Urban areas are characterized by elevated levels of air pollution and carbon emissions resulting from human activities. Addressing these challenges simultaneously is essential for achieving resilient and healthy cities. Given the potential of urban forests to mitigate both air pollution and carbon emissions, this study focused on quantifying these ecosystem services in Monte Sant'Antonio's urban forest, located in Campobasso, Italy. The urban forest's capacity to remove carbon and atmospheric pollutants (O, SO, NO, CO, and PM) was first assessed using i-Tree Eco v.6 software. The results from i-Tree Eco were then compared with estimates we developed using Italian biomass calculation equations from the 2015 National Inventory of Forests and Carbon Sinks. To support this comparison, linear regression models were developed to characterize the relationships between total tree biomass (independent variable) and pollutant removal and carbon sequestration (dependent variables) by individual tree species. The analysis followed a stepwise approach. Subsequently, we assessed temporal variations in air pollutants removal capacity and gross carbon sequestration for the two tree species present in all four stands analyzed: Fraxinus ornus L. and Pinus nigra J.F. Arnold. Based on the estimates derived from applying the models using total tree biomass calculated with Italian equations, the urban forest of Monte Sant'Antonio can remove approximately 1 ton of pollutants per year (CO, O, NO, SO, PM) and approximately 158 tons of gross carbon sequestration per year.
城市地区的特点是人类活动导致空气污染和碳排放水平升高。同时应对这些挑战对于建设具有韧性和健康的城市至关重要。鉴于城市森林具有减轻空气污染和碳排放的潜力，本研究聚焦于量化位于意大利坎波巴索的圣安东尼奥山城市森林的这些生态系统服务。首先使用i-Tree Eco v.6软件评估了该城市森林去除碳和大气污染物（臭氧、二氧化硫、氮氧化物、一氧化碳和颗粒物）的能力。然后将i-Tree Eco的结果与我们使用2015年国家森林和碳汇清单中的意大利生物量计算方程得出的估计值进行比较。为支持这一比较，开发了线性回归模型来描述总树木生物量（自变量）与单个树种的污染物去除和碳固存（因变量）之间的关系。分析采用逐步方法。随后，我们评估了在所分析的所有四个林分中均存在的两种树种（欧洲白蜡树和黑松）去除空气污染物的能力和总碳固存的时间变化。根据使用意大利方程计算的总树木生物量应用模型得出的估计值，圣安东尼奥山的城市森林每年可去除约1吨污染物（一氧化碳、臭氧、氮氧化物、二氧化硫、颗粒物），每年总碳固存约158吨。
