摘要：The research of 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 biggest 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 salted leachates with chlorides and sulfites are those accumulating at the foot and at the northwestern side; phosphates content of the investigated samples of the leachates was the highest at the foot of the landfill and it was 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, accordingly; 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.
