Formaldehyde has been discussed as a typical indoor pollutant for decades. To evaluate the current state-of-the-art in formaldehyde research and to identify the plethora of regulated and unregulated formaldehyde sources in indoor and outdoor spaces, an extensive literature search was carried out. The acquired data were analyzed with the aid of Monte-Carlo methods to calculate realistic formaldehyde concentration profiles and exposure scenarios under consideration of aging, source/sink behavior and diffusion effects. Average concentrations of formaldehyde are within 20-30 µg/m³ for European households under residential-typical conditions. The assumption of an average air exchange rate of 0.5 h is also plausible. Formaldehyde emission rates of materials and products for indoor use are widely spread and range from non-detectable to > 1000 µg/h. However, processes like combustion, cleaning activities, operation of air purifiers and indoor chemistry were identified as temporary but relevant formaldehyde sources, which might cause high peak concentrations.
几十年来，甲醛一直被视为典型的室内污染物。为了评估甲醛研究的当前技术水平，并确定室内外空间中大量受管制和不受管制的甲醛来源，我们进行了广泛的文献检索。借助蒙特卡洛方法对获取的数据进行分析，以计算在考虑老化、源/汇行为和扩散效应的情况下，实际的甲醛浓度分布和暴露情景。在典型居住条件下，欧洲家庭室内甲醛的平均浓度在20-30微克/立方米之间。假设平均空气交换率为0.5小时也是合理的。室内使用的材料和产品的甲醛排放率差异很大，范围从检测不到到>1000微克/小时。然而，燃烧、清洁活动、空气净化器运行和室内化学反应等过程被确定为临时但相关的甲醛来源，可能会导致高浓度峰值。
