Leaching occurs when soluble organic and inorganic components are dissolved out of a solid material by percolating water. The leachate in landfills ultimately leak, percolate and could contaminate the groundwater. Hence its analysis can be an indication of environmental pollution. The main objectives of the study were the characterization and identification of major pollutant parameters in leachate samples from municipal waste landfills in Vojvodina region (Novi Sad, Subotica, Kikinda and Zrenjanin). All water samples had low concentration levels of dissolved oxygen (from 0.03 to 0.21 mg/L), except water samples from non sanitary landfill in Zrenjanin which indicates high organic contamination of water samples. High values of BOD^sub 5^ of the samples from sanitary landfill (784 - 1275 mg/L) show high pollution of leachate water with biodegradable organic matter. Better quality of some leachate samples from non sanitary landfills has shown signs of aerobic degradation and also there is dilution factor that highly affects quality of water samples. Obtained results show that Ni^sup 2+^ is the most predominant metal in the landfills (0.591 - 5.029 mg/L). Zn^sup 2+^ was found as the most abundant at the sanitary solid waste landfill (1.444 - 1.517 mg/L). Concentration levels of the toxic cadmium were under the limit of detection, 0.02 mg/L, in all samples. The obtained results indicate low water quality of samples collected from sanitary and non sanitary municipal waste landfills. Because non sanitary landfills don't have impermeable bottom layer, there is presence of high risks for contamination of soil, surface and ground water in Vojvodina area. This type of field investigation of the quality of landfill leachate in Vojvodina was conducted for the first time. [PUBLICATION ABSTRACT]
