【 摘 要 】

The intense urbanization process has conditioned a significant number of ecological problems connected with a rapid deterioration of the quality of urban environment. All that calls for indication and an unbiased assessment of its current state. The distribution of heavy metals in the town's soils was in the following descending order: lead > zinc > nickel > copper > cadmium > mercury > arsenic. Largest values of contaminating substances were determined in the territories adjacent to motorways. The maximum value of oil products content in soils of the researched areas was determined on a motorway section and was 280.9 mg/kg which corresponds to an "acceptable" level. Researched soils had no express acute toxicity which is indicative of acceptable ecotoxicological state of the town's soils.
