| Abstract: | Nineteen trace metals in PM-{10} were measured by X-ray fluorescence spectroscopy (XRF) at three sites in Chongqing. The special and seasonal variations of trace metals in PM-{10} samples collected in the downtown were different from those in the background area of Jinyunshan. The source identification indicated that particulate materials were contributed mainly by two sources. |
