| 摘 要： | 采集并分析了焦化厂不同生产工段环境空气中12种PAHs的浓度.结果表明,在某焦化厂区,12种PAHs浓度之和为11.75～46.66 μg/m3,其中BaP为0.050～1.054 μg/m3;PAHs浓度大小依次为:出焦处＞焦炉顶＞大门口＞熄焦处,焦炉顶和出焦处空气中BaP浓度远高于煤烟和交通干线.用毒性相当因子矫正后的焦化厂区PAHs浓度为0.3875～1.714 μg/m3矫正后的厂区工人口PAHs暴露率为3.100～13.71 μg/m3.

| Abstract: | 12 PAHs in air of different production sector in coking plant were measured with the result showing that, the total PAHs concentrations ranged from 11.75 to 46.66 micrograms/m3, among which, BaP was 0.050-1.054 micrograms/m3 descending following the order: the outlet of coke oven, the top of coke oven, the gate, the point of flaming out coke. BaP pollution in air of the top and the outlet of coke oven were much heavier than in the soot and in air of arterial road. The toxic equivalency factors (TEF) adjusted concentrations of total PAHs were 0.3875-1.714 micrograms/m3, and in this way, workers' daily exposure to PAHs were 3.100-13.71 micrograms/m3. |
