Introduction: formaldehyde is an important chemical with many derivatives and commercial uses. Epidemiological studies of occupational population exposed to formaldehyde prove to be associated to biological effects in humans. Materials and methods: chromosome analyses were carried out in lymphocytes of 40 forensic doctors and dissectors male and female exposed to formaldehyde (FA) for 3 -20 years. A similar group of 40 males and females from the same police Institution but without FA exposure served as a control group with non exposure in order to establish frequency and different types of numerical and structural chromosomal aberrations. The exposed group to formaldehyde showed significantly increased incidence of breaks of the chromatid type, breaks of the chromosomes type, ring chromosomes and polyploidies was observed. Results: total mean exposure time to FA was about 3 times longer than non exposure group. The highest exposures to formaldehyde were encountered when autopsied cases were closed, followed by when autopsies cases were embalmed. Conclusions: the results demonstrate that exposure to formaldehyde induces chromosomal aberrations in peripheral blood lymphocytes of personnel working in murders of legal medicine departments.
