An increased incidence of nasal squamous cell carcinomas was observed in long-term inhalation studies in rats and in mice. The classification is supported by in vitro genotoxicity data and formaldehyde's structural relationships to other carcinogenic aldehydes such as acetaldehyde.

There is limited evidence in humans for the carcinogenicity of formaldehyde. There is sufficient evidence in experimental animals for the carcinogenicity of formaldehyde.

The questionnaires were given to a cohort of 1st-yr medical students on completion of the gross anatomy lab course. Air sampling of formaldehyde levels in the anatomy labs was carried out on one day during the time in which these students were conducting dissections. Although the results of the air sampling showed formaldehyde levels to be well below current occupational standards, significant numbers of students reported experiencing symptoms associated with formaldehyde exposure.

Estimates of the relative risk of experiencing formaldehyde-related symptoms in the anatomy laboratories compared to the control laboratories ranged from 2. In addn, it was found that female students were 3 times more likely to report formaldehyde-related symptoms than male students.

Logistic regression was used to estimate exposure odds ratios STET while taking into account multiple risk factors for each site. Several limitations in the study tend to conservatively bias the results. The protocol consisted of randomized exposure of each subject to clean air or 3.

Potential hazardous workplace exposures varied with department and included Mortality from all causes combined was lower than expected for each tannery. Deaths from cancer of each site, including the lung, were also lower than expected compared to those of either the population of the United States or of local state rates.

A significant excess of deaths was observed, however, due to accidental causes in one tannery and cirrhosis of the liver, suicide, and alcoholism in the other. These excesses did not appear to be casually associated with occupational exposures.
