為了研究機場周邊大氣中非甲烷烴的污染情況,浩瀚色譜（山東）應用技術開發有限公司于2011年4月21日起連續5天對某機場起降點附近2個采樣點以及對照點農田區的大氣中NMHCs進行測定。結果表明,NMHCs的含量為飛機開始滑行點(3.22mg/m3)降落點(2.92mg/m3)農田區(2.91mg/m3),均超出以色列的標準(2.0mg/m3)。非甲烷總烴在一天中下午16點達到小值。飛機的起降對周邊大氣NMHCs排放有一定的影響。而對照點農田排放可能是當地NMHCs排放的重要來源。3個采樣點中,排放的碳氫化合物以非甲烷烴為主,占總烴的63.4%。NMHCs和總烴的線性關系良好,用統計回歸的方法得到了研究區總烴和非甲烷烴的換算公式。

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.
