Table 1 Occupational agents, groups of agents, mixtures, and exposure circumstances classified by the IARC Monographs, Vols 1–77 (IARC, 1972–2001), into Groups 1 and 2A, which have the skin as the target organ and for which burden has been estimated

From: Occupational cancer in Britain

Agents, mixture, circumstance Main industry, use Evidence of carcinogenicity in humans Source of data for estimation of numbers ever exposed over REP Comments
Group 1: Carcinogenic to humans
Agents, groups of agents
Mineral oils, untreated and mildly treated Production; used as lubricant by metal workers, machinists, engineers; printing industry (ink formulation); used in cosmetics, medicinal and pharmaceutical preparations NMSC sufficient LFS In addition includes shale oils or shale-derived lubricants
Solar radiation Outdoor workers NMSC sufficient
Melanoma sufficient
Coal tar and pitches (Polycyclic aromatic hydrocarbons) Production of refined chemicals and coal tar products (patent fuel); coke production; coal gasification; aluminium production; foundries; road paving and construction (roofers and slaters) NMSC sufficient LFS In addition includes soots, and creosotes
Group 2A: Probably carcinogenic to humans
Agents, groups of agents
Ultraviolet radiation (A, B and C) from artificial sources Arc welding; industrial photoprocesses; sterilisation and disinfection; phototherapy; operating theatres; laboratories; ultraviolet fluorescence in food industry; insect traps Melanoma of skin inadequate   Predominantly harms the eyes thus calculated for melanoma of the eye only
