This document specifies an extraction method to determine the bioavailable (potential and environmental available) fraction and the non-bioavailable fraction of a contaminant in soil using a “receiver phase” for an organic contaminant with strong sorbing or complexing properties, for example, Tenax®1) or cyclodextrin, respectively. NOTE 1 The bioavailable fraction is defined in ISO 17402 as environmental bioavailability. The method is applicable for non-polar organic contaminants with an aqueous solubility of <100 mg/l. The method is applicable for soil and soil-like material including (dredged) sediments. NOTE 2 The method is theoretically applicable to non-polar organic contaminants with an aqueous solubility of 1000 mg/l. The method has been often applied for compounds with a much lower solubility (Kow > 3) and less for compounds with a higher solubility. The applicability is therefore defined for compounds with an aqueous solubility of <100 mg/l.
