新装修居室甲醛、总挥发性有机物浓度变化规律分析

通过对乌鲁木齐市新装修居室空气连续6个月的追踪监测,分析新装修居室甲醛、总挥发性有机物浓度的动态变化规律。结果表明,室内甲醛的浓度随装修竣工后时间的增加呈现降低趋势,但到第6个月为止,绝大部分住户室内空气甲醛浓度依然超标。总挥发性有机物的浓度降低趋势较为明显,到第5个月时,绝大部分住户室内空气总挥发性有机物浓度达到国家标准限值的要求。室内空气甲醛浓度的降低是一个长期缓慢的过程,居室内甲醛污染对人体健康的危害应引起人们的足够重视。

Study on the Regularity of Various Concentration of Formaldehyde and Total Volatile Organic Compounds in Newly Decorated Rooms

Through follow-up monitoring air quality in the newly decorated room in Urumqi for 6months,the article analyses the dynamic changes of concentration of formaldehyde and volatile organic compounds.The results showed that indoor formaldehyde concentration had the decrease tendency with the time increase after the completion of decoration,but to the first 6 months,formaldehyde concentration of indoor air among the most households still exceeded standard value.The reduction tendency of the total volatile organic concentration was more obvious,to the first 5 months,volatile organic compounds concentration of indoor air among the most households satisfied the limit requirements of national standards.Reduction of indoor air formaldehyde concentration is a long and slow process,so the hazard of living room formaldehyde pollution to human health should arouse people＇s attention.
