摘要
摘 要 甲醛是一項普遍存在的室內空氣污染物，由於具眼鼻黏膜 及上呼吸道刺激性與疑似致癌特性而引起關切。室內甲醛的來源主要來自 含甲醛樹脂的各種合板產品(pressed-wood products)及裝潢建材。國內 房屋整修裝潢頻繁，大量使用合板裝潢及製造陳列櫃、壁櫥，又未限制合 板甲醛釋出量，故可能累積較高濃度之甲醛。本研究企圖揭露此一問題的 重要性並尋求改善之道。本研究涵蓋三部分:(一)問卷調查-以大台北地區 一般民眾為對象進行電話訪問，以了解民眾對合板甲醛釋出的認知與感受 性；(二)比較國內市售合板與國外進口低游離甲醛合板間之甲醛釋出量及 其衰減曲線；(三)測試坊間數種所謂去除合板甲醛偏方的去除效率。問卷 結果顯示，雖然超過半數的民眾(62.1%)對甲醛氣味有感受性，但卻不知 其原因及危害，顯示有關單位應加強對大眾的教育與宣導；合板甲醛釋出 量衰減試驗則顯示『低游離甲醛合板』所散發出的甲醛遠低於一般合板( 十分之一或更低)，國內應儘速訂定室內合板甲醛釋出量標準；至於甲醛 去除效率的研究則指出，市售芳香脫臭劑能有效降低游離甲醛之濃度(降 低22%)，使用茶葉渣(降低27%)或保持良好的室內換氣率(降低25%)亦能去 除甲醛的刺鼻味並有效降低游離甲醛之濃度。

Formaldehyde is an ubiquitous indoor air pollutant. It has been well documented that formaldehyde is an irritant of mucous membrane of eyes, nose, throat, and respiratory tract. It has also been considered as a suspected carcinogen for human by IARC. Most important sources of indoorformaldehyde vapor is emitted from the adhesive used in the pressed-wood products including plywood, particleboard, and paneling. In Taiwan, large quantities of pressed-wood products were used in cabinets, furnitureand the booming interior construction business. The combined effect of tightened buildings and the increased usage of these composite buildingmaterials led to a large increase in the number of high level indoorformaldehyde vapor, It warrant our paying special attention to understandand ameliorate this problem. This study was designed including three parts: (1) administratedtelephone questionnaire to investigate the recognition and attitudes of subjects about formaldehyde emission from pressed-wood products, (2)compared the formaldehyde emission decay curve between domestic and imported pressed-wood products, (3) compared the formaldehyde removing efficiency between several substances which was known to be used to reducethe odor emitted from formaldehyde. The results from the questionnaire shown that high proportion (62.1%) of subjects complaint with pungent-smelling and uncomfortable, while theydid not know the target source. From our decay test, less formaldehyde wasdetected from imported "low emission formaldehyde pressed-wood " products than domestic products (less than 10%) . In addition, comparing the efficiencies of several known methods, the results indicate that "commercialabsorber" could be a good materials to decrease formaldehyde concentration(reduce 22%). The similar function was also be found with tea leafs (reduce27%) and maintaining a good indoor ventilation (reduce 25%). It is recommended that the authorities should contribute more information on formaldehyde for people. In addition, the formaldehyde emission standard on pressed-wood products also should be set. Further,information on "low emission formaldehyde pressed-wood " also should be introduced to suppliers and consumers in our country.
