甲醛除了在木材、树脂和塑料的生产过程中使用外，还常在解剖实验室中用作防腐剂。本研究使用NIOSH 2541方法测量解剖实验室工作人员和医学生的甲醛暴露水平。本研究采用改良后的症状自评问卷对甲醛暴露引起的症状进行了测定。解剖室和标本制备实验室8 h TWA中甲醛的平均面积浓度分别为0.1±0.03和0.17±0.04 ppm。这两种甲醛浓度均低于0.30 ppm的上限。解剖室与标本制备室甲醛浓度无统计学差异。个人暴露15分钟STEL甲醛浓度为2.30±1.53 ppm，高于15分钟STEL 2 ppm。对解剖实验室工作人员和医学生进行症状自评问卷调查，结果显示，他们在工作时间和下班时间最常见的症状是眼和鼻刺激，分别占71.3%、57.5%和4.6%、8%。总之，个人暴露15分钟STEL超过了美国OSHA标准。尽管该地区的甲醛浓度低于限值，但仍存在对健康产生不利影响的风险。
Formaldehyde has commonly been used as an embalming agent in the anatomy laboratory besides being used during production of wood, resins and plastics. This current study involved the measurement of formaldehyde exposure level among anatomy laboratory workers and medical students in anatomy laboratory using the NIOSH 2541 method. The study determined the symptoms resulted from formaldehyde exposure using self-reported symptom questionnaire that has been modified. Mean area concentration of formaldehyde 8 h TWA in the dissection hall and specimen preparation laboratory were 0.1±0.03 and 0.17±0.04 ppm, respectively. Both of these formaldehyde concentrations were below the ceiling limit of 0.30 ppm. Statistically, there was no significant difference between the formaldehyde concentration in the dissection hall and specimen preparation laboratory. The personal exposure 15 min STEL formaldehyde concentration was 2.30±1.53 ppm and it was higher than 15 min STEL of 2 ppm. Results from the anatomy laboratory workers and medical students reported through the self-reported symptom questionnaires revealed that the most common symptoms they experienced during working hour and off working hour where eye and nose irritations, which are 71.3%, 57.5 and 4.6, 8%, respectively. In conclusion, the personal exposure 15 min STEL exceeded the US OSHA standard. Even though the formaldehyde concentration for the area was under the limit, still there were risks to develop an adverse health effect.
