工業(yè)區(qū)環(huán)境空氣苯系物污染在線測定 詳細信息：

分析柱：2m*1/8
預(yù)柱：0.2m*1/8

為研究工業(yè)園區(qū)環(huán)境空氣中苯系物的污染狀況和季節(jié)變化特征,浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司選取石化工業(yè)區(qū)、化工園區(qū)和經(jīng)濟開發(fā)區(qū)共14個監(jiān)測點位于春、夏、秋三季分別采集大氣樣品,并利用三級冷阱預(yù)濃縮-GC-MS方法進行分析。結(jié)果表明:苯、甲苯、乙苯等典型苯系物檢出率均高于90%;污染程度與不同季節(jié)的氣候變化密切關(guān)聯(lián),春季污染較為嚴重,秋季次之,夏季污染較輕;苯系物濃度大測定值遠遠低于我國《工業(yè)企業(yè)設(shè)計衛(wèi)生標準》(TJ36-79)中規(guī)定的居住區(qū)大氣中有害物質(zhì)的高容許濃度。

On-line measurement of benzene series pollution in ambient air of industrial zone
On-line determination of benzene series pollution in the ambient air of industrial areas. Details:

Analysis column: 2m*1/8
Pre-column: 0.2m*1/8

In order to study the pollution status and seasonal change characteristics of benzene series in the ambient air of the industrial park, Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. selected 14 monitoring points in the petrochemical industrial zone, chemical park and economic development zone in spring, summer and autumn. Atmospheric samples were collected in the three seasons, and analyzed by the three-stage cold trap pre-concentration-GC-MS method. The results show that the detection rate of typical benzene series such as benzene, toluene, and ethylbenzene are all higher than 90%; the pollution degree is closely related to the climate change in different seasons, the pollution is more serious in spring, followed by autumn, and the pollution is lighter in summer; benzene series The maximum measured concentration of substances is far lower than the maximum allowable concentration of harmful substances in the atmosphere of residential areas specified in China's "Design Sanitary Standards for Industrial Enterprises" (TJ36-79).
