iraq contained microplastic particles across residential, commercial, and industrial zones, alongside elevated concentrations of heavy metals. The co-occurrence of microplastics and toxic metals in urban dust is a concern for human health, as both can be inhaled or ingested by city residents, particularly children.
Characterization of microplastic, metals associated and ecological risk assessment in the topsoil of shiraz metropolis, south west of Iran
Researchers surveyed topsoil across the city of Shiraz, Iran and found microplastics in all sample types, with urban soils containing roughly three times more particles than industrial or agricultural soils. Fragments and small particles between 100 and 250 micrometers were the most common forms detected. The study also found that metals like lead, zinc, and copper tend to accumulate on microplastic surfaces, potentially increasing the ecological risk these particles pose.
Contamination, Toxicity and Ecological Risk Assessment of Heavy Metals in Surface Sediments of Coastal Areas of Bushehr Province: A Systematic Review Study
This systematic review of studies from 2012-2020 found that coastal surface sediments in Bushehr Province, Iran, contain heavy metals at levels posing moderate to high ecological risk, with nickel, chromium, and cadmium identified as the primary contaminants from petrochemical and industrial sources. The pollution levels exceeded safe thresholds in several coastal areas. Coastal sediment contamination with heavy metals often co-occurs with microplastic pollution, and microplastics can adsorb and concentrate these toxic metals, potentially increasing their bioavailability to marine organisms.
Distribution characteristics and integrated ecological risks evaluation modelling of microplastics and heavy metals in geological high background soil
Researchers investigated the co-occurrence of microplastics and heavy metals in high geological background soil in Qianxi, China, and developed a new model for evaluating their combined ecological risk. They found elevated cadmium levels alongside significant microplastic contamination, with different crop rotation patterns influencing pollution distribution. The study proposes a two-dimensional index for assessing the joint environmental risks of microplastics and heavy metals in agricultural soils.
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.
Pollution and health risk assessment of heavy metals in the soil around an open landfill site in a developing country
