The accurate simulation of meteorological conditions, especially within the planetary boundary layer (PBL), is of major importance for air quality modeling. In the present work, we have used the Weather Research and Forecast (WRF) model coupled with the chemistry transport model (CTM) CHIMERE to understand the impact of physics parameterizations on...
La qualité de l’air respiré par les usagers est de plus en plus affirmée dans les politiques publiques de transport dont les transports en commun en site propre (TCSP) constituent souvent des projets phares. Cet article s’attache à mesurer deux composantes importantes de la qualité de l’air urbain : les particules et les hydrocarbures aromatiques p...
Air filtration is a well-known approach to improve the automotive indoor air quality. The objective of the study reported here has been to develop an in-situ measurement protocol to assess the efficiency of particulate filtration systems. A large set of actions (air flow modeling, particle sampling and transport efficiency, etc.) has been carried o...
Regarding the great importance of a good working environment, in this research, ventilation systems installed in kitchens of restaurants were studied in order to avoid problems and to understand the key factors that can influence on the performance of the system. The results obtained were taken into account to provide some recommendations to a real...

In recent years, low-costs sensors have become one of the most widely reported topics in the field of air quality measurement. In fact, in comparison to other indicative methods such as diffusive samplers, sensors are able to supply near to real time air pollution measurements by electronic means. This would enable an air quality assessment based o...
The evaluation of aerosol processes which alter the size distribution of accidentally released nanomaterial particles in an indoor environment can provide size resolved exposure estimations, and subsequently contribute to a more comprehensive risk analysis on engineered nanomaterials (ENMs). In this work processed suspensions of TiO2 and SiO2 nanop...
Assimilation of observational data from ground stations and satellites has been identified as a technique to improve air quality model results. This study is an evaluation of the maximum benefit expected from data assimilation in chemical transport models. Various tests are performed under real meteorological conditions; the injection of various su...
Pour améliorer la modélisation de la formation des aérosols organiques secondaires (AOS) des feux de végétation dans les modèles de chimie transport, un nouveau mécanisme chimique est développé. Il représente l'oxydation des principaux COVs (ceux ayant des rendements en AOS élevés et des facteurs d'émissions élevés). Le modèle de qualité de l'air P...
