【摘要】：目的了解武汉市新装修居室空气中甲醛的污染情况及其动态变化规律和室内装修装饰材料的构成。方法于2005年4月,选择武汉市新装修的66户住户,连续6个月监测室内空气中的甲醛浓度,同时对室内装饰材料的构成做相关调查。结果武汉市新装修居室空气中甲醛浓度在第4次监测(7月)时达到峰值,其平均浓度为0.272mg/m3,超过国家卫生标准(0.1mg/m3)1.72倍,此后甲醛浓度随时间的延长而逐渐降低。6个月后,仍有近30%的住户室内空气甲醛浓度超标。人造板材占家具和门窗、墙面等装修材料构成的81.48%,成为室内空气甲醛污染的主要来源。结论新装修居室空气中甲醛浓度的降低是一个长期缓慢的过程。大量使用易挥发甲醛的装饰材料(人造板材)造成新装修居室空气中甲醛污染严重。
[Abstract]:Objective to understand the pollution of formaldehyde in the air of newly decorated rooms in Wuhan and its dynamic changes and the composition of decoration materials. Methods in April 2005 66 newly decorated households in Wuhan were selected to monitor the formaldehyde concentration in indoor air for 6 months and the composition of interior decoration materials was investigated. Results the concentration of formaldehyde in the air of newly decorated rooms in Wuhan reached its peak at the fourth time of monitoring (July). The average concentration of formaldehyde was 0.272 mg / m ~ 3, which was 1.72 times higher than the National Health Standard (0.1mg/m3). After 6 months, nearly 30% of the indoor air formaldehyde concentration exceeded the standard. Artificial panels account for 81.48% of furniture, doors and windows, walls and other decoration materials, become the main source of indoor air formaldehyde pollution. Conclusion the decrease of formaldehyde concentration in the air of newly decorated rooms is a long and slow process. A large number of volatile formaldehyde decorative materials (artificial panels) caused serious pollution of formaldehyde in the air of newly decorated rooms.
