摘　　要：建筑施工活动引起的扬尘是我国城市空气颗粒物污染的重要来源,选择天津市一处典型的建筑施工工地作为研究对象,分施工阶段对环境空气PM10、尘源样品和降尘等进行了系统监测实验,得到了建筑扬尘的成分谱(元素、离子和碳组分)和尘源样品的粒径分布.结果表明,建筑施工扬尘的污染特点和化学组成特征与具体施工阶段、施工操作和建筑材料等密切相关.通过采集工地周边的降尘,发现利用降尘可以作为工地扬尘的监控指标.The fugitive dust caused by construction activities is an important source of urban particulate matter pollution, but no detailed study has been done on this topic in China. In this study, a typical building construction site located in the Tianjin urban area was selected and the whole construction process from ground excavation to general construction was studied. The ambient PM10, source samples and dustfall were collected on site. The chemical profiles （including elements, ions and carbon） of fugitive construction dust and the size distributions of source samples were obtained. The results show that the emissions and chemical compositions of fugitive construction dust are closely related to construction activities and construction materials. And the dustfall can be used as a control indicator of fugitive construction dust.
