With a log Kow equal to – 2.19, Lead styphnate has notper sea potential for bioaccumulation. But given its observed potential to be eliminated from STP (by biodegradation ?), Pb is probably released as ion when the organic part is degraded. Therefore, Pb data can be used as reasonable worst-case for bioaccumulation assessment.

From the literature overview, the following bioaccumulation/bioconcentration factors have been derived for Pb:    

 - Aquatic compartment

Bioaccumulation/bioconcentration factors in freshwater: 1,553 L/kg

- Soil compartment

Bioaccumulation/bioconcentration factors in soil: 0.39 kg/kg (dry weight)
