室内甲醛污染影响因素及控制措施研究

Research on Influence Factors and Control Measures of Indoor Formaldehyde Pollution

甲醛已被世界卫生组织确定为可疑致癌和致畸形物质。通过对室内甲醛浓度的连续跟踪监测,分析研究了甲醛在室内引入、扩散和衰减的影响因素。并根据分析结果密度板家具甲醛超标幅度较大,而大芯板、刨花板家具甲醛超标略小;随着装修后入住时间的延长,室内甲醛空气污染水平有不断下降的趋势;提出在装修及选择家具时应优先考虑甲醛含量少的材质及家具,开窗通风可显著降低室内甲醛浓度等控制措施。

Formaldehyde is determined as the suspectable carcinogen and teratogen by World Health Organization.The influence factors for introduction,dispersion and loss of the indoor formaldehyde are analyzed in this paper according to the concentration of indoor formaldehyde which is tracked and monitored continuously.According to the analysis result,the density panel furniture has the larger overproof formaldehyde,and the blockboard and flakeboard has the smaller overproof formaldehyde;the indoor formaldehyde pollution has the continue decreasing trend along with the extending length of residence after decoration;it is proposed that the selection of furniture should consider preferentially the less formaldehyde content material and furniture,and the concentration of indoor formaldehyde can be reduced by ventilation.
