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。

In order to study the pollution of non-methane hydrocarbons in the atmosphere around the airport, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. collected 2 sampling points near the take-off and landing point of an airport and the farmland area of the control point for 5 consecutive days from April 21, 2011. determination of NMHCs in the atmosphere. The results showed that the content of NMHCs in the taxiing point (3.22mg/m3), the landing point (2.92mg/m3) and the farmland area (2.91mg/m3), all exceeded the Israeli standard (2.0mg/m3). Total non-methane hydrocarbons reach a minimum at 16:00 pm during the day. The take-off and landing of aircraft has a certain impact on the emission of NMHCs in the surrounding atmosphere. The farmland emissions at the control point may be an important source of local NMHCs emissions. Among the three sampling points, the hydrocarbons emitted 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 means of statistical regression.
