Ozone levels along urban-to-rural gradients in three Italian cities (Milan, Florence, Bari) showed that average AOT40 values at rural and suburban sites were 2.6 times higher than those determined at urban sites. However, O(3) also exceeded the European criteria to protect forest health at urban sites, even when the standards for human health protection were met. For protecting street trees in Mediterranean cities, the objectives of measurement at urban sites should extend from the protection of human health to the protection of vegetation as well. A review of forest effects on O(3) pollution and of O(3) pollution on forest conditions in Italian cities showed that it was not possible to distinguish the effect of O(3) in the complex mixture of urban pollutants and stressors. A preliminary list of tree species for urban planning in the Mediterranean area shows the average tree capacity of O(3) removal and VOC emission.
意大利三个城市（米兰、佛罗伦萨、巴里）沿城市到农村梯度的臭氧水平表明，农村和郊区站点的平均累积臭氧暴露量（AOT40）值比城市站点测定的值高2.6倍。然而，即使满足了人类健康保护标准，城市站点的臭氧（O₃）仍超过了保护森林健康的欧洲标准。为保护地中海城市的行道树，城市站点的测量目标应从保护人类健康扩展到保护植被。对意大利城市森林对臭氧污染的影响以及臭氧污染对森林状况的综述表明，在城市污染物和压力源的复杂混合物中，无法区分臭氧的影响。地中海地区城市规划的初步树种清单显示了树木去除臭氧和挥发性有机化合物排放的平均能力。
