甲醛(HCHO)是一种无色易溶的刺激性气体,可经呼吸道吸收,其水溶液“福尔马林”可经消化道吸收。现代科学研究表明,甲醛对人体健康有负面影响。长期接触低剂量甲醛可以引起慢性呼吸道疾病、女性月经紊乱、妊娠综合征,引起新生儿体质降低、染色体异常,甚至引起鼻咽癌。高浓度的甲醛对神经系统、免疫系统、肝脏等都有毒害。甲醛还有致畸、致癌作用。据流行病学调查,长期接触甲醛的人,可引起鼻腔、口腔、鼻咽、咽喉、皮肤和消化道的癌症。室内空气中的甲醛来源主要有以下几个方面:1.用作室内装饰的胶合板、细木工板、中密度纤维板和刨花板等人造板材,是形成室内空气中甲醛的主
Formaldehyde (HCHO) is a colorless, easily soluble, irritating gas that is absorbed through the respiratory tract and is absorbed in the aqueous solution “formalin” via the digestive tract. Modern scientific research shows that formaldehyde has a negative impact on human health. Long-term exposure to low doses of formaldehyde can cause chronic respiratory diseases, menstrual disorders, pregnancy syndrome, causing neonatal hypathesis, chromosomal abnormalities and even cause nasopharyngeal carcinoma. High concentrations of formaldehyde on the nervous system, immune system, liver and other toxic. Formaldehyde also teratogenic, carcinogenic effects. According to epidemiological investigations, long-term exposure to formaldehyde can cause cancer of the nose, mouth, nose, throat, skin and digestive tract. Indoor air formaldehyde sources are the following aspects: 1. For interior decoration of plywood, blockboard, MDF and particleboard and other man-made sheet metal, is the formation of indoor air formaldehyde host
