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

Two reliable feeding studies with birds using sodium molybdate as test substance have been identified. The 28 day study by Davies et al (1960), reported a NOEC of 400 mg Mo/kg. A more recent 30 day study by Stafford et al (2016) with bobwhite quail resulted in comparable NOAEC of 134 mg Mo/kg bw/day. The effects that were noted at higher concentrations levels, however, proved to be reversible.

These studies indicated that birds have a similar sensitivity as rats.
