- 摘要:
- 通过对西安市城区6个公园表层土壤和地表灰尘的取样调查，采用单项指数法、综合指数法、潜在生态风险指数法对其进行重金属污染评价，利用多元统计方法探讨了土壤和灰尘重金属间密切程度。结果显示：西安市公园土壤和灰尘中5种重金属元素Cu，Cd，Zn，Pb，Cr均值含量均高于陕西省土壤背景值。表层土壤和地表灰尘主要受到Pb，Cu，Cd的污染；土壤重金属污染多属中度—重度污染，灰尘重金属污染均属重度污染；公园土壤重金属元素潜在生态危害均属轻微生态风险，大明宫遗址公园、革命公园、曲江池遗址公园和莲湖公园灰尘重金属元素潜在生态危害属“强—很强”生态危害，其中大明宫遗址公园地表灰尘中重金属元素Cd潜在生态危害系数达到978.33，属极强潜在生态危害；土壤和灰尘间对应重金属元素Cu和Cr存在极显著相关性，Pb存在显著相关性。
- Abstract:
- The surface soils and dust of six parks in urban areas of Xi’an City were sampled and analyzed. Single contamination index method, comprehensive contamination index method and potential ecological risk index method were used to evaluate heavy metal contamination. Multivariate statistical analysis was used to explore the relationship between heavy metals of the soil and the dust. Results showed that concentrations of all five heavy metals surveyed including Cu, Cd, Zn, Pb and Cr were higher than the soil element background values of Shaanxi Province. Surface soil and dust were mainly polluted by Pb, Cu and Cd. Heavy metal contamination levels of soil and dust were mostly middle/heavy pollution and heavy pollution respectively, the potential ecological risk of heavy metal pollution of soils in the parks was slight, the potential ecologic risks of heavy metal pollution of dust in Daming Palace Ruins Park, Revolution Park, Qujiang Pool Park and Lianhu Park were at high-very high level, especially the risk of Cd pollution of surface dust in Daming Palace Ruins Park was much higher, up to 978.33. Very obvious and obvious relationship was observed between the corresponding heavy metals such as Cu, Cr and Pb in surface soils and dust.
