WebHowever, at very high log Kow (>6), a decreasing relationship between the two parameters is observed. The aquatic BCF of a substance is probably lower than 2000 L/kg if the calculated log Kow is higher than 10 (i.e. a log Kow >10 is taken as an indicator for showing reduced bioconcentration). WebA general model was presented in section 6.1, Eq. (24)[134]. The largest data set was described by Korzerski et al [186], which is reasonably representative of models for soils with high organic ...
