  • 摘要: 以重庆市永川区小城镇为例进行调查研究,结果表明,工业园区道路街尘和城乡结合部道路街尘以200 μm以上粒径段为主(65%-72%),而商业区和双竹镇街道以200 μm以下粒径段为主(60%-72%);有机质和总磷、总氮、锌、铅、镉的最高浓度出现在商业区街尘(分别为103.04 mg·g-1和785.48、1672.04、439.72、133.30、8.44 mg·kg-1),工业园区道路街尘含有最高的铜、镍浓度(分别为241.52和92.30 mg·kg-1).小城镇街道街尘污染评价结果表明,商业区街尘和工业园区道路街尘污染风险较高,其中商业区街尘中的镍处于重度污染等级,工业园区道路街尘中的镉达到极度污染最高等级,同时,小城镇街尘控制对策分析指出,在"源"-"传输过程"-"汇"三个环节分别采取措施控制小城镇街尘污染是可行的.
    Abstract: To examine the pollution status in street dust in small towns, the distribution of pollutants in small towns of Yongchuan District, Chongqing City, was investigated. The results showed that particulate matter above PM 200 μm is the predominant fraction in street dust from Industrial Area and Xuefu Road (e.g., 65% and 72%, respectively), while below 200 μm is the main proportion for Commercial Area and Shuangzhu Street (e.g., 72% and 60%, respectively). The highest concentrations of organic matter, total phosphorus, total nitrogen, Zn, Pb and Cd were found in street dust in Commercial Area (e.g., 103.04 mg·g-1,785.48,1672.04,439.72,133.30,8.44 mg·kg-1, respectively), and the highest contamination levels of Cu, Ni appeared in roads located in Industrial Area (e.g., 241.52 mg·kg-1 and 92.30 mg·kg-1, respectively). The result of pollutants assessment with geoaccumulation index indicated that street dust in Commercial Area and road in Industrial Area had higher contamination risk, especially Ni in Commercial Area dust and Cd in road dust in Industrial Area, which are at the heavily contaminated level and extremely contaminated degree, respectively. Highlight was given to the control of street dust contamination in small towns, and three parts were proposed to be essential for more efficient management of street dust.
