甲醛(HCHO)是一种具有强烈刺激性气味的无色气体。易溶于水、醇和醚,能参与多种化学反应。在建筑材料、纺织、绝缘材料和塑料工业中以及医药卫生等方面有广泛的应用。据称有一大批职业人群暴露于浓度在1ppm以上的甲醛气体中,急慢性甲醛中毒病例时有报道,甲醛还具有致敏、致突和致畸效应,近年报道甲醛慢性吸入可以诱发大鼠、小鼠鼻癌,这更加引起人们对甲醛毒性问题的高度重视。 Formaldehyde (HCHO) is a colorless, intensely irritating odor. Soluble in water, alcohol and ether, can participate in a variety of chemical reactions. In building materials, textiles, insulation materials and plastics industry as well as medical and health has a wide range of applications. A large number of occupational groups are said to be exposed to formaldehyde gas concentrations above 1ppm. Cases of acute and chronic formaldehyde poisoning have been reported. Formaldehyde also has sensitization, teratogenicity and teratogenic effects. In recent years, it has been reported that chronic inhalation of formaldehyde can induce rats, small Rat nasal cancer, which is even more caused by the high degree of attention to the toxicity of formaldehyde.
