| 摘要 | Atmospheric deposition, soil, plant, ore, and coal cinder samples were collected and analyzed to determine heavy metal concentrations in a typical peri-urban industrial area of Baoji. The lead isotope ratio method was employed to trace the source and dispersion of atmospheric heavy metal contamination. Results showed that concentrations of lead, zinc, cadmium, and copper in atmospheric deposition significantly exceed soil background levels and Chinese soil environmental quality standards. The most polluted sites were located in the downwind direction of the smelter, which confirmed this site to be the major pollution source for this area. The other source of heavy metals in this area is a power plant. The investigation into lead isotopes revealed compositions in atmospheric deposition samples were similar to those in ores and coal cinders identifying smelting as the predominant pollution source of lead with the power plant having a minimal effect. Similar isotopic compositions were also found in plants, indicating that the major source of lead in plants was derived from atmospheric deposition, although some evidence was found to suggest uptake from the soil to the roots as an additional contaminant pathway. |
