[PAHs pollution in air of coke plant and health risk assessment].
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.
