纸基材料降解过程中会产生挥发性醛类。这可能会导致它们在档案和图书馆存储库中积累。但目前尚未进行系统研究。在本研究的框架中，在四个图书馆和档案馆的十个地点进行了被动采样。尽管采样地点差异很大，但没有发现重大差异，尽管空气过滤储存库的挥发性醛（甲醛、乙醛、糠醛和己醛）浓度较低，而不通风的报纸储存库的挥发性醛（甲醛、乙醛、糠醛和己醛）浓度最高。还为一家机构的五名员工提供了个人被动采样器，以调查员工接触挥发性醛的情况。所有值均低于目前有效的暴露限值。挥发性醛、乙酸和挥发性有机化合物 (VOC) 的总体浓度也与室外产生的污染物的浓度进行了比较。很明显，在储存库内，特别是在档案箱内，挥发性有机化合物和乙酸的浓度远高于室外产生的污染物的浓度，而室外产生的污染物的浓度通常与遗产材料相关。这表明有必要进一步研究挥发性有机化合物对遗产材料的促进降解作用，并且应该更加广泛地监测遗产机构中的挥发性有机化合物。 (C) 2010 Elsevier Ltd. 保留所有权利。
Volatile aldehydes are produced during degradation of paper-based materials. This may result in their accumulation in archival and library repositories. However, no systematic study has been performed so far. In the frame of this study, passive sampling was carried out at ten locations in four libraries and archives. Despite the very variable sampling locations, no major differences were found, although air-filtered repositories were found to have lower concentrations while a non-ventilated newspaper repository exhibited the highest concentrations of volatile aldehydes (formaldehyde, acetaldehyde, furfural and hexanal). Five employees in one institution were also provided with personal passive samplers to investigate employees' exposure to volatile aldehydes. All values were lower than the presently valid exposure limits.The concentration of volatile aldehydes, acetic acid, and volatile organic compounds (VOCs) in general was also compared with that of outdoor-generated pollutants. It was evident that inside the repository and particularly inside archival boxes, the concentration of VOCs and acetic acid was much higher than the concentration of outdoor-generated pollutants, which are otherwise more routinely studied in connection with heritage materials. This indicates that further work on the pro-degradative effect of VOCs on heritage materials is necessary and that monitoring of VOCs in heritage institutions should become more widespread.
