Description of key information

The mean BCF earthworm derived from a reliable dataset of 101 BAF valuesfor lead was 0.10 kg dw/kg ww. (dimension NOT Liter/kg ww)

Key value for chemical safety assessment

BCF (terrestrial species):
0.1

Additional information

Chromium

A range of values for uptake of chromium (VI) in earthworms is presented in the EU RAR and the mean of the middle of various ranges reported in literature was used to estimate the concentrations in worms. This mean BCF worm for chromium was calculated as 0.11 kg/kg ww.

Lead

A large amount of bioaccumulation data for terrestrial organisms is available as well for lead. The mean BCF earthworm derived from a reliable dataset of 101 BAF values was reported as 0.10 kg dw/kg ww.

However, it should be noted that the earthworm food chain was not addressed, neither in the EU RAR for chromium and nor in the vRAR for lead.
