| Lead Isotopes as Tracers in the Qixiashang Lead-Zinc Mining Area, Nanjing |
| The Qixiashan lead-zinc mine in Nanjing has been exploited for more than 50 years, and environmental pollution has become increasingly serious. In order to investigate the source and dispersion of the pollution, the authors collected water, soil, plants, atmospheric deposition, vehicle exhaust dust, ore, human blood and biological samples and analyzed heavy metals concentrations and lead isotopes with ICP-MS. The results show that the concentrations of heavy metals in soil, plants, and atmospheric deposition are very high, and the nearer to the mining area, the heavier the pollution. In addition, Pb, As, Cd, Cu and Zn show obvious correlation. Analyses of lead isotopes show that the lead isotope compositions in atmospheric deposition, plants, and part of soils and biological samples around the mining area are similar to those in ores, indicating that the pollution source has been derived form the mine. Furthermore, atmospheric deposition and plants have high lead concentrations and similar lead isotope compositions, suggesting that lead in atmospheric deposition contributes substantially to lead transfer. |
