Description of key information

No bioaccumulation experimental studies are known to have been undertaken. Therefore Bioconcentration Factors (BCF) have been estimated using EPI Suite, based on a log Kow of 13.9396, and using the regression-based and Arnot-Gobas methods.

Key value for chemical safety assessment

BCF (aquatic species):
5.29 L/kg ww

Additional information

No bioaccumulation experimental studies are known to have been undertaken. Therefore the following Bioconcentration Factors (BCF) have been estimated using EPI Suite, based on a log Kow of 13.9396, and using the regression-based and Arnot-Gobas methods:

Regression-based method:

o       Log BCF:  0.72  (BCF = 5.29 L/kg wet-wt)

Arnot-Gobas BCF & BAF Methods (including biotransformation rate estimates):

o       Log BCF (upper trophic) =  -0.045  (BCF = 0.9017 L/kg wet-wt)

o       Log BAF (upper trophic) =  1.645  (BAF = 44.2 L/kg wet-wt)

o       Log BCF (mid trophic)   =  -0.025  (BCF = 0.9447 L/kg wet-wt)

o       Log BAF (mid trophic)   =  1.293  (BAF = 19.64 L/kg wet-wt)

o       Log BCF (lower trophic) =  -0.020  (BCF = 0.9552 L/kg wet-wt)

o       Log BAF (lower trophic) =  1.029  (BAF = 10.7 L/kg wet-wt)

Arnot-Gobas BCF & BAF Methods (assuming a biotransformation rate of zero):

o       Log BCF (upper trophic) =  -0.044  (BCF = 0.9028 L/kg wet-wt)

o       Log BAF (upper trophic) =  1.704  (BAF = 50.61 L/kg wet-wt)
