Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
In the International Molybdenum Association soils project, a total of 10 topsoils with contrasting properties that may affect the toxicity of Mo in soil were collected and on each of these soils a series of 11 toxicity tests was performed after spiking with Na2MoO4(5 plant assays: root elongation for barley and shoot yield for Oilseed rape, Red clover, Ryegrass and Tomato; 3 invertebrate assays: reproduction fo rEnchytraeus crypticus, Eisenia andrei and Folsomia candida; and 3 microbial assays: nitrification, glucose induced respiration and mineralisation of plant residues). For the invertebrates, ecotoxicity tests were also conducted on an OECD artificial soil.
Additionally, 3 soils were aged outdoors after spiking with sodium molybdate. After 6 and 11 months, subsamples were collected and the 10 ecotoxicity tests (same as above, without barley root elongation assay) were conducted on these soils.
All data were based on added mg Mo/kg dw soil.
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.
