為研究工業園區環境空氣中苯系物的污染狀況和季節變化特征,浩瀚色譜（山東）應用技術開發有限公司選取石化工業區、化工園區和經濟開發區共14個監測點位于春、夏、秋三季分別采集大氣樣品,并利用三級冷阱預濃縮-GC-MS方法進行分析。結果表明: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的氣候變化密切關聯,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《工業企業設計衛生標準》(TJ36-79)中規定的居住區大氣中有害物質的高容許濃度。

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).
