IARC revised "Monographs on Identification of Carcinogenic Hazards to Humans" website (Volumes 1-131)
11 April 2022
The International Agency for Research on Cancer (IARC), the cancer agency of the World Health Organization, revised its website "IARC Monographs on the Identification of Carcinogenic Hazards to Humans" https://monographs.iarc.who.int/agents-classified-by-the-iarc/ on 8 April 2022.
This revision is to notify the publication of the full paper (online version) of "Monographs Volume 131: Cobalt, antimony compounds, and weapons-grade tungsten alloy".

For all agents, exposures are expected to be higher in occupational situations than in the general population.
The Working Group classified trivalent antimony as probably carcinogenic to humans (Group 2A) on the basis of limited evidence of carcinogenicity in humans, sufficient evidence of carcinogenicity in experimental animals, and strong mechanistic evidence in human primary cells and in experimental systems. Cobalt metal and soluble cobalt(II) salts were classified as probably carcinogenic to humans (Group 2A) on the basis of sufficient evidence in experimental animals and strong mechanistic evidence in human primary cells. Cobalt(II) oxide and weapons-grade tungsten alloy were classified as possibly carcinogenic to humans (Group 2B) on the basis of sufficient evidence in experimental animals. Cobalt(II,III) oxide, cobalt(II) sulfide, other cobalt(II) compounds, and pentavalent antimony were each evaluated as not classifiable as to its carcinogenicity to humans (Group 3).
* Note from JEIC:
There is no change in the carcinogenic hazard categories for EMFs.
