在焦炉顶端采集颗粒物样品,用气相色谱-质谱联用技术测定了其中13种多环芳烃的含量.通过与燃煤烟尘和交通隧道中BaP含量的比较,说明焦化作业是造成多环芳烃污染的重要污染源之一.将分析结果进行归一化处理后,确定了焦化厂多环芳烃成分谱,这一成分谱在轮廓特征和特征比值方面都表现出与燃煤型污染的相似性,而与交通型污染差别较大.

Particulate samples were collected on the top of coke oven, in which the contents of 13 kinds of PAHs were determined by the use of GC-MS technique. Through comparing with BaP content in coal smoke and traffic tunnels, it indicates that coking work is one of important sources of PAHs pollution. The source profile was determined by averaging the ratios of individual PAH concentration to the total concentration of all PAHs measured, which in the aspects of both outline character and characteristic ratios shows that the pollution from coking is similar with that from coal combustion and rather different from that of traffic tunnel type.
