摘要
2004年,甲醛已被世界癌症组织列为一类致癌物质,国标要求室内空气甲醛的限量值为0.1mg/m^3。文章综述了装修住宅室内空气甲醛污染的危害,并认为室内空气甲醛的主要污染来自于装修用的胶黏剂。分析了全国部分地市甲醛污染的情况,发现各地市都存在不同程度的室内空气甲醛污染,最高超标20.6倍。治理甲醛污染的主要方法有通风换气法、物理吸附法、光催化降解法和生物净化法,但主要还是应该从污染的根源入手。
In2004,formaldehyde,one of the main indoor airborne pollutants,was considered as carcinogen by World Health Organization's cancer research agency.In Chinese standard,formaldehyde concentration of indoor air is less than0.1mg/m3.This paper reviews the harm of indoor air formaldehyde pollution to human beings,and consider that the main pollution source of formaldehyde in indoor air is adhesive,which is widely used in indoor decoration.We analysis the indoor air formaldehyde pollution of some cities,and found that the many cities have been pollution by formaldehyde in varying degree,the maximum value of indoor air formaldehyde pollution can reach more than20.6times than that of the national standard.The main methods for the treatment of indoor formaldehyde pollution are interior ventilation,physically absorbed,photocatalytic degradation and biological purification,but truly harness it needs starting with the management and planning of the source of pollution.
