Impact of the chemical environment on health (IMPECS)
Research unit - ULR 4483
The scientific program of our laboratory aims to better understand the reactional complexity of lung tissues exposed to chemical compounds present in the air, to explain the inequalities of individuals with respect to these substances, to better understand the levels of risk and, consequently, to better predict and better prevent the impact of this environment on respiratory health.
Overall, our research project addresses two major challenges: (1) first, the identification of early markers of exposure or effects of aerocontaminants, as well as factors of susceptibility to these substances or of predisposition to environmental respiratory diseases; (2) second, the evaluation of the relevance of these biomarkers in different human populations (general population or patients with chronic bronchopulmonary pathology.
