甲醛蒸气暴露发生在一个主要的医学院的大体解剖实验室在12周的研究期间进行了检查。使用个人取样泵通过小型撞击器抽取空气，收集甲醛样品，撞击器含有溶解在去离子水中的0.1%亚硫酸氢钠溶液作为吸收介质。从8个实验室轮流收集和分析呼吸区和环境空气样本。通过国家职业安全与健康研究所[美国]推荐的变色酸法进行分析。结果发现，44%的呼吸区样品的职业暴露上限值> 1.0ppm，这是美国政府工业卫生学家会议最近推荐的。只有11%的环境空气样本> 1.0 ppm。
Formaldehyde vapor exposures that occurred in the gross anatomy laboratories of a major medical school during a 12 wk study period were examined. Formaldehyde samples were collected using personal sampling pumps to draw air through midget impingers containing a 0.1% solution of sodium bisulfite dissolved in deionized water as the absorbing medium. Breathing zone and ambient air samples were collected and analyzed from 8 laboratories on a rotating basis. Analysis was via the chromotropic acid method recommended by the National Institute for Occupational Safety and Health [USA]. It was found that 44% of all breathing zone samples were > 1.0 ppm ceiling value for occupational exposure recently recommended by the American Conference of Governmental Industrial Hygienists. Only 11% of ambient air samples were > 1.0 ppm.
