Air pollution in a nutshell


Why does the air arouse our attention?

We often hear about peak pollution or simply pollution. Indeed, the air we breathe is not always of good quality. Especially in urbanized areas as well as in mountain valleys.

The air we breathe is considered responsible for 48,000 deaths in France.

There is a lot of thought about the impact of pollution on our health during pollution peaks, but we must know that it is the regular and long-term pollution, even at moderate levels of pollution, which has the greatest impact on the health.

What is polluting the air?

Several pollutants alter the quality of our air. We have three particularly troubling ones today: fine particles, nitrogen dioxide and tropospheric ozone.

Where do the pollution come from?

The first sources of pollution are varied:

industries (gaseous releases, dusts, etc.) that account for 80% of sulfur dioxide emissions;
agriculture (fertilizers, pesticides, livestock manure, etc.) responsible for 97% of ammonia emissions;
heating (wood, oil, etc.) responsible for more than 90% of fine particulate emissions in the residential sector;
burning of green waste. The fine particles emitted by 50 kg of plants burned in the open air are equal to those emitted by about 13 000 km traveled by a recent car;
transport (mainly road traffic), which is responsible for about 90% of the emissions of primary particles and nitrogen oxides related to road transport come from diesel vehicles.
Air pollution can also come from natural phenomena such as volcanic eruptions, fires or lightning ... but in much smaller quantities!

Focus on transport

In urban areas, where almost 40% of daily trips by car are less than 3 km away, road traffic is a very important source of pollution. Indeed, these trips are 2 times more polluting than a trip of greater distance (overconsumption of fuel when the engine is cold, frequent stops and restarts, etc.).

How can we change things?

By taking public transportation, cycling, skating or using one's feet (30 minutes of moderate daily physical activity are good for your health!);
being tempted by carpooling if the car is absolutely necessary;
if you have the license, pay attention to your driving: slower, less brutally it is good for the planet, because it limits polluting emissions!
