Oznaczono zawartość niektórych metali ciężkich i wielopierścieniowych węglowodorów aromatycznych (WWA) w glebach pobranych z tras komunikacyjnych w Krakowie w m-cu czerwcu 1991 r. Zaobserwowano wzrost zawartości oznaczanych WW A w punktach o zwiększonym nasileniu ruchu kołowego. Dla metali stwierdzono znaczne przekroczenia najczęstszych ogólnych zawartości w warunkach naturalnych.

The concentration of heavy metals and polycyclic aromatic hydrocarbons (PAH) were determined in the soils obtained from various traffic roads in Cracow including sorroundings of steel works. The method of atom absorption spectromery was using to determination of Ca, Mg, Pb, Fe, Zn, Cd, Cu. PAH (fluoranthene, pyrene, benz(a)anthracene + chryzene, benz(a)pyrene, benz(ghi)perylene, fenanthrene and perylene) were determined by gas chromatography. The higest concentration of heavy metals was found in zone of steel works. A steep fall concentration of Fe was observed in the soils with increasing distance from the works. It seems that the variety in concentration of metals don't depend only on vehicular traffic. The highest mean PAH concentration exceeding 800 µg/kg of dried soils was found in soil samples taken from roads where the traffic is the highest.
