由于气候原因和二氧化硫浓度降低，地面臭氧(O-3)是南欧的主要空气污染物之一。无论是在农村还是城市，臭氧水平都非常高。在城市里，O-3会影响人类的健康和物质。关于材料，最相关的是接触文化遗产建筑的污染物。特别是，列入教科文组织世界遗产名录的古迹需要特别监测。在意大利，34%和97%的领土面临的腐蚀风险分别高于石灰石和铜的可容忍水平。在米兰市中心地区，石灰石和铜的腐蚀水平也超过了可容忍的水平。在这一地区，计算了铜的容许O-3浓度。在其他污染物浓度不变的情况下，不能超过这些浓度(范围在30到40微克/立方米(3)之间)，以保持腐蚀水平低于可容忍的水平。(C)2008爱思唯尔有限公司。保留所有权利。
Because of climatic reasons and of reduced concentrations of SO2, ground-level ozone (O-3) is one of the main air pollutants in Southern Europe. Ozone levels are very high both in rural and urban locations. In the cities, O-3 can affect human health and materials. Regarding materials, most relevant is the exposure to pollutants of cultural heritage buildings. In particular, monuments registered on UNESCO's list of the world heritage require special monitoring. In Italy 34% and 97% of the territory is exposed to corrosion risk higher than the tolerable level for limestone and copper, respectively. The tolerable corrosion level for limestone and copper was also exceeded in the central area of Milan. In this area the tolerable O-3 concentration for copper was calculated. These concentrations (ranging between 30 and 40 mu g/m(3)) cannot be exceeded at unchanged concentration of other pollutants to maintain corrosion levels below the tolerable ones.
