Photocopying machines are a common sight in the cities of India. There is ample evidence showing that the components of toners individually or in the form of a complex mixture are genotoxic. Toxic components of the photocopiers are from their emissions. toners and extremely low frequency electromagnetic fields (ELF-EMFs). In the present study micronucleus test (MNT) on buccal epithelial cells, cytokinesis block micronucleus (CBMN) assay and chromosomal aberration analysis on peripheral blood mononuclear cells was performed on 98 workers occupationally involved in photocopying and 90 age and sex matched controls. The results showed a significant increase in the frequency of MN in buccal epithelial cells and peripheral blood lymphocytes, as well as chromosomal aberrations in the exposed as compared to the control subjects.
