Denelspment of the method for evaluating melti vols lemels and deciding measurement in meurly-baiet office rooms.

测定了部分办公大楼室内空气和办公大楼附近室外空气中甲醛和挥发性有机化合物（VOCs）的浓度。比较了几种室内和室外空气中甲醛和挥发性有机化合物的测定方法。本文通过对新建办公楼烤制过程中甲醛和挥发性有机化合物（VOCs）的时间序列测定，作为对新建办公楼甲醛和挥发性有机化合物（VOCs）的对抗措施。我们得到的结果如下。我们得到的结果如下。市区总挥发性有机化合物和甲醛含量分别约为10 μg/m^3和10 μg/m^3左右。市区总挥发性有机化合物和甲醛浓度分别约为100 μg/m^3和10 μg/m^3。新建办公楼的总挥发性有机化合物和甲醛含量分别在100 ~ 1000 μg/m^3和10 μg/m^3左右。普通办公楼的总voc和甲醛含量分别为100 μg/m^3和10 μg/m^3。室内总挥发性有机化合物和甲醛含量高于室外，因为挥发性有机化合物和甲醛被认为是从室内蒸发的。作为降低新建办公楼办公室总挥发性有机化合物和甲醛含量的对策措施，烘培处理在某些情况下被证实是有效的。然而，在某些情况下，烘焙治疗的效果并不完美。因此，通过打开窗户或维持通风系统来通风是必要的。本文研制了一种小型连续测量挥发性有机化合物（VOCs）的设备，并与Tenax管吸附-热解吸- gc /MS分析方法进行了比较。我们验证了两种方法之间的正相关关系，考虑到两种方法的水平差异以及两种方法之间的相关性，该设备可以用于新建办公楼和住宅中空气中挥发性有机化合物的测量。需要在不同地点使用这两种方法的进一步数据来调整该设备以测量许多工作场所的挥发性有机化合物水平。到目前为止，我们还没有确定产生“多化学敏感性”或“病态建筑或病态房屋综合症”的实际关键原因，这些通常被认为是与voc或甲醛接触有关。这一点需要进一步研究。少

We measured the concentrations of formaldehyde and volatile organic compounds (VOCs) in indoor air of some office buildings and in the outdoor air near the buildings. We compared some methods of measuring formaldehyde and VOCs in some indoor and outdoor air. We measured time series of formaldehyde and VOCs in newly-built office buildings during bake-out performed as coutermeasurement to formaldehyde and VOCs in the buildings. Our results obtained were as follows.Our results obtained were as follows.The total VOCs and formaldehyde levels in suburbs arca were about several 10 μg/m^3 and approximately 10 μg/m^3. The total VOCs and formaldehyde levels in urban area were about several 100 μg/m^3 and approxmmately 10 μg/m^3. The total VOCs and formaldehyde levels in newly-built office buildings were about several 100 μg/m^3-several 1,000 μg/m^3 and approximately 10 μg/m^3. The total V0Csand formaldehyde levels in ordinal office buildings were about several 100 μg/m^3 and several 10 μg/m^3. T … More he indoor total VOCs and formaldehyde levels were higher than the outdoor ones because VOCs and formaldehyde assumed to be evaporated from interior.Bake-out treatment, being performed as countermeasurement to reduce total VOCs and formaldehyde levels in the offices of newly-built buildings, was verified effective in some cases. However the effectiveness of the bake-out treatment was not perfect in some cases. So ventirating a room by opening the windows or maintaining ventiration system were needed.A continuous measuring small equipment for VOCs has been developed recently We compared this equipment with the another method, absorbed on Tenax tube-desorbed by thermal desorption equipment-GC/MS analysis method. We verified the positive correlation between the two methods This equipment can be used to measure airborne VOCs in newly-built office buildings and houses when considering the difference between the levels of both methods and the correlation between the both methods. Further data using both methods in different places are needed to adapt this equipment for measuring VOCs level in many workplaces.So far, we have not identified the actual critical reason that generates " multi chemical sensitivity " or " sick built or sick house syndrome ", which are offen considered to occurs with exposure to VOCs or formaldehyde. Further studies are needed for this point. Less
