Opis:
In the course of the study, the following tasks were solved: determining the level of oil products and their spatial distribution in surface waters and bottom sediments of the Tura River, studying the features of the accumulation of oil products in bottom sediments in different sections of the Tura River, as well as the effect of storm and melt water contaminated with oil products within the coastal boundaries on the general background of pollution, calculated by the approximation method the distance at which the maximum permissible concentration for the Tura River would be reached, gave recommendations on the preservation of the object under study. The research was carried out in the laboratory of the Tyumen Industrial University. The analysis of samples for the content of oil products was carried out by the fluorometric method on a fluid analyzer “Fluorat-02–2M”. The results of the study indicate the need to monitor surface waters and toughly respond to insufficient compliance with the standards for the protection of surface waters and bottom sediments within the city of Tyumen.

Opis:
The research on the physical and chemical properties of landfill leachates and migration of its hazardous components into hydrosphere and biosphere is a current problem in the global context. The object of the research is landscape-changing factors of the Lviv municipal landfill (Ukraine). It was defined that the largest part of oil products accumulates in the leachates at the south-western side of the landfill (23.6 mg/dm3) and it is 2.36 times higher than the value of the maximum permissible concentration (MPC) (10 mg/dm3); the most saline leachates with chlorides and sulfites are those accumulating at the foot and at the northwestern side; the phosphate content of the investigated leachate samples was the highest at the foot of the landfill and amounted to 12.8 mg/dm3, which exceeds the MPC (10 mg/dm3) by 1.28 times; high concentration of ammonium nitride was discovered in the leachates at the foot (76.1 mg/dm3) and at the northwestern side (46.3 mg/dm3), which exceeds the MPC (30 mg/dm3) by 2.53 and 1.54 times, respectively; the highest indicators of total iron are typical for basins nearby (at the foot – 68.2 mg/dm3, at the northwestern side – 56.3 mg/dm3) and exceed the MPC norms (2.5 mg/dm3) by 27.28 and 22.52 times, respectively. According to certain indicators, the content of hazardous components in the leachates, which accumulate at the foot and at the northwestern side, exceeds the MPC and is several times higher than in the natural basins at the distance of 800 and 1200 m.
