    Occupational exposure in ore mining workers significantly increased chromosomal aberrations (CA). Frequencies of CA were higher compared to reference groups, with no link to age, sex, or smoking.

    Area of Science:

    • Environmental Health
    • Occupational Medicine
    • Cytogenetics

    Background:

    • Ore mining and processing involve complex occupational hazards.
    • Workers may face significant exposure to genotoxic agents.
    • Chromosomal aberrations (CA) are indicators of genetic damage.

    Purpose of the Study:

    • To assess the frequency of chromosomal aberrations (CA) in ore mining and processing workers.
    • To compare CA frequencies in exposed workers with reference groups.
    • To investigate factors influencing CA levels, including age, sex, smoking, and length of service.

    Main Methods:

    • Studied 48 workers in ore mining and processing.
    • Analyzed frequencies of chromosomal aberrations (CA).
    • Compared exposed workers to control reference groups.

    Main Results:

    • Significantly increased frequency of CA observed in ore mining workers compared to reference groups.
    • The level of structural CA did not depend on age, sex, or smoking habits.
    • An indirect dependence was found between the frequency of cytogenetic disorders and length of service.

    Conclusions:

    • Ore mining and processing workers exhibit elevated chromosomal aberration rates due to occupational hazards.
    • Genetic damage indicators (CA) are influenced by duration of exposure in this occupational group.
    • Monitoring cytogenetic health is crucial for workers in hazardous environments.
