“…ATMOSPHERIC IMPLICATION Currently, levels of O 3 and NH 3 in the atmosphere have been increasing over many regions of the earth. 135,136 Though anthropogenic emissions of SO 2 and NO 2 have declined, their concentrations can still be above 100 ppb during severe haze pollution episodes. 137,138 Anthropogenic−biogenic interactions occurring between β-pinene and these pollutants have been systematically investigated in the present study for the first time.…”

The oxidative photo-dehydrogenation of glycerol to produce H2 and other valuable chemicals was studied using different materials. In particular, Pt nanoparticles were deposited on microemulsion-synthesized TiO2 via surface organometallic chemistry (SOMC) and compared with photocatalysts obtained using more conventional methods. Welldefined Pt(II) single-site titania-grafted were prepared reacting the surface hydroxyl groups of TiO2 nano-oxides with the organometallic Pt(COD)Me2 complex. Sample reduction under H2 generated ultrafine Pt nanoparticles well-dispersed on titania surface. Its performance under simulated solar light showed superior activity when compared to analogous Ptcontaining catalysts prepared by other methods. Improved dispersion of Pt metal on titania surface was among the primary reasons of a better overall activity, providing relatively high rates of hydrogen productivity. Moreover, an increase of glyceraldehyde productivity in liquid phase was observed with the increase of Pt dispersion, demonstrating that the metal dispersion can strongly affect the selectivity of chemicals produced in the reaction. Comparison with state of the art shows that the present material exhibits excellent performance for a combined positive effect of the high specific surface area of titania prepared by microemulsion, giving access to the increased densities of active sites and the high dispersion of Pt nanoparticles given by the SOMC technique.

“…The first comprehensive review [3] covered the fundamental chemical and meteorological processes involved in O 3 production and transport, the history of O 3 monitoring and research in China, the O 3 concentrations in major city-clusters, the relationships between O 3 concentrations and their precursors, early findings on the roles of nitrous acid (HONO) and nitryl chloride (ClNO 2 ) in O 3 production, and the impacts of O 3 on crops, forests and human health. Subsequently, five additional topical reviews were published [7][8][9][10][11]. Lu et al [7] reviewed findings on the O 3 formation regimes and their temporal (inter-annual, seasonal and diurnal) changes for period up to 2016.…”

“…Liu et al [10] reviewed the methodological aspects of O 3 and precursor apportionment, including back trajectories, observationbased chemical models, receptor models for volatile organic compounds (VOCs), emission-based chemical transport model, and their respective results. Xu [11] provided a short review of the impacts of O 3 on crop yield and economic loss, tree risk exposure to O 3 , and cardio-vascular mortality with O 3 exposure dose. The O 3 spatial distribution and changes across China from 2013 up to 2019 were presented in three of the above reviews [9][10][11], and the decadal trends of O 3 at limited number of sites were reviewed in two of them [9,11].…”

Ozone (O3) in the troposphere is an air pollutant and a greenhouse gas. In mainland China, after the Air Pollution Prevention and Action Plan was implemented in 2013 – and despite substantial decreases in the concentrations of other air pollutants – ambient O3 concentrations paradoxically increased in many urban areas. The worsening urban O3 pollution has fuelled numerous studies in recent years, which have enriched knowledge about O3-related processes and their impacts. In this article, we synthesise the key findings of over 500 articles on O3 over mainland China that were published in the past six years in English-language journals. We focus on recent changes in O3 concentrations, their meteorological and chemical drivers, complex O3 responses to the drastic decrease in human activities during coronavirus disease 2019 lockdowns, several emerging chemical processes, impacts on crops and trees, and the latest government interventions.

“…Ozone is the most widespread air pollutant threatening agricultural production, biodiversity, and ecosystem services more than any other air pollutant at large spatial scales from national and regional to the entire globe (Tang et al 2013;Anav et al 2016;Mills et al 2018b;Agathokleous et al 2020;Sicard et al 2020;Xu 2021). It is also the second most important air pollutant negatively affecting human health after particulate matter (Brauer et al 2016;Zhang, Wei, and Fang 2019;Orru et al 2019).…”

“…Therefore, the article is focused on countries for which there is sufficient available scientific information, e.g., China, India, and Japan. Furthermore, the article is not directed to discuss technical information covered in existing publications (Yamaguchi et al 2011;Koike et al 2013;Oksanen et al 2013;Izuta 2017;Mukherjee et al 2021;Xu 2021). It is directed to provide to policymakers, scientists working in different research areas, and other stakeholders an integrated synthesis of the issue in Asia, so to translate scientific knowledge into practical actions aiming at protecting the health of both natural ecosystems and managed agroecosystems.…”

Context: Ozone concentrations near the land surface are rising in Asia while they are declining or stagnating in Europe and North America. Ozone is the most widespread air pollutant negatively affecting vegetation, and its increased concentrations pose a major threat to food quality and production and other ecosystem services in Asia. Method: In this review, we provide an overview of scientific challenges in the impacts of ozone pollution on Asian vegetation, and synthesize the challenges toward mitigation of the impacts. Result: We argue that new policy initiatives need to seek both reduction of ozone levels and enhancement of plant tolerance to ozone to maintain food quality and ensure food supplies. Conclusion:The scientific advancements must be transferred to actions by two types of institutions: a) environmental agencies for reducing ozone levels and b) agricultural research institutions for enhancing plant tolerance to ozone. In connecting the scientific advancements with the institutional actions, scientists in Asian countries should play the key role taking advantages of interdisciplinary and international collaborations.
