A bioassay-directed method for the separation of volatile compounds from landfill leachates

A bioassay-directed method for the separation of volatile compounds from landfill leachates based on a destillation in a closed system is presented. The method supplies a volatile fraction containing compounds with Henryʹs law constants down to 0.01 (20°C) concentrated in destilled water, which can be investigated directly using bioassays and chemical analysis.
