“…The Buccal Micronucleus Cytome Assay (BMCA) is regarded as a suitable test for risk assessment associated with chemical induction of DNA damage [19,20]. A strong correlation between the rate of nuclear anomalies and diseases like cancer and neurodegenerative diseases was demonstrated in several studies [21,22]. Thus, BMCA is a suitable method to detect the genotoxic and short-termexposure-related-cytotoxic damage in human tissues, which are targeted by potential carcinogens [23].…”

Banana farming represents an important segment of agricultural production in Ecuador. The health of farmworkers might be compromised by the extensive use of pesticides in plantations applied under poorly regulated conditions. Due to an increased awareness of pesticide-related problems for nature, as well as for worker and consumer health, ecological farming has been established in some plantations of Ecuador. We set out to investigate the occupational health of workers in both conventional and ecological farming. Nuclear anomalies in buccal epithelial cells were used as short-term indicators for genotoxicity and a potentially increased cancer risk in the two groups of farmworkers. By application of the Buccal Micronucleus Cytome Assay (BMCA), we found the frequency of micronuclei in conventional pesticide using farmworkers significantly increased by 2.6-fold, and other nuclear anomalies significantly increased by 24% to 80% (except pyknosis with a non-significant increase of 11%) compared to the farmworkers on ecological plantations. These results demonstrate that ecological farming may provide an alternative to extensive pesticide use with significantly reduced indicators of cancer risk. In conventional farming, improvements in education and instruction regarding the safe handling of pesticides and protective equipment, as well as regulatory measures, are urgently needed.

In general, an occupation could have hazzard and risk of exposure to genotoxic chemical compounds. These compounds could lead to micronucleus formation on buccal mucosa. This study was aimed to obtain the impact of chemical exposure on micronucleus formation in buccal mucosa at various occupations. This was a literature review study using databases of PubMed, ScienceDirect, and Google Scholar based on the keywords. The criteria of literatures were articles published in 2016-2021 using Indonesian or English language. The results showed that group compounds of polycyclic aromatic hydrocarbons (PAH), metals, carbamate, and organophospate, also compunds of silica, bezene, toluene, xylene (BTX), sevoflurane, desflurane, isoflurane, nitrous oxide, gemcitabin, and 5-fluoro uracil were genotoxic chemical compunds and could cause micronucleus formation in buccal mucosa of mechanics, grillers, miners, e-waste recyclers, construction workers, road markers, car painters, gasoline station workers, farmers, and healthcare workers. Genotoxic chemical compounds could be found excessively in occupational environment. These compounds could damage cells’ DNA and caused micronucleus formation on buccal mucosa of workers. It is suggested to study further about cell damage biomarkers caused by genotoxic chemical compound exposure.Keywords: micronucleus formation in buccal mucosa, chemical exposure of genotoxic compounds, occupational riskAbstrak: Suatu pekerjaan dapat memiliki risiko dan bahaya terpapar senyawa kimia yang bersifat genotoksik.

“…Significant differences in the frequency of MNi have been demonstrated, for example, in women agricultural laborers with respect to an unexposed group 58 , while workers on banana plantations showed an increase in the frequency of micronuclei when compared to unexposed controls 59 . A study carried out with greenhouse workers found significant differences in nuclear alterations (MNi, BN,PK, KR) compared to a group that was not exposed to pesticides 60 ; however, those studies did not conduct analyses of pesticide concentrations that might reveal a direct association, but only considered potential exposures based on a list of the pesticides utilized.…”

This study identified and determined organochloride pesticide (OCs) concentrations in hair samples from children at two elementary schools: one exposed to fumigations in agricultural fields, the other unexposed. Three concentrations of OCs levels in the hair were compared (high, medium, low), and total nuclear abnormalities in buccal cells were determined: micronuclei (MNi), condensed chromatin, karyorrhexis, pyknosis, binucleate cells, karyolysis, lobed nuclei, and apoptosis. No significant differences were found for the presence of MNi between the schoolchildren from the exposed and unexposed schools, but the prevalence of OCs in both schools was over 50%, as well as the frequencies of MNi in the children were over 58%. Findings show a significant difference between the frequency of MNi in the total sample of schoolchildren (exposed school + unexposed school) in relation to the concentration of OCs detected in their hair. The children from exposed school that showed the higher concentrations of OCs in hair had higher levels of genotoxic damage in the buccal cells; compared against children with lower concentrations of OCs. The most frequent nuclear abnormalities in the exposed children were lobed nuclei (79.4%), binucleate cells (66.66%), apoptosis (65.07), and MNi (58.7%). We determined the prevalence ratio (PR) and prevalence odds ratio (POR) for the presence of MNi in buccal cells in relation to the OCs concentrations in the hair samples. Both ratios were high for MNi [PR 3.93, 95% confidence interval (CI) 1.97–7.84, p = 0.0003; and POR 7.97, 95% CI 2.62–24.28, p = 0.0003], indicating a 7.97 times greater risk that the exposed children will present > 0.2% of MNi when OCs concentrations exceed 0.447 μg/g. These indicators may be useful biomarkers of genotoxic damage in children exposed to persistent, highly-toxic compounds. Results suggest the potential risk to which those schoolchildren are exposed on a daily basis due to fumigations in nearby agricultural fields.
