Landfill leachates are potentially harmful to the environment and to human health.The objective of this study was to characterize leachates in order to analyze whether a relationshipexists between the stored waste and the composition of leachates, and to detect possible leakages ofpollutants into the environment. To achieve these objectives, field data, Global Positioning Systemdata and physico-chemical data were used. Biological tests are becoming increasingly popularin determining leachate toxicity; therefore, two toxicity tests were performed with the seeds ofwhite mustard (Sinapis albaL.) and duckweed (Lemna minorL.). Leachates were sampled from theleachate pond. Groundwater quality was monitored by using drill holes. The research and analysiscarried out are important to determine their potential impact on agricultural areas located near thelandfill. Demonstrably increased (P<0.05) concentrations of heavy metals were detected only inthe leachate pond which closes the landfill body, where it links up with the landfill insulation layer.Water sampled from drill holes reaching into groundwater was not contaminated. The results showedthat the leachates did not leak outside the landfill. Nevertheless, they were found to be phytotoxic.Both toxicity tests showed that the increasing amount of leachates resulted in the increasing growthinhibition of the tested plants. The proper handling of leachates should have been ensured.
