title: [Levels and profiles of polycyclic aromatic hydrocarbons in Zenica in relation to the seasons].
abstract: Twelve polycyclic aromatic hydrocarbons were measured in samples of airborne particles collected in the town of Zenica in the Republic of Bosnia and Herzegovina every third or fourth day throughout the year. The concentrations were especially high in winter when in addition to permanent industrial emissions those from individual heating systems were also present and when owing to climatic and orographical circumstances temperature inversions occurred more frequently. The profiles of polycyclic aromatic hydrocarbons i.e. their ratios to benzo-a-pyrene did not demonstrate great seasonal variations with the exception of fluoranthene and pyrene. The mean annual concentrations (winter to summer concentration ratios) were higher than in the areas where there was no permanent source of emissions.
