甲醛是一种无色,有强烈刺激性气味的气体,易溶于水和醇、醚等有机溶剂。近年来,其已成为危害最严重的室内空气污染物之一[1-2]。在工业生产中,甲醛是树脂、橡胶和塑料等合成工业的重要化工原料及许多化工产品的中间产物,因此,其职业接触十分广泛。研究表明,短时间接触高水平的甲醛可致急性损害,主要表现为对皮肤、眼睛和上呼吸道黏膜等的刺激作用,甚至可引起急性肺损伤;长时间低水平接触甲醛可对机体内分泌系统、神经系统、生殖系统、血
Formaldehyde is a colorless, intensely irritating gas that is readily soluble in water and in organic solvents such as alcohols and ethers. In recent years, it has become one of the most harmful indoor air pollutants [1-2]. In industrial production, formaldehyde is an important chemical raw material of synthetic industry such as resin, rubber and plastic, and an intermediate product of many chemical products. Therefore, its occupational exposure is very extensive. Studies have shown that short-term exposure to high levels of formaldehyde can cause acute damage, mainly manifested as stimulation of the skin, eyes and upper respiratory tract mucosa, and even cause acute lung injury; prolonged exposure to low levels of formaldehyde on the body’s endocrine system, Nervous system, reproductive system, blood
