||Integrating studies on carcinogenic risk of carbon black: Epidemiology, animal exposures, and mechanism of action
||Dec. 2006, Vol.48, No.12, p.1291-1307. 76 ref.
||In this literature survey on the toxicology of carbon black (CB), epidemiology and laboratory studies were reviewed from 1996, when IARC classified carbon black as a group 2B carcinogen (probably carcinogenic to humans). Findings are discussed. High levels of inhaled CB were linked with rat lung tumours in 1996, but today scientists increasingly recognize that rats exhibit a unique lung tumour response to all inert inhaled particles that is unlikely to be relevant to humans. Toxicity in rats results from the particle overload, and not from the particles' chemistry. Research published after 1996 has not identified an increase in support for CB cancer risk, but rather, points to limited and inadequate evidence for carcinogenicity. Overall, the new epidemiological evidence decreases concerns for cancer risk compared with pre-1996 evidence.
