Les métaux dans les particules atmosphériques : les isotopes peuvent-ils aider à discriminer les pôles d'émission potentiels ?

Abstract : The study of atmospheric pollution by the aerosols includes scientific questions, resulting from both local (air quality, health impacts) and global (contaminant inputs into ecosystems, impact on global change) problems. The fine particles, especially PM2,5, represent a major objective for authorities, at the European scale, as well as at the French one, following the Grenelle Environment Forum. Their role as vectors of potentially toxic heavy metals (such as lead or cadmium) has only been studied since relatively recently. This article shows that the recent use of metal isotope systematics, mercury, cadmium and zinc, proves to be a reliable discrimination tool for tracking pollution sources of atmospheric particles. This will ultimately open the door for the application of these isotope systematics as tracers of sources of particulate atmospheric pollution.
