Characterization of microplastics in storm water in Örebro, Sweden
AI summary Read the abstract
Researchers characterized microplastics in stormwater samples from Orebro, Sweden, measuring particle abundance, size distribution, morphology, and polymer types across multiple storm events. They found fibers and fragments dominated, with tire rubber particles also present, and observed variation in concentration with rainfall intensity and land use type. The study contributes data on stormwater as a microplastic transport pathway in a Swedish urban context.
Microplastic is a widespread pollutant in marine and fresh water systems. A major pathway by which microplastics end up in these systems is via storm water. Storm water is generated as precipitatio ...

Microplastics in a highway stormwater system: concentrations and variability during rainfall
AI summary Read the abstract
Researchers tested stormwater collected during rainfall at a Swedish highway and found microplastics, including tyre-related rubber particles, in every sample. Tyre particles made up about 41% of the total microplastics measured, confirming tyres as a major source, though concentrations varied widely and did not clearly relate to other measured pollutants like metals.
Stormwater runoff microplastics: Polymer types, particle size, and factors controlling loading rates
AI summary Read the abstract
Researchers characterized microplastics in stormwater runoff samples collected at urban outfall locations. The study identified 17 different polymer types across various storm events, with concentrations around 0.99 particles per liter for the 500-1000 micrometer size range, and found that rainfall intensity and land use were key factors controlling microplastic loading rates.
Temporal and spatial variations of microplastic concentrations in surface waters in Gothenburg, Sweden.
AI summary Read the abstract
Microplastic concentrations were measured across Gothenburg's urban surface waters over multiple seasons in 2017, characterizing spatial and temporal variation in plastic particles, fibers, and other anthropogenic particles. The study contributes to monitoring urban microplastic pollution in Scandinavian surface waters and identifies stormwater as a key pathway.
Microplastics and tyre wear particles in urban runoff from different urban surfaces
AI summary Read the abstract
Researchers measured microplastics and tire wear particles in stormwater runoff from roads, parking lots, and rooftops in Sweden. They found that road runoff carried the highest concentrations by far, with large variations between rainfall events. The findings highlight urban roads as a major source of microplastic pollution entering nearby waterways through stormwater.
Microplastics in stormwater runoff: case study Vitsippsbäcken
AI summary Read the abstract
This Swedish thesis quantified microplastic concentrations in stormwater runoff from a small urban catchment, finding that stormwater is a significant pathway for delivering microplastics to freshwater systems. Urban stormwater runoff is increasingly recognized as a major and underregulated source of microplastic pollution.
