Wildfire smoke: a frequently underestimated health risk
Wildfires are often seen as a danger only for people living close to the flames but wildfire smoke can travel across regions, countries and even continents, worsening the air quality of down-wind communities with both physical and psychological impacts, including for people who live far from the fire itself. In a changing climate, the risk of wildfires is increasing; the huge fires in the WHO European Region and beyond this summer are a reminder that the dangers of wildfires come not only from the flames but also from smoke. Increased air pollution Cars burn in Spain’s Sierra Oeste region, less than an hour from Madrid. Wildfire smoke is a complex mixture of gases and very small particles, released when trees, vegetation, buildings and other materials burn. When wildfires affect urban or industrial areas, the risk of additional noxious content increases. Fine particulate matter (known as PM2.5) is one of the main concerns, as these tiny particles can be breathed deep into the lungs and enter the bloodstream.
