Abstract
Determination of polynuclear aromatic hydrocarbons in air was carried out in two monitoring sites of ‘Program Teplice’ throughout the year 1993. The town of Teplice is located in an industrialized region of the Northern Bohemia, Prachatice, a small town in Southern Bohemia, was chosen as reference. Measurement for PAHs was done in air at both locations and in bulk deposition at Teplice. Analysis of PAHs was done in air by HPLC with fluorescence monitor and in bulk deposition by CGC‐MS. Difference in the mean PAHs levels in air is not significant; particularly when taking benzo(a)pyrene as an indicator compound. Higher concentrations of PAHs were observed during the winter heating period at both locations.
