2m*1/8甲烷柱 詳細(xì)信息：

名稱：甲烷柱
規(guī)格：2m*1/8
型號(hào)：GDX-502

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。

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.
