为了解农村室内不同装潢条件下空气中甲醛及其它有机物的污染现状，探讨其污染来源，对吉林省白城市郊四种装潢类型的７２间居室空气中甲醛浓度和化学耗氧量进行了测定，并对门窗开、闭时的浓度进行对比分析。结果发现：农村居室广泛使用化纤物质进行装潢；室内甲醛测定值均高于无装潢的对照点；无论门窗开、闭，两者差异均有显著性（Ｐ＜０．０１），但其结果未超过我国公共场所卫生标准（０．１２ｍｇ／ｍ３）和世界卫生组织（ＷＨＯ）的空气中甲醛卫生标准（０．０６ｍｇ／ｍ３）；装饰室内空气化学耗氧量低于对照室，可能与外环境中的有机污染源有关。
In order to understand the status of formaldehyde and other organic pollutants in the air under different decorating conditions in rural areas, and to explore the sources of pollution, the formaldehyde concentration and chemical oxygen demand of 72 indoor air samples from four decorating types in the suburbs of Baicheng, Jilin Province were measured. Doors and windows open, closed when the concentration of comparative analysis. The results showed that the chemical fiber material was widely used in rural houses for decoration. The measured values of formaldehyde in indoor were higher than that of non-decorated control points. The difference between open and closed doors and windows was significant (P <0.01) More than the health standards in public places in China (0.12mg / m3) and the World Health Organization (WHO) air formaldehyde health standards (0.06mg / m3); decorative indoor air chemical oxygen consumption is lower than the control room, In the organic sources of pollution.
