Environmental hazard of Novoyavorivsk municipal landfill

Abstract

Novoyavorivsk is located near large sulfur deposits in a transborder with Poland. The existing sanitation system in Novoyavorivsk is imperfect. Municipal wastes are stored in cloughs, ravines, river valleys. This causes an environmental hazard, as polluted wastewater is discharged to the water bodies. The aim of the work is environmental hazard assessment of Novoyavorivsk landfill. The tasks of the research are as follows: determination of chlorides and sulfates content in the landfill edaphotopes; measurement of power of equivalent dose of photon radiation. Determination of chlorides and sulfates was carried out by quantitative and qualitative methods. The equivalent dose of photon radiation was measured by dosimeter by SOEKS USA, LLC. In different sites of the landfill chlorides and sulfates content differs. The most polluted areas are at the distance of 10 m and 50 m from the foot. At a distance of 100 m from the landfill, the concentration of chlorides reduces to 0.001% (5 cm) and 0.1% (10 cm and 20 cm). High sulfate content is observed at 10 m from the foot of the landfill (1% in the 10 cm and 20 cm horizons). The power of the equivalent dose at a height of 10 m from the south side exceeds the pollution standard of 0.3 μSv/h and equals 0.32 μSv/h.
