Résumé
Metallic emissions (13 metallic species) from 12 different metallic roofing materials, belonging to five families (zinc, copper, lead, steel, and aluminium) have been assessed over a 14 month period on two test beds in Paris conurbation. Based on this data, annual metal flows per square meter of material are calculated and the different materials are classified according to their polluting potential. A simple model has been developed to calculate metal emissions at different temporal and spatial scales, taking into account the exposure conditions (duration, rainfall depth, roof characteristics) and validated at real roof scale.
