Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
There are 18 reliable NOEC or EC10 values selected for 5 different functional parameters for microbial processes. The functional parameters comprise C- and N-mineralization. The selected NOEC and EC10 values on functional parameters vary from 96 to 4144 mg Pb kg-1 (both values observed for respiration). Additionally, 20 NOEC or EC10 values are selected for 8 different enzyme assays, ranging from 132 mg Pb kg-1 for dehydrogenase to 16576 mg Pb kg-1 for phosphatase. The ecological relevance of reduced enzymatic activities is unclear and, therefore these data re not used for PNEC calculation, but only presented as supporting evidence.
Key value for chemical safety assessment
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.
