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

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.
