Characterization of Leachate from Non-sanitary Municipal Solid Waste Landfill in Novi Sad

Abstract

Leachate is produced through complex chemical reactions, infiltration of the atmospheric water in the landfill body and the water contained in the waste, as well as through dissolution of waste pollutants. Due to its toxic composition, leachate pollutes soil and groundwater. It is very difficult to foresee real composition of landfill leachate due to dynamics of the processes occurring in the landfill body and the impact of a large number of variable factors. Qualitative composition of the leachate is characterized by pollutants that can be classified into four groups - soluble organic components, inorganic macrocomponents, heavy metals and xenobiotic organic compounds. The main objective of the conducted research was determination of the quality and organic profile of the leachate collected at non-sanitary municipal solid waste landfill in Novi Sad, by performing a screening analysis using GC-MS device.
