甲醛是醛类分子中最简单的一种,气态甲醛为无色、具有强烈刺激性气味且氧化性强的挥发性气体。其易溶于水、醚和醇。甲醛作为固定剂,具有价格低廉的优势,现仍为多数实验室首选用品。国际癌症研究机构已将甲醛列为Ⅰ类致癌物~([1])。甲醛的职业接触人群主要为接触甲醛的工人、医务工作者和医学院校的解剖学和病理学等实验技术人员等~([2-4])。这些实验技术人员在标本制作、固定、灌注和保存等过程中需长时间接触高水平的甲醛。随着开放性实验室培
Formaldehyde is the simplest type of aldehyde molecules, gaseous formaldehyde is colorless, with strong irritating odor and strong oxidizing volatile gases. It is soluble in water, ether and alcohol. Formaldehyde as a fixative, with the advantages of low prices, is still the preferred choice for most laboratories. The International Agency for Research on Cancer has classified formaldehyde as a type I carcinogen ~ ([1]). Formaldehyde occupational exposure to the crowd mainly for workers exposed to formaldehyde, medical workers and medical institutions such as anatomy and pathology laboratory technicians and so on ~ ([2-4]). These lab technicians need long-term exposure to high levels of formaldehyde during specimen preparation, immobilization, perfusion and preservation. With open lab training
