The lecture “Air Pollution: How Chemistry Can Help Us See More Clearly,” presented by Jean-Luc Besombes, Professor atthe Laboratory of Molecular and Environmental Chemistry(LCME),Faculty of Sciences and Mountain Studies,will take place on Tuesday, December 12, at 6:00 p.m. at the USMB Administration Building in Chambéry.
It will also take place on Thursday, December 14, at 6:00 p.m. in Annecy (La Turbine Sciences, Place Chorus, Cran-Gevrier 74960 Annecy).
ABOUT THE CONFERENCE
Episodes of air pollution are receiving increasing media attention and are stirring public concern. Ozone, nitrogen dioxide, and fine particulate matter are just a few examples of the compounds that degrade the air we breathe. Air pollution thus takes many forms and is characterized by phenomena that vary significantly depending on the season and the region. The sources of this pollution are numerous, and while emissions from human activities contribute significantly to the deterioration of air quality, natural processes also play a role in this phenomenon. While our understanding of the dynamics of gaseous pollutants has advanced significantly in recent decades, the mechanisms of particulate pollution still require further clarification. We will explore, in particular, how analyzing the chemical composition of these particles can help us better understand their origins, their behavior, and consequently their impacts.
