Another study reporting CA in lymphocytes from car painters in Brazil showed that there was a significantly higher frequency of aneuploidies and chromosome deletions in the peripheral lymphocytes of car painters than in control subjects.[ 29 ] The MN test and the Comet assay were applied to exfoliated buccal cells in order to evaluate the genotoxic risk associated with occupational exposure of 10 car painters by Martino-Roth et al .[ 30 ] Highly significant effects of occupational exposure were found in this study with both the MN test and the Comet assay.
