The objective of this investigation was to determine if there was a seasonal effect on formaldehyde emissions from paneling and shelving in a one story office building. Measurement of formaldehyde was done by standard impinger sampling techniques using 1% bisulfate absorbing solution and by using a dry diffusional formaldehyde monitor. Results show a definite seasonal trend for formaldehyde concentrations by either monitoring method. The formaldehyde concentrations for warm weather are about twice as great as those in cold weather. In addition the dry diffusional monitor concentrations determined were consistently low compared to impinger sampling.
本次调查的目的是确定单层办公楼中镶板和搁板释放甲醛是否存在季节性影响。甲醛测量采用标准冲击式采样技术，使用1%硫酸氢盐吸收溶液，并使用干式扩散甲醛监测仪进行。结果表明，无论采用哪种监测方法，甲醛浓度都呈现出明显的季节性趋势。温暖天气下的甲醛浓度约为寒冷天气下的两倍。此外，与冲击式采样相比，干式扩散监测仪测定的浓度始终较低。
