Municipal solid waste landfills are mostly bordering on rural areas and may to cause the environmental degradation. Therefore, the issue of monitoring and assessment of negative landfill impact on bordering areas, including agricultural land, is relevant. The aim of the study is monitoring and assessment of landfill impact on air pollution, soil contamination, pollutants content of leachate from landfills. Monitoring of air pollution was measured on the soil sites situated at the landfill, at the border between landfill and agricultural areas, at the distance of 200 m from the landfill. The following pollutants were investigated: CO2 , NO2 , NH3 , H2S, C7H8, C8H10 dust. Monitoring of soil contamination was measured at the border between landfill and agricultural areas; at the distance of 50, 100, 200 and 500 m from the landfill. The following pollutants were investigated: Pb, Hg, Cu, Zn, petroleum products. Monitoring of leachate pollution was conducted by following pollutants: NO2-, NO3-, NH4, SO42-, Cl-, Fe, Cu, Pb, Zn, Ni, PO43-, petroleum products, surface active substance. Sampling of the leachate was carried out at the territory of the landfill. The results of our study show that 90% of studied landfills are in close proximity to agricultural land and have technogenic impact on the bordering areas. The assessment of landfill impact on atmospheric air established the exceeding of MPC of all investigated pollutants at the border between landfill and agricultural land. Exceeding of the MPC of pollutants in atmospheric air at a distance of 200 m and more have not been established. The assessment of landfill impact on soil contamination established the exceeding of MPC of heavy metals and petroleum products at the border between landfill and agricultural land and at a distance of 50 m and 100 m from landfills. Exceeding of the MPC of heavy metals and petroleum products in the soil at a distance of 200 m and more has not been established. The results of the assessment of leachate from landfill sites show the exceeding of MPC of investigated pollutants for 60% studied areas. This creates an additional chemical load on groundwater, soils and can lead to decreasing the quality of agricultural products which grown in technogenic pressured areas. Thus, our research confirmed the existence of a threat to environmental and food security on areas, bordering on the landfills.
