Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Water solubility was determined to be 185 mg/L at 20°C (study result, EU A.6 method), based on the average of 10 samples - however it should be noted that the average pH of these samples was 10.96.

Transformation dissolution data are available for both Pb metal powder (24hr screening at pH6, pH7 and pH8, 7- and 28 -day full T/Dp at pH6 and pH8) and Pb metal massive (7 and 28 day at pH6, pH7 and pH8).

Key value for chemical safety assessment

Water solubility:
185 mg/L
at the temperature of:
20 °C

Additional information

Water solubility was determined on Pb powder; full T/Dp data are available for Pb massive, and a T/Dp screening study and 7- and 28 -day full T/Dp at ph6 and pH8 for Pb powder.
