Abstract
Fossil fuel and biofuel emissions of gases and particles in Africa are expected to significantly increase in the near future, particularly due to rapid growth of African cities and megacities. Air quality degradation is then expected with important consequences on population health.
In the frame of the OMP pole of Environment and Health and through the AMMA, POLCA, IDAF, MOUSSON programs, we are constructing a new integrated methodology to study the relations between emissions, air quality and health impact. This approach includes: (1) combustion emission characterizations; (2) experimental joint determination of gas concentrations and aerosol chemistry from ultrafine to coarse aerosol size fractions and health factors. In the frame of POLCA experiments, some individuals representative of a long term exposure on the measurement site are tested (blood and respirometry analysis; (3) integrated environmental and health modeling. Exposures obtained from our multiscale and multispecies environmental modeling will be associated to a new dedicated aerosol/gas module developed for intake, uptake and clearance of gases and particles in the respiratory system.
In this work, we present the first results that illustrate the construction of such a methodology: i) a new African inventory of fossil fuel and biofuel emissions adapted to regional specificities has been constructed for the years 2000-2005 and 2030; ii) an overview of short term and intensive campaigns in Cotonou (AMMA, 2005), Bamako and Dakar (POLCA, 2007-2009), Ouagadougou (MOUSSON 2007-2009) will document atmospheric pollution of Western African cities. Tentative comparisons between such experimental results and modeling results issued from ORISAM-TM5 model will be proposed.
In the frame of POLCA experiments, in vitro studies have been conducted from sampled filters to correlate aerosol concentrations to oxidative stress and cells inflammatory processes. Preliminary results will be tentatively presented for Bamako experiment.
