Description of key information

BCF of Atlen SK is 1209.

Key value for chemical safety assessment

BCF (aquatic species):
1 209 dimensionless

Additional information

Atlen SK was not tested with respect to bioaccumulation. Reported BCF value was calculated on the basis of octanol/water partition coefficient of Atlen SK using bilinear equation proposed by Kubinyi and given in the document 'Guidance on information requirements and chemical safety assessment Chapter R.7c: Endpoint specific guidance' (version of May 2008, section R., p. 18).


log BCF = 0.85 × log Kow − 0.70

logKow = 4.45

log BCF = 3.0825

BCF = 1209
