同时室内和室外测量O-3，NO，NO2*（NOx-NO），持续了很多天，发生在两个建筑物，也伴随着其他环境测量。这两座建筑都有明亮的自然阳光，尺寸相似，但在设计和操作方面存在许多差异，通风方式也不同。一个位于塞萨洛尼基（LIDAR），另一个位于雅典（PERPA），这是一个空气污染程度更高的城市。在PERPA大楼，观察到邻近化学实验室的碳氢化合物侵入迹象。这两种建筑之间的差异反映在室内外O-3，NO，NO2* 浓度比的变化行为。在激光雷达大楼。有升高的O-3和NO2* 的比例与小NO的比例相结合。在PERPA-bldg，相应的比例，主要是O-3，长期受到室内VOCs源的影响。对于自然通风和照明的建筑物，O-3浓度比代表了建筑物的设计、操作和位置。也是室内VOCs源存在的敏感指标。24 h室内/室外NO浓度峰值比值反映了建筑物换气速率的差异，但24 h平均NO比值似乎不受任何室内空气质量参数的影响。NO2* 测量包括其他含氮物质的贡献，这似乎是随着建筑物的特性和时间而变化。利用获得的这类室内位置的实验数据，对Nazaroff和卡斯（1986）的数学模型进行了检验，该模型预测了室内空气污染物浓度。模型的结果是令人满意的。此外，有可能对观测到的室内空气污染物浓度的形成原因进行理论研究。室内氮氧化物化学不仅受均相反应的影响，而且受非均相反应的影响，如模型结果所示。(C)1998爱思唯尔科技有限公司。保留所有权利。
Simultaneous indoor and outdoor measurements of O-3, NO, NO2* (NOx-NO) that lasted a lot of days, took place in two buildings and were also accompanied by other environmental measurements. The two buildings have bright natural sunlight, similar dimensions but many differences in their design and operation, as well as a different way of ventilation. The one is located in Thessaloniki (LIDAR) while the other is in Athens (PERPA), a city with a much higher level of air pollution. In the PERPA-bldg., indications of hydrocarbon intrusion from an adjacent chemical laboratory were observed. The differences between these two buildings are reflected in the change of behavior of the indoor/outdoor O-3, NO, NO2* concentration ratios. In the LIDAR-bldg. there were elevated O-3 and NO2* ratios combined with small NO ratios. At the PERPA-bldg, the corresponding ratios, mainly for O-3, were influenced for long period by the indoor VOCs source. The O-3 concentration ratios are representative of the building's design, operation and location in case of naturally ventilated and lighted buildings. Also they are a sensitive indicator of the existence of indoor VOCs source. The 24 h peak indoor/outdoor NO concentration ratios reflected the differences between the buildings' air exchange rate, but the 24 h averaged NO ratios seems unaffected by any indoor air quality parameter in this study. The NO2* measurements include the contribution of other nitrogen-containing species, which seems to vary with the building characteristics and with time. With the acquired experimental data for this type of interior locations, the Nazaroff and Cass (1986) mathematical model was tested, which predicts the indoor air pollutant concentrations. The model's results were satisfactory. In addition, it was possible for the theoretical investigation into the causes of the formation of the observed indoor air pollutant concentrations to be undertaken. The indoor NOx chemistry is not affected only by homogeneous but also by heterogeneous reactions, as shown by model results. (C) 1998 Elsevier Science Ltd. All rights reserved.
