昆明市街道灰尘重金属污染及潜在生态风险评价OA北大核心CSTPCD
Heavy Metal Pollution and the Ecological Risk Assessment of Urban Street Dust in Kunming
利用X-Ray荧光光谱仪对昆明市街道灰尘的Cu、Zn、Ph、As、Cr和Ni等元素进行了分析,讨论了街道灰尘中重金属含量的水平和空间分布特征;采用潜在生态危害指数法对灰尘中重金属的潜在生态风险进行了评价.结果表明:昆明市街道灰尘中重金属Cu、Zn、Pb、As、Cr和Ni的平均含量分别为166.6、316.53、97.49、20.56、79.41和21.45 mg/kg,与全国土壤背景值相比有较大积累,其中cu、zn、Pb和As都达到相对富集类,污…查看全部>>
The concentrations of Cu, Zn, Pb, As, Cr and Ni in urban street dust collected from Kunming were analyzed by using X-Ray fluorescence spectrometry. Spatial technique was applied to study the content level and the spatial distribution characteristics of heavy metal pollution in street dust of Kunming. The ecological risks of heavy metals in street dust were assessed with the potential ecological risk index method. The results show that the average concentrati…查看全部>>
