Description of key information

A 30 day BAF bioavailable value of 0.62 ± 0.11 was reported for silver nitrate bioaccumulation in the earthworm Eisenia fetida.

Key value for chemical safety assessment

BCF (terrestrial species):
0.62 dimensionless

Additional information

Coutris et al. (2012) used neutron activated soluble silver (silver nitrate) to assess the uptake, excretion and bio-distribution of silver in the earthworm Eisenia fetida exposed in standard OECD artificial soil (pH 5.95) amended with spiked, air dried, horse manure (0.55 ± 0.15 µg/g dissolved silver). A 30 day BAFbioavailable value of 0.62 ± 0.11 was reported.
