Molybdenum and selected inorganic molybdenum compounds

Molybdenum is a mineral found throughout nature that serves as a nutrient for humans, plants, and animals. Molybdenum is also used in the metal industry, for example in the production of cast iron and stainless steel. Occupational exposure occurs when molybdenum is released into the air during industrial processes.

The Health Council’s subcommittee on Classification of Substances Toxic to Reproduction advises the Ministry of Social Affairs and Employment not to classify molybdenum for effects on fertility, the development of offspring, or for effects on or through breastfeeding. According to the committee, there is a lack of relevant data for classification. 

The committee also evaluated the potentially hazardous properties of a group of inorganic molybdenum compounds. The committee advises not to classify these compounds for effects on fertility or the development of offspring, because the available data do not justify classification. The committee advises not to classify the group of compounds for effects on or via lactation, due to a lack of relevant data.
