Das Ersticken von Waldbränden ist weitaus gefährlicher als bisher angenommen, wobei die Zahl der Todesopfer durch kurzfristige Exposition gegenüber feinen Partikeln um 93%unterschätzt wird.

>“Previously, people assumed the same toxicity for wildfire particles and all particles,” said Prof Cathryn Tonne, an environmental epidemiologist at the Barcelona Institute for Global Health (ISGlobal) and co-author of the study.

>“Our paper shows evidence that – although it happens less often – the health impact for the same amount of particles is stronger for wildfire particles,” she added.

>Using models that account for an expected lag in deaths, they found exposure to wildfire smoke increased the risk of death in the following week.

>For every extra microgram of PM2.5 fouling 1 cubic metre of air, they found that all-cause mortality rose by 0.7%, respiratory mortality went up by 1% and cardiovascular mortality rose by 0.9%.
