CUBAIR: a prototype for purifying indoor air

CUBAIR : un prototype pour purifier l’air intérieur

Improving indoor air quality? That’s what the CUBAIR project aims to do. By developing a new treatment system, researchers have managed to significantly reduce fine particle concentration and nitrogen oxides.   An important reminder: indoor air is often more polluted than outdoor air. In addition to the automobile exhaust and …

Fine particles: how can their impact on health be better assessed?

fine particles

In order to assess the danger posed by fine particles in ambient air, it is crucial to do more than simply take regulatory measurements of their mass in the air. The diversity of their chemical composition means that different toxicological impacts are possible for an equal mass. Chemists at IMT …

Atmospheric reactive trace gases: low concentrations, major consequences

Despite only being present in very small quantities, trace gases leave their mark on the atmospheric composition. Since they are reactive, they may lead to the formation of secondary compounds such as ozone or aerosols that have a significant impact on health and the climate. IMT Lille Douai is a …

What are fine particles?

fine particles, Véronique Riffault, IMT Lille Douai

During peak pollution events, everyone is talking about them. Fine particles are often accused of being toxic. Unfortunately, they do not only come out during episodes of high pollution. Véronique Riffault, a researcher in atmospheric sciences at IMT Lille Douai, revisits the basics of fine particles to better understand what …
