This study was designed to assess the impact of the inorganic composition of particulate matter on 33 adult asthmatics respiratory functions in São Paulo city, Brazil. From May to July 2002, fine and coarse particulate matter fractions were collected and trace metals (Fe2+, Mn2+, Zn2+, Pb2+, Cu2+) and major ions (Na+, Mg2+, K+, Ca2+, NH4 +, Cl-, NO3-, SO42-) composition was determined in each aqueous-extract fraction by Atomic Absorption Spectrometry with Graphite Furnace (AAS-GF) and Ion Chromatography, …
