Environmental pollutants such as microplastics have become a major concern over the last few decades. We investigated the presence, characteristics, and potential health risks of microplastic dust ingestion. The plastic load of 88 to 605 microplastics per 30 g dry dust with a dominance of black and yellow granule microplastics ranging in size from 250 to 500 μm was determined in 10 street dust samples using a binocular microscope. Fluorescence microscopy was found to be ineffective for… Expand
Assessment of Microplastics in Roadside Suspended Dust from Urban and Rural Environment of Nagpur, India
Contamination from microplastics is a growing concern around the globe that materialized over the last few decades. Road dust is one of the main contributors of microplastics in an urban environmentExpand
Prevalence and characteristics of microplastics present in the street dust collected from Chennai metropolitan city, India.
TLDR
Assessment of microplastic pollution rampant in street dust, especially in coastal cities as Chennai, is a dire need as it pertains to the concerns of human health and escape into the marine environment. Expand
Distribution and potential health impacts of microplastics and microrubbers in air and street dusts from Asaluyeh County, Iran.
While the distribution and effects of microplastics (MPs) have been extensively studied in aquatic systems, there exits little information on their occurrence in the terrestrial environment and theirExpand
Quantification of selected microplastics in Australian urban road dust.
TLDR
Microplastics concentrations in road dust demonstrated a significant relationship with the volume of vehicles, suggesting traffic, as a proxy for human movement, is associated with increased microplastic concentrations in the built environment. Expand
Widespread distribution of PET and PC microplastics in dust in urban China and their estimated human exposure.
TLDR
Indoor dust is a non-negligible source of human exposure to MPs, accounting for a geomean daily intake of 17,300 ng/kg-bw of PET MPs in children, and polyester was identified as an important component in MPs from dust. Expand
Investigation of microrubbers, microplastics and heavy metals in street dust: a study in Bushehr city, Iran
This study aimed to (1) investigate microrubbers (MRs) for the first time and identify microplastics (MPs) in street dust, (2) determine the physicochemical and mineralogical characteristics andExpand
Plastic additives as tracers of microplastic sources in Japanese road dusts.
TLDR
Road markings are a significant source of microplastics in Japanese road dust, and that additive profiles in plastic samples may be suitable tracers for determining the sources of microPLastics in road dust. Expand
Airborne microplastics: a review study on method for analysis, occurrence, movement and risks
TLDR
A comprehensive overview of current knowledge or information regarding microplastics in air is provided, identifying gap in knowledge, and giving suggestions for future research is provided. Expand
Microplastics and Nanoplastics Occurrence and Composition in Drinking Water from Akureyri Urban Area, Iceland
Microplastics as a potential health and environmental problem has gained increasing attention recently. Microplastics are defined as plastic pieces smaller than 5 mm in diameter, and there are manyExpand

This study investigates the microplastic contamination of both urban compartments (wastewater and total atmospheric fallout) and surface water in a continental environment (Greater Paris, France).Expand
Accumulation of microplastic on shorelines woldwide: sources and sinks.
TLDR
It is shown that microplastic contaminates the shorelines at 18 sites worldwide representing six continents from the poles to the equator, with more material in densely populated areas, but no clear relationship between the abundance of miocroplastics and the mean size-distribution of natural particulates.

Microplastic pollution in the surface waters of the Laurentian Great Lakes.
TLDR
The presence of microplastics and coal ash in these surface samples, which were most abundant where lake currents converge, are likely from nearby urban effluent and coal burning power plants. Expand
Microplastics and potentially toxic elements in coastal sediments of Iran's main oil terminal (Khark Island).
TLDR
The key role of microplastics as a "potential contaminant vector" for other types of pollutants was confirmed and a relatively good significant linear relationship exists between microplastic quantities and potentially toxic element/polycyclic aromatic hydrocarbon concentrations in coastal sediments. Expand
Occurrence and spatial distribution of microplastics in sediments from Norderney.
TLDR
The spatial distribution of small potential microplastics (SPM) in beach sediments was studied on a 500 m stretch of the North Sea island of Norderney and the occurrence of SPM did not correlate with that of VPD. Expand
Health risk implications of potentially toxic metals in street dust and surface soil of Tehran, Iran.
TLDR
Calculated Hazard Index (HI) suggests ingestion as the most important pathway for the majority of PTMs in children and dermal contact as the main exposure route for Cr, Cd and Sb for adults and fractionation pattern of elements revealed Pb as the sole element that bears potential health risk in street dust and surface soil.

Characterization of heavy metal particles embedded in tire dust.
TLDR
It is concluded that tire dust consists not only of the debris from tire wear but also of assimilated heavy metal particles emitted from road traffic materials such as brake lining and road paint. Expand

TLDR
The lack of knowledge on microplastic in soil is surprising given that the occurrence of larger plastic fragments in soils per se is nothing new, and has in fact been a trait used to describe urban soils or Technosols. Expand
