Objective: To study the effect of formaldehyde on DNA-protein crosslinks (DPC) in buccal cells in students who were taking anatomy course. Methods: The modified KCl-SDS precipitation assay was applied. This method has been used to explore DPC induced by different pollutants in laboratory studies. Results: 37 students in medical school and 40 in school of sciences were studied. The frequency of exposure to formaldehyde was 6 h per week in exposed group. Concentrations of formaldehyde in anatomy laboratory ranged from 0.42 to 1.57 mg/m. Exposure ...
