Air

Air pollution affects the entire population. The levels of pollutants found in the atmosphere are linked to health risks, and any reduction in exposure to these pollutants would be beneficial.

Our missions

  • Coordinate the Air and Health Monitoring Program (Psas) at the national and regional levels to generate knowledge on the links between air pollution and health and provide decision-making tools

  • Inform public authorities, healthcare professionals, and the general public about the health impacts of air pollution

Air pollution: short-term effects

The Public Health France PSAS has been a pioneer in the field of monitoring the short-term effects of air pollution and has contributed to international developments in this area. 

So-called multicenter studies (covering multiple cities or metropolitan areas) form the basis for monitoring the short-term effects of air pollution. Robust and grounded in several years of data, they rely on statistical methods that enable the establishment of day-to-day links between pollution and health indicators. In these studies, numerous factors (temperature, seasonal epidemics, etc.) are taken into account to ensure that only the effects attributable to pollution are attributed to it.

Today, the 20 French urban areas participating in the program—including two overseas territories—allow for the diversity of air pollution in France to be taken into account. Between 2007 and 2010, while none of these metropolitan areas exceeded the European regulatory limit (40 μg/m³ as an annual average for PM10), only Dijon met the World Health Organization’s guideline value (20 μg/m³).

Studies conducted since 1997 have mostly concluded that there has been an increase:

  • on the one hand, in mortality and hospitalizations due to cardiovascular causes, attributable to fine particulate matter (PM10 and PM2.5);

  • and, on the other hand, in mortality and hospitalizations due to respiratory causes, attributable to ozone (O3) in the summer.

Recent findings show that a 10 µg/m³ increase in PM10 levels on a given day and over the preceding five days is associated with a 0.5% increase in non-accidental mortality. This increase is higher among people aged 75 and older (+1.04%). The effects on mortality are more pronounced in the summer.
