Abstract
The relative proportion of 8 polycyclic aromatic hydrocarbons (PAH) is suspended particles from several sampling stations with different levels of air pollution (cities and rural districts) was investigated. The PAH-profiles of most samples collected in 3 winters (1974/1975, 1975/1976, 1976/1977) and in 1 summer (1975) were very similar. The PAH-profiles differ distinctly from these of several exhausts, especially regarding automobiles, coke and oil stoves. It can be presumed, that the mixture of the emissions in the atmosphere leads to a rather uniform relative proportion of the 8 PAH in the emission as much as the difference in stability of the PAH.
