Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Median BAF observed on earthworms is 15 (expressed on a dry weight basis). For arthropoda, the median BAF is 1.4 (summary from the EU risk assessment, ECB 2008). The BAF observed in Cd-contaminated or Cd-enriched soils is lower than the BAF observed in control soils. In a field study, the BAF observed under contaminated conditions on Lumbricus rubellus was 12-123, under control conditions it was 190.
Key value for chemical safety assessment
Additional information
The EU Risk assessment (ECB 2008) presents BAF values that were calculated from the soil:biota concentration ratio’s. Most organisms are earthworms and the Cd levels were expressed on dry or wet weight basis. All the data on earthworms were obtained from specimens with guts voided prior to analysis.
Cadmium is concentrated from the soil into earthworms organisms (BAF values are all higher than 1). Most important factors affecting the bioaccumulation of Cd by earthworms are the Cd concentration of the soil, soil type, pH, soil organic matter and CEC.
The influence of the Cd content of the soil on the bioaccumulation of Cd is illustrated in most of the studies. Cadmium concentrations in earthworms increase with increasing Cd levels in a non-proportional way. As a result, the BAF observed in Cd-contaminated or Cd-enriched soils is lower than the BAF observed in control soils.
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.
