2005年济宁市市中区装修房屋室内空气污染状况调查

Investigation on Indoor Air Pollution in Shizhong District of Ji'ning City in 2005

[目的]了解住宅装修后室内空气污染状况及对居民健康的危害。[方法]根据装修竣工时间、装修组选择2个月以内、2～4月、5～8月、9～11月、12～18月的居室150间,对照组选择装修5年以上的居室50间,对空气中甲醛、氨、VOCs污染物浓度进行测定。并对装修材料进行调查。[结果]居室装修材料以涂料、油漆、地毯、复合地板为主,装修1年内,甲醛、氨、VOCs的浓度分别为13.3%、15.9%、16.6%,均高于对照组,且差异有统计学意义(P<0.05)。在装修后2个月内,甲醛、氨、VOCs的合格率最低,分别为0.00、12.7%、16.1%。影响污染物浓度的主要因素为竣工时间、油漆、涂料、复合地板、地毯、人造板用品。[结论]装修对室内空气造成了污染。随使用时间的延长,甲醛、氨、VOCs的浓度逐渐下降。

[Objective]To explore indoor air pollution after decoration and the danger to the people＇s health. [Methods] According to the completed time,the concentration of formaldehyde,benzene and VOCs was determined in 150 rooms decorated within 2 months,2-4 months,5-8 months and 9-11 months,as well as 50 rooms decorated over 5 year＇s which was selected as control group. The decoration materials in the 2 groups were investigated. [Results]The main materials were coating material, paints, fiber carpet, compound floor board. The concentration of formaldehyde, benzene and VOCs was 13.3 %,1 5.9% and16.6% respectively, and significantly higher than that in control group. There was a difference （ P〈0.05）. The qualified rate of formaldehyde,benzene and VOCs was the lowest in room air after 2 months of decoration,accounting for 0.00,12.7 %and 16.1% respectively. The main causes were completed time, coating material, paints, compound floor board, fiber carpet, artificial floor board. [Conclusion]The concentration of formaldehyde, benzene and VOCs in indoor air caused by decoration decreased along with the duration of decoration.
