Microplastics, often found in stormwater runoff, pose a significant threat to water quality as they enter various water sources during rainfall.
While these pollutants primarily originate from urban areas, current datasets tend to concentrate on marine and coastal environments, leaving a gap in understanding urban impacts.
The introduction of a standardized runoff dataset could provide better insights into the prevalence and distribution of microplastics in urban settings, potentially guiding future environmental policies.
