| 摘 要： | PM2．5现在是中国大气中的主要污染物，而NH3作为前驱物，越来越受到大家的重视，在以往NH3监测中，往往采取手工采样和化学分析的方法进行监测，难以长时间不间断获得NH3的实时浓度。而选取利用Thermo公司的17i仪器则可以做到实时监测NH3的变化，继而分别对北京市区、农村和交通站周边的NH3进行了连续监测，发现市区浓度高于郊区，夏天浓度高于冬天，交通源对NH3排放有较大影响。

| Abstract: | PM2.5 is nowthe main pollutant in the air, and NH3 as its precursor,has received more and more attention.NH3 monitoringin the past, oftenadoptsmanualsamplingandchemical analysismethods.It is difficultto obtainlong continuousreal -time concentrationof NH3.By selecting Thermo 17i instrument,real-time monitoringof NH3 change can be achieved.17i of Thermo company is used to monitor the NH3 of urban and rural areas of Beijing City and areas around the traffic stations.It is found that the concentration of urban areas is higher than that of the suburbs , and the concentration of summer is higher than that of winter , and the traffic sources have a significant influence on NH3 emissions. |
