Mercury contaminations from mercury and stibium mining to stream water, arable soil and sediments in Xunyang, Shaanxi Province, China

摘要：

The concentrations of mercury in stream water, arable soil and sediments collected from mercury and stibium mining area in Xunyang, Shaanxi, China were measured by cold vapor atomic fluorescence spectrometry with EPA 1631. Total Hg concentrations were highly elevated ranging from 1.28 to 225mg·kg<1> in the samples of soil and 188 to 1787mg·kg<-1> in the samples of sediment, respectively. The concentration of total Hg in stream waters of Zhutong River varied from 0.46 to 25.6μg·L<1> in the wet season. The results show a regional dispersion of mercury contamination.
