Description of key information
Bioaccumulation/bioconcentration factors in freshwater: 1,553 L/kg
Key value for chemical safety assessment
- BCF (aquatic species):
- 1 553 L/kg ww
Additional information
Bioconcentration (BCFs) and bioaccumulation factors (BAFs) for Pb from water to aquatic invertebrates and fish were summarised in the voluntary risk assessment of lead, VRAL (LDAI, 2008).
Within typical environmental concentration range, the gathered BAFs for fish ranged between 11 and 143 L/kgww(10 – 90th%) with a median value of 23 L/kgwwwhile the BAFs for molluscs ranged between 18 and 3,850 L/kgww(median value of 675 L/kgww), for insects between 968 and 4,740 L/kgww(median value of 1,830 L/kgww) and for crustaceans between 1,583 and 11,260 L/kgww(median value of 3,440 L/kgww)

According to the VRAL (2008) a mixed diet scenario is assumed, considering that birds/mammals consume equal proportion of the different food types. Based on significant high bioaccumulation in molluscs, secondary poisoning was also considered for a “mollusc food chain”. The range of bioaccumulation factor (BAF in L/kgww) of Pb in the mixed and mollusc food diet is presented below.

This table shows that the 50th% of the mixed diet BAF for aquatic organisms is 1,553 L/kg (90th%: 3,890 L/kg) and that the mixed diet scenario is driven by the BAF values retrieved from the invertebrates. The 50th% BAF of the mollusc food diet is somewhat lower, i.e. 675 l/kg (90th%: 3,850 L/kg). The BAF value of 1,553 L/kg is further used for the assessment of the secondary poisoning in the aquatic environment.
