摘要
为研究上海市建筑施工扬尘排放特征,选取浦东新区典型主体建设阶段工地为研究对象,对其周边水平和垂直点位开展扬尘在线监测,同步观测风速风向,并依据暴露高度浓度剖面法计算总悬浮颗粒物(TSP)排放量和排放因子。结果显示:工地水平方向上TSP最高日均值和最大日质量浓度分别为0.137、0.186mg/m^3,风速是影响施工场地周边TSP浓度的重要因素。TSP小时变化呈现双峰型分布,TSP垂直分布总体上随高度增加而降低。此外,监测期间该工地TSP排放量为62.32kg,排放因子为0.003 6g/(m^2·h)。
To study the emission characterizations of construction fugitive dust,one typical construction site in Pudong New Area of Shanghai was selected as sampling site in this study.The total suspended particulates(TSP)online monitoring was conducted in horizontal and vertical directions surrounding the construction site,and wind speed and wind direction were monitored simultaneously.Then the total emission amount and emission factor of TSP were calculated according to exposure profiling method.Results showed that the maximum average daily concentration and highest diurnal concentration in the horizontal direction were0.137and0.186mg/m^3,respectively,and wind speed was an important factor affecting TSP concentration.TSP displayed a bimodal distribution for diurnal variation.The vertical distribution of TSP generally decreased with height.Additionally,the total emission amount and emission factor of TSP were62.32kg and0.0036g/(m^2·h),respectively.
