The contents of copper, nickel, cobalt, lead, cadmium, manganese and chromium in the soil samples collected from 22 crossroads in the Kayseri city center on Kayseri-Ankara motorway were determined by flame atomic absorption spectrometry after digestion with aqua regia. The ranges of the metal ions in the soil samples are 19.8 - 65.1 mug/g for copper, 20.8 - 95.4 mug/g for nickel, 9.8 - 20.8 mug/g for cobalt, 15.6 - 92.8 mug/g for lead, < 0.2 - 1.6 mug/g for cadmium, 149.3 - 475.8 mug/g for manganese and 4.7 - 38.2 mug/g for chromium. The levels of investigated ions were increased with the traffic level. Significant correlation data were found between investigated heavy metal concentrations of the soil samples and traffic volume.
