| 摘 要： | 2010年9月和2011年3月在杭州市区布设193个NH3监测点位，采用意大利柯瑞Ring被动采样设备同步采集大气NH3样品.利用实验室离子色谱分析仪对获得的样品进行分析，并通过ARCGIS插值法得到杭州市区大气中NH3的时空分布特征.结果表明，杭州市区NH3平均质量浓度为7μg/m3，未超过国家居住区NH3质量浓度最高限值200μg/m3；氨气质量浓度的时空分布特点呈现东部高西部低，9月高3月低；气象因素与氨的排放源强是影响大气NH3分布的主要因素.

| Abstract: | Ammonia samples were collected at 193 sites in Hangzhou in September 2010 and in March 2011 using Italy Kerry Ring passive sampling device. The concentrations of NH4+ were measured by ion chromatography. Temporal and spatial distributions of ammonia were calculated by ARCGIS interpolation. The results show that the average concentration of ammonia was 7 μg/m3 in Hangzhou, which did not exceed the health standards for the design of Chinese industrial enterprise of 200 μg/m3. Ammonia concentration was higher in the east part of the city than in the west and was higher in September than in March. Meteorological factors and source strength of ammonia are the main factors affecting atmospheric ammonia distribution. |
