ArcGIS analysis was applied to study the content level and the spatial distribution characteristics of As and Pb in street dust of Huludao city. Geoaccumulation Indexes and Potential Ecological Risk Index technique were applied to assess the ecological risk of As and Ph. The average contents of As and Pb were 33.10 mg x kg(-1) and 533.2 mg x kg(-1), which was 4 and 25 times as high as the background value respectively. The trends for Pb and As were similar with higher concentrations near Huludao Zinc Plant (HZP). The ecological risk of As and Pb contamination in street dust were serious, and the accumulation of Pb in street dust was higher than the As.
运用ArcGIS分析研究葫芦岛市街道灰尘中砷和铅的含量水平及空间分布特征。采用地累积指数和潜在生态风险指数技术评估砷和铅的生态风险。砷和铅的平均含量分别为33.10毫克/千克和533.2毫克/千克，分别是背景值的4倍和25倍。铅和砷的含量趋势相似，在葫芦岛锌厂（HZP）附近浓度较高。街道灰尘中砷和铅污染的生态风险严重，且街道灰尘中铅的累积高于砷。
