装修后室内甲醛、苯系物浓度影响因素研究

目的　了解装修后室内甲醛、苯系物污染状况与装修时间、板材使用量、通风等因素之间的关系 ,为装修后科学选择入住时间提供依据。方法　选择装修后 3～ 18周居室进行调查 ,分析调查因素与污染物浓度的关系。结果　室内甲醛浓度与人造板材使用量、通风时间、检测时的温度等因素有明显的相关关系 (P<0 .0 5 ) ,苯系物浓度与装修时间、通风时间等因素有明显的相关关系 (P <0 .0 5 ) ;甲醛、苯系物浓度与楼层、房屋高度等因素无明显的相关关系 (P >0 .0 5 )。结论　室内装修不宜过多使用人造板材。装修后应该保持经常通风。入住时间一般应在装修结束 13周以后。

Study of Influence Factors on Formaldehyde, Benzene series Concentrations in Newly Decorated Room

Objective To find out the association between the indoor formaldehyde, benzene series pollution and the plank material, decoration time, well ventilated etc, and provide scientific basis for choosing suitable time to live after decoration. Methods A survey on the indoor pollution was conducted 3-18 weeks after decorated room. Association between the factors and the pollutant density was analyzed. Results Formaldehyde concentrations was related to the plank material, decoration time and monitoring temperature (P<0.05) and benzene series concentrations was related to the decoration time, well ventilated time etc (P<0.05). But no significant association was observed between formaldehyde and benzene series concentration and height of the building and room (P>0.05). Conclusions To control air pollution of indoors decoration, excessive artificial plank material should not used and ventilation should be kept. The suitable time to live in was 13 weeks after decoration.
