NOTE 1 The bioavailable fraction is defined in ISO 17402 as environmental bioavailability.
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.
BSI recommends this version of standard for organisations operating in or with the UK. The ISO edition is available here if required.
