Objectives:
The study was performed to know about the extent of occupational DNA damage in photocopiers’ workers.
Methods:
Blood samples were collected from 136 exposed group and 74 control group. Comet assay was performed to assess the DNA damage caused by emissions from photocopiers.
Results:
The results indicated that there was a significant increase (P < 0.05) in DNA damage in persons working in photocopiers (122.1 ± 60.7) than the controls (56.6 ± 17.2). Duration of occupational exposure had positive correlation (r = 0.793, P
< 0.001) with DNA damage. Age had significant effects on the total comet score (TCS) of the exposed group as compared to the control group (P < 0.05).
Conclusions:
In conclusion, these findings indicate significant genotoxicity in photocopiers’ workers.
