Although aerosols are not alone in the "fine particle" category, every year 391,000 people in EU countries die from air pollution, and it causes 1.1 million premature deaths in India and China.

Other possible causes

Aerosoloù

Smoke from wildfires has been shown to carry toxic particles.


Aerosoloù

Buildings emit few aerosols directly. The only significant emissions are chimney fires. In Chamonix, 85% of the fine particles present in the atmosphere come from wood heating.


Aerosoloù

Local pollution due to exhausts pipes is one of the main motivations to promote electric cars, far more than climate change. But EV are responsible for CO2 emissions due to power generation. These emissions depend a lot on the country where the car is rolling. See the file about it.


Aerosoloù

Spraying crops does result in aerosols and air pollution, but not to the same extent as incomplete combustion from power plants.
