RT Journal Article SR Electronic T1 A retrospective mortality study of substituted anthraquinone dyestuffs workers JF British Journal of Industrial Medicine JO Br J Ind Med FD BMJ Publishing Group Ltd SP 355 OP 360 DO 10.1136/oem.39.4.355 VO 39 IS 4 A1 Gardiner, J S A1 Walker, S A A1 Maclean, A J YR 1982 UL http://oem.bmj.com/content/39/4/355.abstract AB ABSTRACT Because short-term bacterial tests have previously shown that about one-third of substituted anthraquinones tested are capable of causing reverse mutation, and two-year feeding studies of three such dyestuffs in rats have shown an excess of hepatocellular carcinomas, a retrospective cohort mortality study was carried out on a population of 1975 male workers employed in a dyestuffs manufacturing plant in Scotland. The population was identified as having worked for more than six months within the factory during the decade 1 January 1956-31 December 1965, and their mortality experience was followed up to 30 June 1980. Age-standardised mortality rates did not show any excess in total or cancer-related mortality.
