Comprehensive dataset of magnetic, chemical, mineralogical, microplastic, and electrical (EIS) properties of urban road dust from Warsaw and Vienna (Grant Sonata National Science Centre, Poland project number 2021/43/D/ST10/00996 Sylwia Dytłow)
AI summary Read the abstract
Scientists collected dust samples from streets in Warsaw and Vienna to measure what's actually in the grime we walk through every day, including tiny metal particles, microplastics, and other pollutants. This kind of detailed data helps researchers understand how much of this potentially harmful material builds up in cities, which is an important first step toward figuring out what it might mean for our health down the road. Note that this dataset itself doesn't draw health conclusions, it's the raw information other studies will likely use to investigate those questions.
This dataset contains comprehensive physicochemical, magnetic, chemical, and microplastic data from two road dust sampling campaigns conducted in 2024 and 2025 across Warsaw and Vienna. It features...

"Dust in the Fire" : First Investigation of Microplastics in Urban Road Dust via Magnetic Separation of Strong and Weak Components in Vienna, Austria
AI summary Read the abstract
Scientists found tiny plastic particles mixed with magnetic materials in street dust from Vienna, Austria - the first study of its kind in that city. Road dust containing these microplastics can become airborne and be inhaled by people, or wash into waterways where it pollutes the environment. This research helps us better understand how microplastics spread through urban areas and potentially affect human health through breathing contaminated dust.
Microplastic Distibution and Magnetic Susceptibility in Size-Fractionated Road Dust from Warsaw: Environmental Implications.
AI summary Read the abstract
Researchers collected road dust from Warsaw and analysed microplastic distribution and magnetic susceptibility across five particle size fractions (0.2 to 1 mm), finding that MP abundance and magnetic properties vary with size fraction, with implications for understanding road dust as a source of microplastic pollution in urban environments.
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.
AI summary Read the abstract
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.
Magnetic association of microplastics in urban road dust: Size distribution and ecological risk.
AI summary Read the abstract
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.
Examining magnetic susceptibility as a proxy for microplastic pollution in granulometric fractions of road dust: A case study in Warsaw, Poland
AI summary Read the abstract
Researchers in Warsaw, Poland investigated whether magnetic susceptibility measurements could serve as a quick proxy for detecting microplastic pollution in road dust. Using laser direct infrared imaging and magnetic analysis, the study assessed the relationship between magnetic properties and microplastic concentrations across different particle size fractions of road dust.
