Why these pollution peaks during heat waves?
Tony Renucci : “During heat waves or just during very hot weather, high temperatures increase air pollution.ozone. This atmospheric pollutant is a gas that is formed by the combination of pollutants: volatile organic compounds (VOC) and nitrogen oxide, the latter being emitted mainly by road traffic.
What consequences do these ozone peaks have for health?
Tony Renucci : “Ozone is an irritant gas, especially for the respiratory tract. Occasional short-term exposure to this pollutant leads to irritation of the eyes or the respiratory tract, asthma attacks, exacerbations of cardiovascular and respiratory disorders .
It is vulnerable people (infants, children, pregnant women, people over 65) and sensitive people (cardiac, asthmatics, bronchitis, respiratory failure) who are the most affected by air pollutants. Any signs that you are suffering from exposure to this pollution? You have a scratchy or itchy throat, sneezing, difficulty breathing.”
What to do during pollution peaks to prevent adverse health effects?
Tony Renucci : “You can be warned (ie) of a peak in ozone pollution in your region or town by consulting the ATMO index on official sources of information: airparif for Ile-de-France and ATMO for each region. The first thing to do in case of ozone pollution peak is to help reduce ozone formation by avoiding driving and using public transport. During ozone pollution peaks, if you know you are particularly sensitive to the effects of air pollution (we knows that genetically some people have trouble detoxifying pollutants), it’s best to stay home if you don’t have an essential trip to make.
For others, it is recommended not to practice physical activity outdoors. Physical activity increases the rate of breathing, causing particles to penetrate deeper into the bronchi. “We breathe in 10 times more pollutants when we play sports,” explains the Director of the Respire association. It is necessary to favor the outings of children and the most fragile people before 10 a.m. and after 5 p.m. The ozone level are indeed weaker at these times”.
