Winter atmospheric measurements of gaseous lower carbonyl and carboxylic acids were carried out simultaneously (in 1999) at two distinct urban sites located in the city São Paulo, Brazil. The greater metropolitan area Paulo is largest industrialized region Latin America has a highly polluted atmosphere. It an unconventional mix vehicle types that variety gasoline blends, including oxygenated ones, are used. Mixing ratios formic acetic ranged, respectively, from 0.6 to 19.4 0.1 10.6 ppbv one...
This study deals with the seasonal distribution of Al, Ca, Cu, Fe, K, Mg, Na, Pb and Zn water soluble ions (Cl-, PO4(3-), NO3-, SO4(2-), HCOO-, CH3COO-, oxalate, succinate, Na+, NH4+, K+, Mg2+ Ca2+) found in PM10 samples (particulate matter less than 10 mm diameter) São Paulo City, Brazil, (April 2003-May 2004). Higher atmospheric levels were for Cl- PO4(3-) while main organic anions oxalate formate. Atmospheric elements were: Fe > Al Ca K Na Mg Cu Pb. Some sources predominant some species:...
