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

我们测量了一些办公楼室内空气中的甲醛和挥发性有机化合物(VOCs)的浓度以及建筑物附近的室外空气中的挥发性有机化合物(VOCs)的浓度。对一些室内外空气中甲醛和VOCs的检测方法进行了比较。对新建写字楼在烘烤过程中甲醛和VOCs的时间序列进行了测量，作为对建筑物中甲醛和VOCs的对比性测量。结果表明：郊区大气中VOCs和甲醛浓度分别为10μg/m^3和10μg/m^3左右，市区VOCs和甲醛浓度分别为100μg/m^3和10μg/m^3左右，新建写字楼中VOCs和甲醛浓度分别为100μg/m^3和10μg/m^3左右，一般写字楼V0C和甲醛浓度分别为100μg/m^3和10μg/m^3左右。室内总VOCs和甲醛水平比室外高，因为VOCs和甲醛是从室内蒸发出来的。烘烤处理作为降低新建建筑办公室总VOCs和甲醛水平的对策措施，在某些情况下被证明是有效的。然而，烘烤疗法的效果在某些情况下并不完美。因此需要打开窗户进行通风或维护通风系统。我们最近研制了一种VOCs的连续测量小型设备，并将该设备与另一种热解吸管吸附的方法-GC/MS分析方法进行了比较。验证了两种方法之间的正相关性，考虑到两种方法水平的差异以及两种方法的相关性，该装置可用于新建写字楼和住宅的空气中VOCs的测量。需要在不同地方使用这两种方法的更多数据，以使该设备适用于许多工作场所的VOCs水平测量。到目前为止，我们还没有确定产生“多种化学敏感性”或“病房综合症”的实际关键原因，这通常被认为是与VOCs或甲醛接触发生的。关于这一点，还需要进一步的研究。较少
