Description
Minh Tri Truong and colleagues map toxic metals in road dust across seven mid-size cities in the eastern United States in a 2026 study. Dust was tested for eleven potentially toxic elements, including copper, zinc, arsenic, cadmium, and lead. Statistical methods were used to trace each element to likely sources and to judge health risk.
About one third of the hazardous load was linked to coal burning and past pesticide use, while two thirds came from city sources such as vehicle wear, waste burning, and industry. The most hazardous metals tended to cluster in lower-income areas, even where their overall levels were modest. The study gives city officials a source-by-source picture for street cleaning, traffic control, and soil safety work.
