摘要
本文利用弹性石英毛细管色谱柱的气相色谱——质谱联用技术,与文献资料对照,对公路沥青拌砂点工作呼吸带空气颗粒物中有机物进行分离和鉴定,在所鉴定的八十五种化合物中,多环芳烃及其衍生物六十九种,链烃十四种,邻苯二甲酸酯二种,并对污染物的危害性和相关作用作了简单的讨论。
With fused-silica capillary column GC / MS method and the help of reference data, 85 organic pollutants were identified in airborne particles of breath zone in the site of mixture asphalt and stone for road use. In the main components, PAH, azo-PAH, and alkyl substitucnts account for 69, alkane and alkene from oil tar 14, and phthalates 2. The hazard and relation between PAH and alkanes were discussed briefly.
