背景與目的
甲醛為最常見的室內空氣汙染毒物,建築物、傢俱以及夾板等相關產品均含有甲醛,其濃度易受到環境中之溫濕度影響。因此本實驗控制相對濕度在低相對濕度(40±5)%、高相對濕度(80±5)%,測量七層合板、木心板、塑合板之甲醛逸散濃度及逸散速率,以及比較在相同相對濕度之情況下,不同合板之甲醛逸散濃度及逸散速率。
方法
本研究分析七層合板、木心板、塑合板等三種合板之甲醛逸散情形,利用方法CLA2404進行採樣,使用採樣介質2,4-DNPH之採樣管以流量115 mL/min之幫浦採集甲醛,樣本以HPLC/UV分析。暴露箱環境條件設定為相對濕度(40±5)%及相對濕度(80±5)%,每種合板於2個相對濕度皆各採樣8次,共採集了48個樣本。使用無母數分析Mann-Whitney U以及Kruskai-Wallis H進行統計分析。
結果
甲醛逸散速率最高值出現在塑合板於高相對濕度之環境條件下,其平均值及標準差為4013±1202.71 μg/m2h,而最小值則是在七層合板於低相對濕度之環境條件,其甲醛逸散速率平均值及標準差為779±96.55 μg/m2h。在固定相對濕度的情況下,三種合板之間的差異在統計學上具有顯著意義。而在同種合板於不同相對濕度作比較,三種合板在高、低相對濕度之差異皆在統計學上具有顯著意義。
結論
三種合板不論高、低相對濕度之甲醛逸散量皆超過台灣低逸散健康綠建材所訂定之標準須小於0.08 mg/m2h;且因甲醛屬於水溶性之化學物質在台灣高相對濕度之環境下,增加了甲醛的溶出使環境中甲醛濃度升高。

Introduction
Plywood production processes use glue containing formaldehyde. The aims of this study are to assess the formaldehyde emission rate from chipboard, block board and seven-layer plywood in an exposure chamber with controlled relative humidity and to evaluate the effect of relative humidity in the formaldehyde emissions of the three types of plywood.
Method
The relative humidity (RH) of the exposure chamber was set at (40.44±1.86)% and (77.74±0.35)% at the constant room temperature to represent the high and low humidity conditions respectively. The sampling protocols followed the CLA 2404 method with the 2,4-DNPH tube as the sampling medium. All samples were quantified by HPLC/UV. The emissions of each types of the plywood were measured eight times at two different relative humidity conditions. The amounts of 48 emission samples were collected. All data were analyzed by Mann-Whitney and Kruskai-Wallis H tests. The statistical significance level was set at p<0.05.
Result
The maximum formaldehyde emission rate was detected from the chipboard, 4013±1202.7 µg/m2-h, under high RH condition. The minimum formaldehyde emission rate was from the seven-layer plywood, 779±96.55µg/m2-h, with low RH condition. The formaldehyde emission rates of these three plywood were significantly different ( p<0.001) and the RH did affect the formaldehyde emission rate significantly ( p<0.001).

Conclusion
This research found that the formaldehyde emission rates from the tested plywood all exceeded the low emission criteria of Healthy Building Material in Taiwan, < 0.08 mg/m2-hr. The humid environment made the formaldehyde emission worse.
