Formaldehyde is a colorless, pungent odor gas that is readily soluble in water, alcohols, and ethers. Formaldehyde has a wide range of uses in industry. It is commonly used in textiles, dyes, leather, resins, paints, plastics, rubber, pharmaceuticals, explosives, and the like. The formaldehyde pollution thus originates mainly from the above products. The harm of formaldehyde to human body is mainly shown in the following aspects: formaldehyde can bind to proteins in the plasma of somatic cells, altering the internal structure of the protein and clotting, thereby rendering it biocidal. The eye mucous membrane is firstly stimulated at low concentration, the upper respiratory tract is stimulated at high concentration, cough and chest distress are caused, meanwhile, the neck has oppression feeling, the mucous membrane is ulcerated, and further inflammation is caused in the lung. After formaldehyde is inhaled, anorexia, weight loss, asthenia and insomnia can be caused; this can lead to hypersensitivity if contacted frequently and can result in ulceration of the skin tissue. Formaldehyde has an anesthetic effect on the central nervous system, and particularly has a strong poisoning effect on eyesight. In addition, formaldehyde can damage intracellular genetic material and is a suspected carcinogen. The long-term exposure to formaldehyde gas can cause headache, weakness, irregular perspiration, temperature change, accelerated pulse, rash, eczema, red swelling and the like.
