Özet

Twenty six trace elements were determined by INAA in the aerosol samples collected at two stations in Ankara, Turkey. Industrially derived elements, Se, As, Sb, Zn and Au did not show seasonal dependence and they were not substantially enriched. Elements originating from coal combustion are highly enriched and have higher concentrations in the winter. Correlation factors indicate that motor vehicles, coal and oil combustion are the main sources of aerosols over the city.
