Description / Abstract:
This International Standard 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 availability.
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 1 000 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.
