Abstract: Polybrominated Diphenyl Ethers (PBDEs) are used as flame retardants in plastics, textiles, electrical components and other materials to slow the ignition and spread of fire. PBDEs bioaccumulate in blood, breast milk, and fat tissues and they show association with endocrine disruption, reproductive toxicity, and developmental neurotoxicity in rodent studies. The total PBDE concentration in landfill leachate is reported to be up to about 1,500 ng/L. In this study the sorption of PBDE to high-density polyethylene (HDPE) geomembrane is examined by performing sorption laboratory tests. Techniques to be used for assessing the diffusive properties including partitioning, diffusion and permeation coefficients of the geomembrane are discussed.
