Objective: This study was conducted to evaluate the frequency of chromosomal aberrations in peripheral blood lymphocytes from Palestinian males exposed to various chemical pollutants during their daily work. Subjects and Methods: The study population consisted of 32 males (mean age 35.5 years) distributed as: 14 farmers, 3 plumbers, 5 taxi drivers, 6 paint factory workers, and 4 gas station workers, exposed to pollutants like pesticide, petrol derivatives etc. The control group consisted of 10 healthy Palestinian individuals of the same age and gender, but not exposed directly to pollutants in their jobs. Chromosomes were prepared from peripheral blood lymphocyte cultures using standard methods. The evaluation of chromosomal aberrations was performed following the IPCS (International Program Chemical Safety) guidelines for the monitoring of genotoxicity effects of carcinogens in humans. Results: A significantly higher incidence (2.14%, p<0.05) of chromosomal aberrations (chromatid breaks, iso-chromatid breaks, chromatid deletions, and acentric fragments) were detected in lymphocyte of the study population. Interestingly, no chromosomal damage at all was recorded in the control group lymphocyte. Conclusion: These results suggest that occupational exposure to chemical pollutants is the cause of the chromosomal aberrations observed in the study population, which could be related to exposure time, since chromosomal aberrations were more frequent in workers exposed for longer times. The increased chromosomal damage detected in the study population can be attributed to the complex mixture of genotoxic compounds to which this group has been exposed.
