Description of key information

A measured BCF is not available for any streams in this category. Non-polar substances have been shown to have a linear relationship between log Kow and BCF in the log Kow range 1 - 6. Several QSAR models have been developed that calculate the BCF of non-polar, hydrophobic compounds on the basis of their log Kow (e.g. Veith et al, 1979 and USEPA, 2008). The most of the substances in streams of this category fall within the applicability domain of these models. For the substance with a log Kow >6, a parabolic method has been used for calculation. BCF have been calculated for various representative components of these streams. The calculated values range from 39 to 18220 (USEPA 2008) and 57.5 to 162181 (Veith 1979).
