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.

There has been investigated the soils buried under the body of the shaft of the early iron age and modern (background).There has also been carried out comparing them to assess the environmental condition of the landscape with in which the profiles of soil are situated. It has been defined that soil formation processes that underpinned the modern profiles and buried (ancient) soil, are characterized by a combination of processes of capable of the accumulation of substances, radionuclides and heavy metals. It has been determined that the amount of heavy metals lies within background values. The obtained data testify the fact that in the modern (background) soil the heavy metals are being accumulated in arable horizon. It has been fixed that in the modern soil the concentration of heavy metals in profile is a higher than in buried one. This shows the change of conditions and factors that affect geochemistry of the landscape for a long time of their formation
