Aim: The most important industrial use of carbon disulfide (CS2 ) has been in the fabrication of regenerated cellulose rayon by the viscose process and cellophane. CS 2 leads to increased frequency of chromosomal aberrations in workers with occupational exposure to CS 2 . Methods: In the present study, the DNA damage was analyzed by using buccal cell comet assay for 30 viscose plant workers who are occupationally exposed to CS 2 and 30 healthy individuals. Both groups were classified as smokers and non-smokers and only the experimental subjects were classified based on the exposure period. The data were analyzed statistically by the Student′s t-test. Results: The results of this study showed increased levels of DNA damage among viscose plant workers. Conclusion: The habit of cigarette smoking among the viscose workers had a synergistic effect on inducing DNA damage.
