| The air pollution, that stinks and that kills |
|
After a period of relative calm, France recorded again in January numerous alerts in the air pollution in Ile-de-France, in the East, on the West and in region Rhône-Alpes. This pollution takes a quite particular relief after the publication of the alarming study of the INVS which confirms the existence of short-term links, between this air pollution and the mortality rates.
A study published on Tuesday in the weekly epidemiological Bulletin ( BEH) of the national Institute of the sanitary surveillance ( INVS) underlines again the existence of a "significant" link between the number of deaths and the exhibition(exposure) in 3 pollutants of the air(sight): the nitrogen dioxide ( NO2), the ozone ( O3) and the PM-10 (particles of diameter lower than 10 microns). Synthesis of two reports(connections) published in 2006 and 2008, the study was realized from the epidemiological data collected between 2000 and 2004, stemming from 9 French cities representing a population of 11 million inhabitants, representative in term of climate and pollution. More risks of deathIn France, according to the INVS, the evolution of the levels and the chemical composition of the urban atmospheric pollution justified an updating, for period 2000-2004, results obtained within the framework of the Program of surveillance air(sight) and health ( Psas) on the short-term relations between atmospheric pollution and mortality and hospitable(hospital) admittances. The analysis based on temporal series consisted in connecting the short-term variations of indicators(informers) of the health (mortality and hospitalizations) to those of the indicators(informers) of exhibition(exposure) in the atmospheric pollution (NO2, O3 and PM10). The relative risks were estimated for each of 9 studied cities then an analysis combined by these results was realized. The risk of death any causes or for cardiovascular and cardiac causes is significantly associated with all the studied indicators of pollution. Cardiovascular disorders The hospitalizations for cardiovascular causes are so significantly associated with the levels of the atmospheric pollution with the exception of the ozone. These two studies confirm the existence of significant links between the levels of atmospheric pollution usually observed and the indicators of health. They also allowed to obtain useful valuers for the realization of evaluation of the sanitary impact of the urban atmospheric pollution in France. |
