摘要
本文研究了北京远郊顺义县农村不同类型住宅室内甲醛的污染来源、浓度分布以及与住宅平面布置的关系。研究发现,各类住宅室内甲醛浓度超过0.05mg/m^3的样品占0～25％,超过0.08mg/m^3的样品占0～12.5％,超过0.1mg/m^3的占0～8.3％。平均浓度虽均未超过0.05mg/m^3,但新式住宅相对高于旧式住宅,而且前者的主室甲醛浓度高于厨房,最高值可达0.249mg/m^3,主要污染源是室内胶合板家具和装饰物品。旧住宅厨房甲醛高于主室,最高值可达0.407mg/m^3,主要污染源是燃料燃烧。研究中发现,北方农村住宅的设计已不适应随着农民居住水平的提高而出现的新的卫生问题,急待研究设计出既能保暖又有利于通风换气的新的住宅类型。并提出制订室内空气质量卫生标准的必要性。
In 1588 samples of 4 types houses,HC-HO level in the A-bedrooms was highest.The average concentration was 0.407mg/m3.The highest concentration was 0.249mg/m3.HCHO level in summer was higher than that in winter.The main pollution resources was new furnitrue and modern decorating materials.HCHO in D-kitchens was the highest among all kitchens in 4 types houses.The highest concentration was 0.407mg/m3.But the average concentration of D-kitchens was lower than that of A-bedrooms.HCHO level in winter was higher than that in summer.The main pollution resource was fuel-burning(wood,coal & LPG).Not only in old houses but also in new houses there,the air flow rate of those rooms was very low so that ihe indoor pollutants were hardly to exhaust outside.It is very important to design a new house type to improve the ventilation.
