分析柱：2m*1/8
预柱：0.2m*1/8

为研究工业园区环境空气中苯系物的污染状况和季节变化特征,浩瀚色谱（山东）应用技术开发有限公司选取石化工业区、化工园区和经济开发区共14个监测点位于春、夏、秋三季分别采集大气样品,并利用三级冷阱预浓缩-GC-MS方法进行分析。结果表明:苯、甲苯、乙苯等典型苯系物检出率均高于90%;污染程度与不同季节的气候变化密切关联,春季污染较为严重,秋季次之,夏季污染较轻;苯系物浓度大测定值远远低于我国《工业企业设计卫生标准》(TJ36-79)中规定的居住区大气中有害物质的高容许浓度。

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).
