中文摘要:
      为加强公路路面灰尘及其径流污染研究与防治工作,首先通过综合分析国内外文献,汇总了当前路面灰尘重金属污染研究在重金属污染来源、污染特征、粒径分布特征及路面径流重金属污染特征、排放规律等方面取得的成果。然后,指出由于公路与城市道路之间的差别,导致二者路面灰尘重金属污染特征存在显著的差异。最后,针对不同等级公路路面灰尘及重金属污染状况,从污染特征、迁移转化机制与规律、重金属的源解析及风险评价三个方面进行了研究展望,以期为后续研究工作提供借鉴。
英文摘要:
      In order to research and prevent the heavy metal pollution of road deposited sediments (RDS) and its runoff, firstly by comprehensively analyzing the domestic and foreign literatures, the current research achievements of heavy metal pollution of RDS were summarized, in the aspects of heavy metal sources, heavy metal pollution characteristics, particle size distribution characteristics of RDS, characteristics and emission regularity of heavy metal in runoff. Then, the significant differences on the heavy metal pollution characteristics of RDS between highway and urban road caused by their different conditions were pointed out. Finally, the research prospects of heavy metal pollution of RDS for different grade highways were proposed from three aspects: pollution characteristics, migration and transformation mechanism and law, source analysis and risk assessment of heavy metal, so as to provide references for the follow-up studies.
