In December, France had its longest pollution peak for at least ten years. The concentration of fine particles remained at a level 4 to 5 times higher than usual. This phenomenon was due to a seasonal increase in particulate emissions, particularly dependent on heating. The meteorological conditions, favourable to the pollutants maintenance near the ground, reinforced it.

Mortality increase due to heat waves has been extensively studied. For example, it is estimated that 70,000 additional deaths occurred during 2003 heatwave in Europe. The increasing frequency and intensity of heatwaves projected for the coming century is an important health concern.

Air ionization is known for decades, as is the correlation between negative ions and air quality: the more negative ions in the air, the less polluting particles. In urban environment, and especially inside buildings, negative ions are missing. To assess the nocivity of this lack of negative ions, scientists have studied the influence of air ionization on our physiology. Here are some picks from their research results.
