摘要
甲醛是室内环境的主要污染物。采用乙酰丙酮分光光度测定方法,通过对一幢五层新建的办公楼随机抽取六间房,每隔3个月分别进行了检测,结果表明室内温度变化对甲醛的释放有较大影响,甲醛的释放随时间逐渐减少。列举了脲醛树脂、酚酞树脂、胺基甲醛树脂等是造成室内甲醛污染的主要来源,甲醛对人体的危害极大,不同国际组织、国家对室内甲醛浓度制定了不同的最高限值。从控制污染源、控制室内条件、处理方法等方面将有效防治室内甲醛污染。
Formaldehyde is a main pollutant in indoor environment.By acethlacetone spectrophotometric method,detection was carried out separately to six random sampled rooms of a five-story new office building every three months.The results show that the change of indoor temperature has a greater influence on the release of formaldehyde,and as days go by,the release tends to reduce gradually until it is roughly stable.Urea-formaldehyde,resin,phenolphthalein resin and amine formaldehyde resin are listed as the main sources causing the indoor formaldehyde pollution.As it is very harmful to the body,international organizations and countries have set the various maximum limits to indoor formaldehyde.However,control of pollution source,indoor condition and treatment process will be effective in combating against indoor formaldehyde pollution.
