Characterisation of the efficiency of leachate treatment methods when considering different
groups of pollutants as phenolic compounds, PCB,s, PBDEs and phthalates is discussed.
Strategies for measurements, identification and quantifications of the organic pollutants are
presented and the use of supported liquid membrane extraction (SLM) and micro porous
membrane extraction (MMLLE) in particular, where small and medium molecules are
separated from large molecules. Acute and chronic toxicity tests by biological methods and
the choice of organisms are also presented as well as the LAQUA-protocol used at the pilot
plant in Kristianstad, Sweden. In acute toxicity tests of the leachate a clear accommodating on
the immobility of the Artemia larvae and increasing concentration of leachate was noted.
Different species react different on different compounds and therefore on complex effluents
as landfill leachates the use of a battery of bioassays is recommended.
