In order to determine the speciation of lead in ambient air dust, a combination of two complementary levels of investigation is used. The first one consists in a quantitative bulk analysis of the samples by applying selective chemical extractions followed by ICP-MS analysis. The second one is an individual particle analysis done by ESEM-EDS, micro-PIXE and micro-Raman. This paper presents the results from initial studies aiming to demonstrate the relevance of our methodology. Primary information about the main physico-chemical species of lead found in ambient air particulate matter, collected in the vicinity of a lead and zinc smelter, are given.
