π¬ Toxic metals still in city road dust
Scientists found that road dust in seven eastern US cities contains toxic metals from old factories and decades-old pesticides. Researchers sampled dust in Trenton, Wilmington, Richmond, Raleigh, Greensboro, Charleston, and Augusta during August 2025. One-third of the hazardous metal pollution originated from older sources like coal combustion. Children face a significantly higher exposure risk compared to adults across all surveyed areas. This research highlights the need to monitor legacy contaminants near urban communities. π§
