Abstract This review documents current knowledge on the potential occupational health effects, mainly on the central nervous system, following occupational exposure to manganese. This metal is present in high concentrations in the air in mines and foundries. Claims have also been made to the Quebec Occupational Safety and Health Commission (CSST) by workers exposed to this substance during welding operations involving steel containing manganese. The report describes processes of assimilation of manganese by the body, its biomarkers and its effects on health. It also compares different organizations' standards and guideline recommendations. Current Quebec standards are similar to those of the United States, the United Kingdom and Australia. Organizations and groups of researchers in this field recommend making them more restrictive in order to take into account the early effects on the central nervous system.
