This Wednesday September 18 was an opportunity for the various environmental players to come back to the issue of air quality
Elisabeth Borne, French Ministry of Environment, took advantage of National Air Quality Day to announce an improvement to the atmospheric air quality marker index. Indeed, this one did not take into account at all the fine particles (PM2.5) which are now measured by most of the organizations or companies responsible for checking the air quality.
This is a good thing because the finest particles are also the most harmful. Indeed, the smaller a particle is, the easier it can cross the various barriers of the respiratory system. However, we can note that while we spend most of our time indoors, there is relatively little regard for indoor air quality. Indoor air has more important consequences than outdoor air, insofar as it is usualy more polluted and we spend the majority of our time inside, whether it is our places of life, work or transport.
In addition, if it is indeed illusory to hope to clean the atmospheric air if not by attacking the sources of pollution such as, mainly, transport, industry or heating, the installation of depollution means inside is important. One because the east is polluted and is injected into the interior space. Two because our interiors on their own sources of pollution. These sources include cleaning products, furniture, paints. ADEME repeats loudly that it is necessary to ventilate, but what can be the benefit of aeration in a polluted city?
In addition, microbiological pollution is scarcely reported in the confined spaces that constitute our schools, our nurseries, our retirement homes, our offices. These spaces are places of concentration of biological pollutants that we disseminate with each of our movements, with each of our breaths.
