ClearAn 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.
Pollution and health risk assessment of co-existing microplastics and heavy metals in urban dust of Riyadh city, Saudi Arabia
Researchers found microplastics and heavy metals in all 20 urban dust samples collected from indoor and outdoor locations in Riyadh, Saudi Arabia, with toddlers estimated to inhale the most microplastic particles relative to their body weight. Fragment-shaped particles were the most common, and heavy metals including lead and chromium were found alongside the microplastics. The co-occurrence of microplastics and heavy metals in household and street dust means that people, especially young children, face daily exposure to both pollutants through the air they breathe.

First comprehensive assessment of microplastics in urban street dust of Eastern Saudi Arabia: abundance, traits, and health risks
Researchers conducted the first comprehensive assessment of microplastic contamination in street dust from two major cities in eastern Saudi Arabia. Microplastics were found in all 58 sampling sites, with polyethylene, PET, and polypropylene being the most abundant polymers, alongside concerning levels of high-toxicity polymers like PVC and polystyrene. The study found that children face substantially higher estimated daily microplastic intake than adults, particularly in residential and recreational 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.
Evidences of Microplastic in Air and Street Dust: A Case Study of Varanasi City, India
Researchers measured microplastics in air and street dust samples from multiple sites in Varanasi, India, finding plastic particles in all samples including suspended and settled dust. The study adds to evidence that urban air and dust are important but underappreciated sources of human microplastic exposure.
Mapping of heavy metal contamination associated with microplastics marine debris - A case study: Dubai, UAE
XRF analysis of 480 microplastic pieces extracted from Dubai beach sediments identified 14 heavy metals including five EPA priority pollutants (Cr, Ni, Cu, Zn, Pb) sorbed onto PE and PP microplastics, demonstrating microplastics serve as carriers for toxic metals in coastal marine environments.
Magnetic association of microplastics in urban road dust: Size distribution and ecological risk.
Scientists found that tiny plastic particles called microplastics are heavily concentrated in urban road dust, especially the smallest particles that can easily become airborne. The magnetic particles in this dust contain up to seven times more microplastics than non-magnetic particles, which matters because we breathe in this dust daily when walking, driving, or when wind stirs it up. This research helps us better understand how much plastic pollution we're exposed to in cities and where it comes from.
