Wildfire smoke from Belgium affects air quality in eastern France

Smoke from major wildfires in the Hautes-Fagnes natural park in Belgium and the Ardennes is traveling hundreds of kilometers, causing degraded air quality across parts of eastern France. Residents in regions including Moselle, Bas-Rhin, and the Ardennes have reported strong burning odors and a visible haze in the sky.

Atmo Grand Est has triggered information and recommendation procedures due to high concentrations of PM10 particles. In some areas, particle levels reached 300 micrograms per cubic meter, significantly higher than the typical 20 micrograms per cubic meter seen during winter heating seasons. Officials note that these particles include organic compounds from incomplete combustion which can be harmful to respiratory health.

Health authorities recommend that residents keep doors and windows closed during periods of heavy smoke and only ventilate when conditions improve. It is advised to limit outdoor activities, reduce intense physical exercise, and avoid adding indoor pollutants like candles or incense. Vulnerable groups, including children, the elderly, and those with respiratory or cardiovascular issues, are urged to limit exposure.
