Cytogenetic monitoring of chemical workers in production of the drug 1-propoxy-2-acetamino-4-nitrobenzol with reference to their smoking habits.
The induction of chromosome aberrations (CAs) and sister-chromatid exchanges (SCEs) was examined in cultured lymphocytes from 23 individuals employed in the production of the drug 1-propoxy-2-acetamino-4-nitrobenzol. Lymphocytes of workers were cultured before and 13 weeks after starting professional activity. The latter showed a significant increase in both CAs and SCEs. Smokers (11 individuals) and non-smokers (12 individuals) were indistinguishable with respect to the frequencies of CAs or SCEs before starting professional activity, 13 weeks later smokers exhibited significantly more SCEs than non-smokers. This strongly suggests a comutagenic interaction of cigarette smoke and exposure to chemicals during drug production. On the basis of the technology applied the compound inducing CAs and SCEs in lymphocytes of smoking workers seems to be 2-acetamino-4-nitrophenol.
