| Research Abstract |
The aims of the present study were to improve of the ultra-trace hexavalent chromium (Cr(VI)) analysis method in the atmosphere, to assess the risk of Cr(VI) in the atmosphere and to investigate the major emission sources. From the measurement results of Cr(VI) in the atmosphere, that is the risk level requiring attention was suggested. Trend slightly higher concentration in winter and summer was observed. And hexavalent chromium concentration was higher in small particles. Need for further investigation in the vicinity of the main road has been suggested.
