Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Based on a log Pow of 4.93 (Pow = 83,180), the BCF for earthworm was estimated following the procedure described in the Technical Guidance Document (EC 2003, part II) (see below).
Key value for chemical safety assessment
- BCF (terrestrial species):
- 1 000 L/kg ww
Additional information
According to Guidance on IR&CSA - Chapter R.16: Environmental Exposure Estimation, R.16.6.7.2 (p. 91), bioconcentration in earthworm can be described for organic substances as a hydrophobic partitioning between the pore water and the phases inside the organism. This equilibrium partitioning approach can be modelled according to the following equation as described by Jager (1998):
BCFearthworm= (0.84 + 0.012Pow) / ROHearthworm
where for ROHearthwormby default a value of 1 (kg wwt/L) can be assumed.
The Pow used for AOH is estimated to be 4.92 (see Chapter 1.3 - Partition coefficient).
BCFearthworm= (0.84 + 0.012 x 83,180) / 1
= 999 L/kg ww
