Environmental Impact by Heavy-Metal Dispersion from the Fine Sediments of the Shuangqiao River, Xiaoqinling Gold Area, China

Abstract:

Abstract. the sediments is the second pollution source to the water quality of river in mining area, in order to assess the pollution extent of the Shuangqiao River by anthropogenic activity, and establish the geochemical background values and the possible geochemical anomaly range, The authors use Lognormal distribution plots to study the Mercury, Chromium, Cadmium, Lead, Copper, Arsenic, Zinc and Iron dispersion in the fine sediments of the Shuangqiao River. The Lognormal distribution plots are applied to discriminate the geochemical background levels of eight heavy metals from the geochemical anomalies. The result shows that Mercury, Lead are the most heavily pollution which is related to anthropogenic activities, and the concluded geochemical background value is more reasonable than before.
