摘要
研究了上海不同功能区(工业区、商业区、学院区)大气中NMVOC的组成特点。各功能区大气中的有机物先用高分子聚合物Tenax-TA在常温下富集,再经GC-MS联用仪进行分析。结果表明:上海市大气中的NMVOC有282种;工业区和商业区的NMVOC主要来自人为源,而学院区的NMVOC则来自天然源和生活活动。
Hydrocarbons in ambient air were concentrated at normal temperature by Tenax-TA in the industrial area, commercial area and college area respectively. The samples were determined by GC-MS. It showed that there were as many as 282 NMVOCs in ambient air of Shanghai. By analyzing the characteristics of NMVOC in different functional zones, it found that NMVOC in the industrial zone and commercial zone were produced artificially, where as in the college zone were produced both naturally and artificially.
