Toxic Pollutants in Urban Fires
Urban fires release a complex mix of toxic pollutants, including metals like lead, volatile organic compounds such as benzene, and hazardous substances like PFOS. These contaminants found in smoke and ash pose significant health risks, as they can be inhaled or settle into soil and water, affecting the broader environment. The persistence of these pollutants in soil and groundwater makes them especially problematic, as some do not break down over time, contributing to long-term contamination issues. Dioxins, which are produced during fires, further exacerbate the situation by adding to the already dangerous mix of chemicals released into affected areas.
