“Atmospheric pollution is very heterogeneous and can present fluctuations of 1 to 5 during the day, depending on the areas of the Paris region. » explains Jean-Baptiste Renard (Jean-Christophe Marmara/Le Figaro).
INFOGRAPHICS – A new map of small particles has been created using sensors installed on more than 400 electric vehicles in five years.</ p>
From an air pollution point of view, it is better to live and work in the southwest of Paris than in the northeast of the capital, and avoid being near the main roads, especially within a few hundred meters of the Center. ring road between Porte d'Orléans and Clignancourt. This could summarize the results of the original study on concentrations of small particles smaller than 2.5 micrometers (also called PM2.5, they are 40 times smaller than the diameter of hair).
“Atmospheric pollution is very heterogeneous and can present fluctuations of 1 to 5 during the day, depending on the areas of the Paris region. »explains Jean-Baptiste Renard, CNRS research director at the Laboratory of Physics and Chemistry of the Environment and Space in Orléans.
