摘要：

Atmospheric aerosol samples were collected downtown. The concentration of the anions of Cl, Br, NO//3 and SO//4, and the components Ca, Cu, Fe, Mg, Pb, Sr, Zn and total C was determined. A comparison of the relative composition of size fractions containing nucleation and accumulation mode particles showed that the components derived from traffic emissions (Pb, Br and C) were enriched in the nucleation mode size fraction. On the other hand, each of the components Cl, SO//4, Ca, Cu, Fe, Mg and Sr has a similar relative concentration in the nucleation mode and in the accumulation mode size fraction. For all samples collected on days with prevailing westerly winds, a strong negative correlation between wind speed and sulfate particle size as well as sulfate concentration was observed.
