甲醛中毒的迹象的严重程度取决于由一个人吸入或摄入的甲醛的量,应该怎样做才能把它在最早的甲醛中毒症状的正确识别。甲醛（化学分子式HCHO，分子量：30.03,是一种无色，有强烈刺激性气味的气体 。易溶于水、醇醚。 在常温下是气态，通常以水溶液和气态形式出现。急性甲醛中毒为接触高浓度甲醛蒸气引起的以眼、呼吸系统损害为主的全身性疾病。
The severity of formaldehyde poisoning depends on the amount of formaldehyde inhaled or ingested by a person. What should be done to correctly identify the earliest symptoms of formaldehyde poisoning. Formaldehyde (chemical molecular formula HCHO, molecular weight: 30.03, is a colorless gas with strong irritant odor. Soluble in water and alcohol ether. It is gaseous at room temperature, usually in the form of aqueous solution and gas. Acute formaldehyde poisoning is a systemic disease caused by exposure to high concentration formaldehyde vapor, which mainly damages the eye and respiratory system.
