“…This difference in O 3 annual mean is attributable to the balance between precursors (i.e., volatile organic compounds) and the prevalent NOx in urban areas that scavenges O 3 [74,75]. Moreover, deciduous species generally perform better than evergreen species in O 3 removal due to their higher stomatal conductance [24,76].…”

This study is the follow up of the URBAN-MAES pilot implemented in the framework of the EnRoute project. The study aims at mapping and assessing the process of particulate matter (PM 10 ) and tropospheric ozone (O 3 ) removal by various forest and shrub ecosystems. Different policy levels and environmental contexts were considered, namely the Metropolitan city of Rome and, at a wider level, the Latium region. The approach involves characterization of the main land cover and ecosystems using Sentinel-2 images, enabling a detailed assessment of Ecosystem Service (ES), and monetary valuation based on externality values. The results showed spatial variations in the pattern of PM 10 and O 3 removal inside the Municipality and in the more rural Latium hinterland, reflecting the spatial dynamics of the two pollutants. Evergreen species displayed higher PM 10 removal efficiency, whereas deciduous species showed higher O 3 absorption in both rural and urban areas. The overall pollution removal accounted for 5123 and 19,074 Mg of PM 10 and O 3 , respectively, with a relative monetary benefit of 161 and 149 Million Euro for PM 10 and O 3 , respectively. Our results provide spatially explicit evidence that may assist policymakers in land-oriented decisions towards improving Green Infrastructure and maximizing ES provision at different governance levels.

“…Further studies of O 3 exposure under controlled or semi-controlled conditions involving many urban trees are still needed in order to support decision making for tree plantation in ozone polluted cities of China. Other additional factors to be considered in urban greening species in relation to air pollution are their rate of BVOC emission and their capacity to remove O 3 and particulate matter (Paoletti et al, 2009;Calfapietra et al, 2013).…”

a b s t r a c tFast urbanization has led to ozone (O 3 ) being the main pollutant in summer in most of China. To assess future ground-level O 3 effects on the service of urban greening species and clarify the underlying mechanism of O 3 damage, four common urban greening species, Ailanthus altissima (AA), Fraxinus chinensis (FC), Platanus orientalis (PO) and Robinia pseudoacacia (RP) were exposed to non-filtered air (NF) and to elevated O 3 (E-O 3 ) in open-top chambers. E-O 3 induced visible injury in all species as well as microscopic alterations such as collapse of the palisade parenchyma cells, callose accumulation, or chloroplast and mitochondrial accelerated senescence. E-O 3 significantly reduced light-saturated CO 2 assimilation (A sat ), the maximum activity of Rubisco (Vc max ), the maximum electron transport rate (J max ), and fluorescence parameters such as the quantum yield of noncyclic electron transport ( PSII ), and the quenching of photochemical efficiency of PSII (qP). It also increased total antioxidant capacity, phenolics and ascorbate contents. No significant interaction between O 3 and species was found in photosynthetic performance and antioxidant systems, suggesting that the four species selected were sensitive to O 3 . Of all four species, AA was the most sensitive species due to a combination of earlier injury onset, anatomical features, lower antioxidant responses and higher stomatal conductance. The sensitivity of tree species to O 3 is a factor to be considered for urban greening. Ozone may affect important urban forest ecosystem services by reducing CO 2 assimilation.

“…There is much debate as to the influence of biogenic VOCs in urban (Calfapietra et al, 2013), regional and global ozone budgets. Variation in natural plant emissions of ozone precursors can influence ozone concentrations.…”

Tropospheric ozone and its precursors from the urban to the global scale from air quality to short-lived climate forcer

Abstract. Ozone holds a certain fascination in atmospheric science. It is ubiquitous in the atmosphere, central to tropospheric oxidation chemistry, yet harmful to human and ecosystem health as well as being an important greenhouse gas. It is not emitted into the atmosphere but is a byproduct of the very oxidation chemistry it largely initiates. Much effort is focused on the reduction of surface levels of ozone owing to its health and vegetation impacts, but recent efforts to achieve reductions in exposure at a country scale have proved difficult to achieve owing to increases in background ozone at the zonal hemispheric scale. There is also a growing realisation that the role of ozone as a short-lived climate pollutant could be important in integrated air quality climate change mitigation. This review examines current understanding of the processes regulating tropospheric ozone at global to local scales from both measurements and models. It takes the view that knowledge across the scales is important for dealing with air quality and climate change in a synergistic manner. The review shows that there remain a number of clear challenges for ozone such as explaining surface trends, incorporating new chemical understanding, ozone-climate coupling, and a better assessment of impacts. There is a clear and present need to treat ozone across the range of scales, a transboundary issue, but with an emphasis on the hemispheric scales. New observational opportunities are offered both by satellites and small sensors that bridge the scales.
