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

, , ,
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…

If the ocean were a country, it would be the world's 7th-largest economic power, according to a report by the WWF, and the wealth it produces could double by 2030. The Brittany region, at the forefront of marine science and technology research,…

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…
VOC, Volatile organic compound

What is a volatile organic compound (VOC)?

, , , ,
Pollution in urban areas is a major public health issue. While peaks in the concentration of fine particles often make the news, they are not the only urban pollutants. Volatile organic compounds, or VOC, also present a hazard. Some are carcinogenic,…
