“…Between 2010 and 2014, the highest mean ozone values were measured in the southern USA, Mediterranean Basin, northern India, northwestern and eastern China, Republic of Korea, and Japan [ 6 ]. Densely populated regions in emerging countries have become major ozone pollution hotspots [ 7 , 8 , 9 , 10 , 11 ]. Abatements in emissions of nitrogen oxides (NO x ) and volatile organic compound (VOC) precursors in Europe, North America, and Japan since the end of the last century have resulted in a reduction of ozone peaks, but they have been unable to curb an increase in background ozone concentrations and plant uptake [ 12 , 13 , 14 , 15 ].…”

With the current increases in environmental stress, understanding species-specific responses to multiple stress agents is needed. This science is especially important for managing ecosystems that are already confronted with considerable pollution. In this study, responses to ozone (O3, ambient daily course values + 20 ppb) and mixed metal contamination in soils (MC, cadmium/copper/lead/zinc = 25/1100/2500/1600 mg kg−1), separately and in combination, were evaluated for three plant species (Picea abies, Acer pseudoplatanus, Tanacetum vulgare) with different life forms and ecological strategies. The two treatments elicited similar stress reactions, as shown by leaf functional traits, gas exchange, tannin, and nutrient markers, irrespective of the plant species and life form, whereas the reactions to the treatments differed in magnitude. Visible and microscopic injuries at the organ or cell level appeared along the penetration route of ozone and metal contamination. At the whole plant level, the MC treatment caused more severe injuries than the O3 treatment and few interactions were observed between the two stress factors. Picea trees, with a slow-return strategy, showed the highest stress tolerance in apparent relation to an enhancement of conservative traits and an exclusion of stress agents. The ruderal and more acquisitive Tanacetum forbs translocated large amounts of contaminants above ground, which may be of concern in a phytostabilisation context. The deciduous Acer trees—also with an acquisitive strategy—were most sensitive to both stress factors. Hence, species with slow-return strategies may be of particular interest for managing metal-polluted sites in the current context of multiple stressors and for safely confining soil contaminants below ground.

“…The RJMR is the second largest among the 74 metropolitan areas in Brazil (IBGE 2020) and presents the second-highest concentration of industries and vehicles in the country (INEA 2015). These aspects in conjunction with the heterogeneity of land use and land cover, and anthropogenic source location, wind regime spatial and temporal variability, and complex topography play an important role in the atmospheric pollutant dispersion modeling in the non-homogeneous Rio de Janeiro Metropolitan Region (RJMR) (Pimentel et al 2014a, b;Paiva et al 2014;Silveira et al 2021). Also valuable is the use of AQ models to design and support the local observation network and depict violations of air quality standards, as well as to establish and guide public policies for urban -industrial planning and RMRJ environmental protection areas (Silveira et al 2021).…”

Air quality models are essential tools to meet the United Nations Sustainable Development Goals (UN-SDG) because they are effective in guiding public policies for the management of air pollutant emissions and their impacts on the environment and human health. Despite its importance, Brazil still lacks a guide for choosing and setting air quality models for regulatory purposes. Based on this, the current research aims to assess the combined WRF/CALMET/CALPUFF models for representing SO2 dispersion over non-homogeneous regions as a regulatory model for policies in Brazilian Metropolitan Regions to satisfy the UN-SDG. The combined system was applied to the Rio de Janeiro Metropolitan Region (RJMR), which is known for its physiographic complexity. In the rst step, the WRF model was evaluated against surface-observed data. The local circulation was underestimated, while the prevailing observational winds were well-represented. In the second step, it was veri ed that all CALMET three meteorological con gurations performed better for the most frequent wind speed classes, so that the largest SO2 concentrations errors occurred during light winds. Among the meteorological settings in WRF/CALMET/CALPUFF, the joined use of observed and modeled meteorological data yielded the best results for the dispersion of pollutants. This result emphasizes the relevance of meteorological data composition in complex regions with unsatisfactory monitoring given the inherent limitations of prognostic models and the excessive extrapolation of observed data that can generate distortions of reality. This research concludes with the proposal of the WRF/CALMET/CALPUFF air quality regulatory system as a supporting tool for policies in the Brazilian Metropolitan Regions in the framework of the UN-SDG, particularly in non-homogeneous regions where steady-state Gaussian models are not applicable.

“…However, studies relating the concentrations of O 3 , NO 2 , re occurrences, and climatic conditions are scarce in underdeveloped countries. In Brazil, for example, problems associated with the degradation of air quality via the analysis of O 3 and/or NO 2 concentrations have been investigated in large urban centers such as São Paulo (Carvalho et al 2020), Rio de Janeiro (Siciliano et al 2020;Silveira et al 2020). In the Center-West of Brazil, agricultural and industrial activities and urbanization are growing, which in turn change the patterns of O 3 and NO 2 in the region.…”

“…Air pollution/air quality, climate change, deforestation, and, environmental degradation are the main challenges in the world. The ozone (O 3 ) and nitrogen dioxide (NO 2 ) are the main urban air pollutants (Souza and Ozonur, 2019;Silveira et al, 2020). The O 3 is one of the main greenhouse gases (GHG) and plays an important role in our climate system (Silveira et al, 2020).…”

The total column ozone (O3) and nitrogen dioxide (NO2) levels based on the satellite remote sensing for a period from 2005 to 2020 along with air temperature, rainfall and burned area in three biomes (Cerrado, Pantanal, and Atlantic Forest) from Mato Grosso do Sul - Brazil was evaluated. The annual variations of O3 ranged from 260 DU for the Pantanal to 347 DU for the Cerrado. Whereas the NO2 concentrations ranged from 2.95×1015 molecules for the Cerrado to 3.01×1015 molecules for the Atlantic Forest. The differences between NO2 and O3 concentrations on monthly and seasonal time scales, with higher values during the dry period (between July and October). The NO2 and O3 concentrations positively correlated with the burn areas in Pantanal and Cerrado, while the rainfall negatively correlated with these gases’ concentrations in these biomes The first principal component in all biomes is a comparison between rainfall and NO2, O3, a burned area, and air temperature with higher values of eigenvalues for the burned area in Pantanal, followed by Cerrado and Atlantic Forest, indicating more fires in Pantanal. Rainfall showed the highest value in the first principal components (PC). The second component in the Atlantic Forest was a balance between rainfall and air temperature with NO2, O3 and burned area. In the Cerrado and Pantanal, a comparison is made between burned area and NO2, with rainfall, air temperature and O3. There are differences in the behavior of NO2 and O3 concentrations in biomes, driven by different environmental and anthropic variables.
