Abstract
Reducing environmental health inequalities has become a major focus of public health efforts in France, as evidenced by the French action plans for health and the environment. To evaluate environmental inequalities, routine monitoring networks provide a valuable source of data on environmental contamination, which can be used in integrated assessments, to identify overexposed populations and prioritize actions. However, available databases generally do not meet sufficient spatial representativeness to characterize population exposure, as they are usually not assembled for this specific purpose. The aim of this study was to develop geoprocessing procedures and statistical methods to build spatial environmental variables (water, air, soil, and food pollutant concentrations) at a fine resolution, and provide appropriate input for the exposure modelling. Those methods were designed to combine in situ monitoring data with correlated auxiliary information (for example, atmospheric emissions, population, and altitude), in order to better represent the variability of the environmental compartment quality. The MODUL’ERS multimedia exposure model developed by INERIS (French Institute for industrial Environment and Risks) was then used to assess the transfer of substances from the environment to humans, through inhalation and ingestion pathway characterization. We applied the methodology to a carcinogenic Polycyclic Aromatic Hydrocarbon substance, benzo[a]pyrene(B[a]P), to map spatialized exposure indicators, at the national scale. The largest environmental contribution corresponded to the ingestion pathway. Data processing algorithms and calculation of exposure will be integrated into the French coordinated integrated environment and health platform PLAINE (PLteforme intégrée d’Analyse des INégalités Environnementales) which has been developed to map and analyze environmental health inequalities.
Highlights
Environmental health inequalities refer to the general differences in environmental health conditions
The present study aims to harmonize the data coming from different sources and explore spatial statistical methods to improve the limited resolution of measurements, in the three environmental compartments, and to set the basis for a robust multimedia exposure assessment due to Benzo[a]pyrene (B[a]P), in France
B[a]P concentrations under the detection limit were estimated through the multiple imputation method
Summary
Environmental health inequalities refer to the general differences in environmental health conditions. It refers to the recognition of disparities between territories or populations concerning environmental exposure. People are more likely to be exposed to the negative effects of air, soil, or water pollution. This issue has been identified as a priority for French policies, as evidenced by the emergence of the French plans for health and environment. The third plan (2015–2019) highlights the need to establish a methodology to identify and reduce environmental. Res.
