Comparison of the in vivo genotoxicity of electronic and conventional cigarettes aerosols after subacute, subchronic and chronic exposures.

Tobacco smoking is classified as a human carcinogen. A wide variety of new products, in particular electronic cigarettes (e-cigs), have recently appeared on the market as an alternative to smoking. Although the in vitro toxicity of e-cigs is relatively well known, there is currently a lack of data on their long-term health effects.

Study of in vitro and in vivo genotoxic effects of air pollution fine (PM) and quasi-ultrafine (PM) particles on lung models.

Air pollution and particulate matter (PM) are classified as carcinogenic to humans. Pollutants evidence for public health concern include coarse (PM) and fine (PM) particles. However, ultrafine particles (PM) are assumed to be more toxic than larger particles, but data are still needed to better understand their mechanism of action.
