中文摘要:道路扬尘是城市颗粒物的重要来源, 导致霾污染加重; 影响城市景观、增加市容清洁成本等; 直接或间接 引起呼吸系统疾病而影响市民的身心健康。研究分析了上海典型道路扬尘的化学成分, 并使用化学质量平衡模型 EPA-CMB8.2 进行了源解析工作。研究结果表明, 典型道路扬尘的污染源按分担率排序依次为土壤风沙尘 (36.7%)、 搅拌站粉尘 (25.0%)、渣土码头尘 (14.7%)、建筑工地尘 (11.0%)、机动车尾气尘 (0.9%)。其中, 土壤风沙尘、搅拌站 粉尘、渣土码头尘和建筑工地尘是典型道路扬尘的主要来源, 分担率合计大于 85%。总结研究过程中获得的经验, 提出了针对道路扬尘、施工扬尘和堆场扬尘的污染防治建议。

Source Analysis in Road Dust of Typical Roads in Shanghai
Abstract:Road dust is the important source to urban particulate matters which worsen haze pollution, influence the urban landscape, and increase the cost of urban appearance cleaning. It can bring about serious respiratory diseases directly or indirectly, which might damage on the physical and mental health of the citizens. The chemical composition of typical road dust was analyzed, and the source analysis was carried out using the chemical mass balance model EPA-CMB8.2. The results show that the pollution sources of typical road dust are sorted according to the contribution rate: soil dust (36.7%), mixing plant dust (25.0%), muck wharf dust (14.7%), construction site dust (11.0%) and motor vehicle exhaust dust (0.9%). Among them, soil dust, mixing station dust, muck wharf dust and construction site dust are the main sources of typical road dust, and the total contribution rate is greater than 85%. Based on the experience gained in the research, we put forward suggestions for the prevention and control of road dust, construction dust and yard dust pollution.
