多环芳烃(Polycyclic Aromatic Hy-drocarbon,简称PAH)产生于燃料(煤炭、汽油、木柴等)不完全的燃烧过程中,在利用这些燃料作原料进行热加工处理时也能形成。PAH包括的化合物甚多,有一部份已证明对动物具有致癌作用,其中3,4-苯并芘(3,4-Benzopyrene,简称BaP)发现得很早,致癌作用很强,研究得也很广泛。胜治进一曾报告,每克燃料燃烧时所产生的BaP量(微克)如下:煤67～136,木材62～125,原油40～68,汽油12～
Polycyclic Aromatic Hy-drocarbon (PAH) is produced during incomplete combustion of fuel (coal, gasoline, firewood, etc.) and can also be formed by thermal processing using these fuels as raw materials. PAH contains a large number of compounds, some of which have been shown to have carcinogenic effects in animals. 3,4-Benzopyrene (BaP) is found very early and has a strong carcinogenic effect. widely. Masayuki Morimichi once reported that the amount of BaP (μg) produced per gram of fuel when burned is as follows: coal 67 to 136, wood 62 to 125, crude oil 40 to 68, gasoline 12 to 40,
