This paper presents results of measuring episodes of extremely high ozone concentrations in urban area of the town of Bor in Serbia. The measured ozone concentration of 3000 mu gm(-3) in two episodes, which lasted 3-5 days in November 2010, has not been recorded in the literature in this field. Sensitivity of generated ozone to the NOx was determined, since the concentrations of NOx in the same period were also high. In the morning when working hours start, episodes of increased NOx concentrations appear after several hours, leading to episodes of increased ozone concentrations reaching up to twenty times more than the threshold value, defined as harmful to vegetation and human health.
