在为期八周的学期中，对医学生的大体解剖实验室进行了甲醛水平评估。结果表明，学生和教师的接触低于职业安全和健康管理局规定的3 ppm允许接触限值（假设每天最多接触5小时）。然而，在相同的假设下，大约三分之一的8小时时间加权平均暴露量大于1 ppm。学生和教师的接触水平没有差异。除非解剖尸体内腔，否则暴露量在整个研究期间趋于减少。考虑到甲醛作为动物致癌物的最新含义以及将允许水平降低至1 ppm或更低的趋势，这些暴露是重要的。
A gross anatomy laboratory for medical students was evaluated for formaldehyde levels throughout its eight-week term. Results indicated that exposures for students and instructors were below the 3-ppm permissible exposure limit (assuming a maximum of five hours of daily exposure) established by the Occupational Safety and Health Administration. However, about one third of the eight-hour time-weighted-average exposures were greater than 1 ppm under the same assumptions. Exposure levels for students and instructors did not differ. Exposures tended to decrease over the term unless internal cadaver cavities were being dissected. These exposures are significant in light of the recent implication of formaldehyde as an animal carcinogen and the trend to reduce permissible levels to 1 ppm or lower.
