| 摘 要： | 使用Tenax管在常温下富集采样 ,研究了南京市交通干道大气环境中苯系物的污染状况和季节变化规律 ,监测过程历时 1年。同时在中山陵设点采样 ,以作背景研究。经过GC/MS联用仪分析测定 ,共检出 140多种挥发性有机物 ,其中含量较高的是苯系物。结合获得的大气中苯系物的比值以及采样点的周围环境 ,对苯系物进行源分析 ,表明苯系物主要来源于汽车尾气的排放 ,其污染程度与气候变化有关。

| Abstract: | Pollution degree and seasonal variable regularity of BTEX in atmosphere by truck road in Nanjing were studied by Tenax at normal temperature.A 12-month monitoring program was performed during 2001.Meanwhile,background samples were taken in Sun Yat sen's Mausoleum.More than 140 VOC s were confirmed by GC/MS.The results showed that benzene had higher concentrations.The BTEX ratios and sampling environment suggested that vehicular tail gas was the dominant BTEX source in this area.The concentrations of BTEX could de changed with climate. |
