南京市建筑扬尘排放清单研究

统计分析了2010年南京市各行政区建筑场地面积和工期，结合扬尘排放因子，建立了南京市建筑扬尘排放清单。研究表明，2010年南京市建筑扬尘TSP、PM10和PM2．5的排放量分别达2．53万t、1．40万t和0．95万t，占工业烟（粉）尘排放量的23％、13％和8．6％。郊区县建筑扬尘排放量较大，约占全市 TSP、PM10、PM2．5排放总量的72％；主城区排放强度较高。对不同建筑工程类型扬尘排放量估算表明，城市建设工程和市政工程是建筑扬尘的主要来源，城市建设工程中又以住宅类建设工程为主。对不同研究获得的建筑扬尘结果比较，发现扬尘排放因子选择和污染源活动水平统计是影响建筑扬尘结果的关键因素。

Emission Inventory of Construction Fugitive Dust in Nanjing

Based on the analysis construction area and construction period in Nanjing in 2010,the emission inventory of construction fugitive dust was established combining with the emission factors.The results showed that the emissions of construction fugitive dust were 25.3 kt,14.0 kt and 9.5 kt respectively for TSP,PM10 and PM2.5 ,which accounted for 23%,13% and 8.6% of the industrial smoke dust.The emissions of construction fu-gitive dust in suburban counties were large,which accounted for 72% of the whole city.The emission intensity of construction fugitive dust was high in main urban area.The estimation of different type of construction dust emis-sions showed that city construction project （mainly residential construction project）and municipal project were the main source of construction fugitive dust.The results of construction fugitive dust from different studies were compared and it was found that emission factor selection and pollution activity collection were the key factors that influence the inventory results.
