本文介绍了两个环境监测活动的结果，需要分析之前和之后的“翁贝托l”隧道在罗马，意大利的改造工作登记的氮氧化物水平。数据收集的结果突出了通过用水泥基涂料对隧道拱顶进行光催化处理来有效减少污染物，翻新后发现的较低浓度证明了这一点。在隧道中心计算出约20%的NOx减少（作为两个时间段之间的绝对比较），而在相同位置计算出超过50%的NOx减少，考虑到在罗马市官方站登记的参考数据（官方环境署- ARPA）.从统计学角度看，监测活动的持续时间似乎很长，与之前所有的光催化材料实验不同，根据2004/54/EC关于公路隧道安全的指令，该改造项目可以被证明是欧洲隧道可持续升级的广泛计划的一个非常有用的参考。(C)2011爱思唯尔有限公司版权所有。
This paper deals with the results of two environmental monitoring campaigns entailing the analysis of NOx levels registered before and after the renovation work of the "Umberto l" tunnel in Rome, Italy. The results of the data collection highlighted an efficient abatement of pollutants by the photocatalytic treatment of the tunnel vault with a cement-based paint, as evidenced through the lower concentrations found after the renovation. A NOx reduction of about 20% was calculated in the center of the tunnel (as an absolute comparison between the two periods), whereas a NOx reduction of over 50% was calculated in the same position, considering the reference data registered in the official stations of the city of Rome (Official Environmental Agency - ARPA).The duration of the monitoring campaigns performed seems to be considered significant from the statistical point of view, unlike all previous experiments which were carried out on the photocatalytic materials.This renovation project can prove out to be a very useful reference for the wide program for a sustainable upgrading of tunnels in Europe, according to the Directive 2004/54/EC on road tunnel safety.
