Resumo
This study deals with the seasonal distribution of Al, Ca, Cu, Fe, K, Mg, Na, Pb and Zn and
water soluble ions (Cl-, PO4
3-, NO3
-, SO4
2-, HCOO-, CH3COO-, oxalate, succinate, Na+, NH4
+,
K+, Mg2+ and Ca2+) found in PM10 samples (particulate matter less than 10 mm in diameter)
São Paulo City, Brazil, (April 2003-May 2004). Higher atmospheric levels were found for SO4
2-,
NO3
-, Cl- and PO4
3- while the main organic anions were oxalate and formate. Atmospheric levels
for elements were: Fe > Al > Ca > K > Na > Mg > Zn > Cu > Pb. Some sources were predominant
for some species: (i) fuel burning and/or biomass burning (NO3
-, HCOO-, C2O4
2-, K+, Mg2+, Ca2+,
Fe, Pb, Zn, Al, Ca, K and Mg), (ii) gas-to-particle conversion (SO4
2- and NH4
+) and (iii) sea salt
spray (Cl-, Na+ and Na).
