Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Seven reliable chronic NOEC or EC10 values are selected for 3 annelid worm species, ranging from 130 mg Pb/kg dwv for hatching success of Dendrobaena rubida to 3000 mg Pb/kg dw for mortality of Eisenia fetida.
Similar toxicity tests are reported in different source documents (i.e. using the same organism, endpoint, soil and test conditions). For these cases, a geometric mean value is calculated. Two geometric mean values are calculated for tests with invertebrates.
• A geometric mean value is calculated based on 2 results for reproduction of Eisenia fetida in an OECD artificial soil (Spurgeon and Hopkin, 1995: NOECr = 608 mg/kg; Spurgeon et al., 1994: NOECr = 1822 mg/kg). The geometric mean is 1053 mg Pb/kg dw in the total risk approach.
• The second geometric mean value is calculated based on 2 results for reproduction of Eisenia fetida in a silt loam soil (Davies et al., 2002: NOECr = 400 mg/kg; Davies et al., 2003b: NOECr = 625 mg/kg). The geometric mean is 500 mg Pb/kg dw.
In total 5 NOEC or EC10 values for soft-bodied soil invertebrates are taken forward to the PNEC derivation.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
