为了研究机场周边大气中非甲烷烃的污染情况,浩瀚色谱（山东）应用技术开发有限公司于2011年4月21日起连续5天对某机场起降点附近2个采样点以及对照点农田区的大气中NMHCs进行测定。结果表明,NMHCs的含量为飞机开始滑行点(3.22mg/m3)降落点(2.92mg/m3)农田区(2.91mg/m3),均超出以色列的标准(2.0mg/m3)。非甲烷总烃在一天中下午16点达到小值。飞机的起降对周边大气NMHCs排放有一定的影响。而对照点农田排放可能是当地NMHCs排放的重要来源。3个采样点中,排放的碳氢化合物以非甲烷烃为主,占总烃的63.4%。NMHCs和总烃的线性关系良好,用统计回归的方法得到了研究区总烃和非甲烷烃的换算公式。

Name: Total Hydrocarbon Packed Column

Stationary phase: silanized glass microspheres

Granularity: 60-80 mesh

Specification: 1m*1/8

Model: HH-BLQ



In order to study the pollution of non-methane hydrocarbons in the atmosphere around the airport, Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. conducted 5 consecutive days on April 21, 2011 on two sampling points near an airport’s take-off and landing point and a reference point in the farmland area. Determination of NMHCs in the atmosphere. The results show that the content of NMHCs is the starting point (3.22mg/m3) of the aircraft and the landing point (2.92mg/m3) of the farmland area (2.91mg/m3), all exceeding the Israeli standard (2.0mg/m3). Non-methane total hydrocarbons reach their minimum value at 16:00 in the afternoon. The take-off and landing of aircraft has a certain impact on the surrounding atmospheric NMHCs emissions. The farmland emissions from the control sites may be an important source of local NMHCs emissions. Among the three sampling points, the emitted hydrocarbons are mainly non-methane hydrocarbons, accounting for 63.4% of the total hydrocarbons. The linear relationship between NMHCs and total hydrocarbons is good, and the conversion formula of total hydrocarbons and non-methane hydrocarbons in the study area is obtained by statistical regression method.
