“…Some studies have demonstrated the harmful effects of prolonged exposure of plants to atmospheric pollutants (Furlan et al, 2007;Casimiro et al, 2016). For example, Psidium guajava plants presented increasing percentage of leaf injuries when exposed to O 3 , with symptoms reaching 100% of the plants after 60 days of exposure to this pollutant (Furlan et al, 2007).…”

Psidium cattleianum is a bioindicator species of air pollutants, notably NO x and SO 2. The aim of this study was to evaluate the effects of air emissions from a mining industry in Brumado, Bahia, Brazil, on the morphophysiological characteristics of P. cattleianum. A field experiment was carried out with potted plants in two distinct areas: (1) permanent exposure to NO x and SO 2 emissions; and (2) free from the influence of the plume formed by these air pollutants (control). Plant height, leaves area and quantity, leaves, stem and roots dry mass, and chlorophyll and soluble sugar contents were evaluated. In the plants exposed to the pollutant plume, height growth inhibition and leaf size and quantity reduction were observed, besides showing symptoms of chlorosis and necrosis. Dry matter production was also lower in all organs. The chlorophyll a content was lower, but chlorophyll b content did not change. The soluble sugars content was not affected by the pollutants. It was concluded that the atmospheric emissions from the mining industry negatively affect the physiological characteristics of P. cattleianum, inhibiting the plant growth.

“…Sicard et al (2016) and Hoshika et al (2018) suggested flux-based critical levels against leaf visible injury of 20-25 mmol m −2 POD0 for forest trees. However, only a few studies had been reported for modelling stomatal O 3 flux in tropical forest trees (Cassimiro et al, 2016). To calculate POD0, we provided for the first time the parameterization of the stomatal conductance model in E. uniflora.…”

“…Consequently, more severe O 3 effects on the Atlantic forest located in this subtropical region (mainly São Paulo and Rio de Janeiro States) are expected (Domingos et al, 2003; Moura et al, 2014, 2018). Ozone effects on native tree species from the Atlantic Forest have recently been determined in the field or experimentally, pointing to distinct tolerance levels and highlighting the need to expand knowledge on this topic (Cassimiro et al, 2016; Engela et al, 2021; Fernandes et al, 2019; Moura et al, 2018). In the SH, the Amazon spans over 629 million hectares of rainforest, accounting for 54% of the total rainforests left on Earth (Peng et al, 2020).…”

Although it is an integral part of global change, most of the research addressing the effects of climate change on forests have overlooked the role of environmental pollution. Similarly, most studies investigating the effects of air pollutants on forests have generally neglected the impacts of climate change. We review the current knowledge on combined air pollution and climate change effects on global forest ecosystems and identify several key research priorities as a roadmap for the future. Specifically, we recommend (1) the establishment of much denser array of monitoring sites, particularly in the South Hemisphere; (2) further integration of ground and satellite monitoring; (3) generation of flux‐based standards and critical levels taking into account the sensitivity of dominant forest tree species; (4) long‐term monitoring of N, S, P cycles and base cations deposition together at global scale; (5) intensification of experimental studies, addressing the combined effects of different abiotic factors on forests by assuring a better representation of taxonomic and functional diversity across the ~73,000 tree species on Earth; (6) more experimental focus on phenomics and genomics; (7) improved knowledge on key processes regulating the dynamics of radionuclides in forest systems; and (8) development of models integrating air pollution and climate change data from long‐term monitoring programs.
