The International Agency for Research on Cancer (IARC), the cancer agency of the World Health Organization, has evaluated the carcinogenicity of five chemical agents: pentachlorophenol, 2,4,6-trichlorophenol, 3,3′,4,4′-tetrachloroazobenzene, aldrin, and dieldrin. A summary of the evaluations has now been published in The Lancet Oncology. The detailed assessments will be published as Volume 117 of the IARC Monographs.
