- Definition the concentration of test substance in/on an organism or specified tissues thereof (Cf as μg/g (ppm)) divided by the concentration of the chemical in the surrounding medium (Cw as μg/ml (ppm)) Reference "Council Regulation (EC) No 440/2008 laying down test methods pursuant to Regulation (EC) No 1907/2006 of the European Parliament and of the Council on the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) CELEX:32008R0440/EN"
- Comment "Since chemical sorption to particulate and dissolved organic substance in the water column may substantially reduce the fraction of the chemical in the water that can actually be absorbed by aquatic organisms, the BCF can also be defined in terms of the freely dissolved chemical concentration (CWD), as BCFP :BCFP = CB / CWD Not to be confused with bioaccumulation factorRef.: Manuela Pavan, Andrew P.
