Purpose. The aim of the paper is determine of atmospheric air quality withim the main Bus Stations in Kharkiv. Methods. The following methods were used: filed, laboratory and statistical ones. Results. The results of the researches was found that the content of dust, carbon monoxide and nitrogen dioxide in the atmospheric air of the city of Kharkiv around Bus stations №1 " Avtovokzal", № 3 " Kinnyj Rynok", № 6 "Zavodska", and Kholodna Gora Terminal higher than MACs. The highest concentrations of pollutants were identified around Bus stations Nr 6 “Zavodska” and Kholodna Gora Terminal. It have shown a tendency to increase in atmospheric air concentrations of gasoline, carbon monoxide, nitrogen dioxide. The temporal tendency to increase in atmospheric air concentrations of gasoline, carbon monoxide, nitrogen dioxide was revealed. Conclusions. The detected excess of the MPC of harmful substances in the atmospheric air of the city of Kharkiv in the districts of the bus stations indicates a difficult situation with the quality of atmospheric air in the cities of intensive traffic, especially in the respiration zone of children. Recommendations aimed at improvement of air quality was proposed.

Reasons of environment pollution by waste motor oils (WMO) and aspects of environmental safety of WMO are considered. The volume of WMO generation by vehicles is calculated for Kharkiv Oblast (year 2013). Economic losses for environment pollution caused by illegal WMO utilization are calculated. Based on experimental researches, ash and sulphur contents were measured. Comparison of obtained data with M40 masut parameters has shown that WMO ash and sulphur contents are higher than the same parameters for masut. In ash from M100 masut ten heavy metals were identified; concentration of all metals (except Cu) is WMO ash was higher than their concentration in M100 masut ash. It is shown that WMO can be utilized through burning only in case of implementation of set of protective measures.
