The concentrations of smoke, polycyclic aromatic hydrocarbons (PAHs), and some gaseous air pollutants have been measured in two London Transport diesel bus garages and compared with observations made in the same garages over 20 years earlier. The main feature of the results was a large reduction in the background concentrations of smoke and polycyclic aromatic hydrocarbons from sources such as coal fires, attributable to the implementation of the Clean Air Act. Contributions from the buses to the benzo(a) pyrene content of the air inside the garages were of the same magnitude as before, being small in relation to former coal smoke contributions.
在两个伦敦交通柴油巴士车库中测量了烟雾、多环芳烃（PAHs）和一些气态空气污染物的浓度，并与20多年前在同一车库进行的观测结果进行了比较。结果的主要特点是，由于《清洁空气法》的实施，来自煤炭燃烧等源的烟雾和多环芳烃背景浓度大幅降低。巴士对车库内空气中苯并[a]芘含量的贡献与以前相同，相对于以前煤炭烟雾的贡献较小。
