Fine particulate emission sources identification in the atmosphere of São paulo

The contribution of this work was related to the evaluation ofthe emission sources profile for the fine particles concentration, mainlythe role of vehicular emission in Sao Paulo atmosphere. During a year,starting in August 2007, daily 24 hours samples were collected. Theparticles were characterized for its mass concentration, elementalspeciation by means of X-Ray fluorescence analysis, ionic compositionand Black Carbon mass concentration. Receptor modeling was appliedas the methodology for the identification of fine particles pollutantssources.
