, On peut ameliorer considerablement les performances de la technique de la fluorescence X classique par la reflexion totale. Nous appliquons cette derniere a l'etude de la distribution granulometrique des elements toxiques, Indesirables et PM10 dans les aerosols de la ville d'Antananarivo. L'echantillonneur DICHOTOMOUS est utilise pour les prelevements d'echantillons. On peut obtenir deux types d'aerosols : les particules respirables ou les particules fines PM2•5 (diametre aerodynamique...
