摘要
通过对北京经济技术开发区开展的大气环境和污染源监测,研究区域环境空气中颗粒物污染特征。根据不同功能区PM10(可吸入颗粒物)浓度空间分布特征和累积效应,表明区内道路扬尘和施工扬尘是该区域大气颗粒物的主要污染源。根据对道路边界的降尘监测,表明施工工地对道路扬尘的影响非常大。对于处于建设发展期的区域,加强施工扬尘和道路扬尘控制是保证空气质量的重要措施。
This paper studied on characteristics of PM10 pollution of regional environment by monitoring the atmosphere environment and pollution sources in BDA. We found BDA＇s PMlo pollution mainly attributes to fugitive dust from roads and construction sites of BDA according to the spatial distribution characteristics and accumulation effect of PM10 concentration. The monitoring results of three roads＇ dust fall in BDA indicated construction sites can increase city road dust emission. To assure the atmosphere quality in developing regions, it is an important measure to strengthen the control of fugitive dust from construction sites and city roads.
