Description of key information
Bioaccumulation/bioconcentration factors in soil: 0.39 kg/kg (dry weight)
Key value for chemical safety assessment
Additional information
Bioaccumulation factors (BAFs) for Pb from to soil to earthworms are summarised in the voluntary risk assessment of lead, VRAL(LDAI, 2008). A median BAF for earthworms on a dry weight basis is 0.39 kgdw/kgdw (median of 101 values) and 10-90thpercentiles are 0.13-1.17. On a fresh tissue weight basis, BAF values are 0.10 kgdw/kgww(median) and 0.03-0.27 (10-90thpercentiles). The influence of soil properties on the BAF of earthworms (A. calluginosa) was studied in different soils and the equation describing the BAF as a function of pH reads, with BAF on a wet weight basis (kgdw/kgww)
BAF=13.9*exp(-0.76*pH)
(Ma, 1982). This equation predicts that the median BAF of the 101 data points above (BAF= 0.10 kgdw/kgww) is found at pH=6.5. At pH 4.5, this BAF is 4-fold larger. There is no significant effect of total soil Pb on the BAFs (LDAI, 2008).
A few literature data are available for bioaccumulation of Pb in isopods from soil or litter, 14 BAFs were collected and listed inTable12. Values range from 0.001-0.65 kgdw/kgdw. A median BAF for isopods on a dry weight basis is 0.04 (median of 14 values).
Table14: Bioaccumulation factors between soil or decomposed leaf litter and isopods. The Pb concentrations in the biota are the product of BAF and soil Pb concentration.
