Air quality levels across southwestern France have plummeted to hazardous levels on Wednesday, July 29, as intense wildfires continue to blanket the Gironde and Landes departments in toxic smoke, regional environmental authorities warned.
reported that daily air quality indices across the impacted zones have fallen between "very poor" and "extremely poor".
The agency attributed the severe ecological degradation directly to active forest fires, which have flooded the atmosphere with dangerous concentrations of fine particulate matter, including PM2.5 and PM10 particles. These fine suspended particulates pose significant respiratory health risks as they penetrate deep into lungs and cardiovascular systems.
Unseasonably high temperatures and intense sunlight across the region are accelerating chemical reactions in the atmosphere, driving up ozone pollution alongside fire-generated soot and ash.
