為了研究機(jī)場周邊大氣中非甲烷烴的污染情況,浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司于2011年4月21日起連續(xù)5天對某機(jī)場起降點(diǎn)附近2個(gè)采樣點(diǎn)以及對照點(diǎn)農(nóng)田區(qū)的大氣中NMHCs進(jìn)行測定。結(jié)果表明,NMHCs的含量為飛機(jī)開始滑行點(diǎn)(3.22mg/m3)降落點(diǎn)(2.92mg/m3)農(nóng)田區(qū)(2.91mg/m3),均超出以色列的標(biāo)準(zhǔn)(2.0mg/m3)。非甲烷總烴在一天中下午16點(diǎn)達(dá)到小值。飛機(jī)的起降對周邊大氣NMHCs排放有一定的影響。而對照點(diǎn)農(nóng)田排放可能是當(dāng)?shù)豊MHCs排放的重要來源。3個(gè)采樣點(diǎn)中,排放的碳?xì)浠衔镆苑羌淄闊N為主,占總烴的63.4%。NMHCs和總烴的線性關(guān)系良好,用統(tǒng)計(jì)回歸的方法得到了研究區(qū)總烴和非甲烷烴的換算公式。

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.
