The article “Examining magnetic susceptibility as a proxy for microplastic pollution in granulometric fractions of road dust: A case study in Warsaw, Poland” (https://doi.org/10.1016/j.jhazmat.2025.138493) with supplementary materials and supporting data.

Summary

This article and dataset examine whether magnetic susceptibility measurements of road dust granulometric fractions can serve as a rapid proxy indicator for microplastic pollution levels in Warsaw, Poland. Developing fast, indirect monitoring proxies for road dust MPs is important because roads are a major source of tire-wear microplastics and fragmentation particles that wash into waterways and enter the food chain.
