Bioaccumulation: aquatic / sediment

Description of key information
Bioaccumulation is not applicable to the target compound itself but to single PAHs, i.e. benzo[a]pyrene (BaP).Key value for chemical safety assessment
- BCF (aquatic species):
- 608 dimensionless
Additional information
The BCF in fish of 608 (sunfish: Lepomis macrochirus) relates to benzo[a]pyrene. It was the only value of a study among 13 published investigations to be given the high reliability of 2 in the risk assessment report for Pitch, coal tar, high temp. [CAS no. 65996-93-2] (EU 2008, Tab. 3.28). This value is in line with an unpublished fish feeding study (rainbow trout: Oncorhyncus mykiss): BCF = 977 with a very short depuration half-life of 1.1 d (Lampi et al. 2009: CONCAWE review).
This suggests that the BCF of benzo[a]pyrene should be distinctly below 2000.
