“…Acid radicals are formed in the leaf matrix as these oxides react with cellular water and thus affecting formation of chlorophyll molecules. Hence, such plant species may become intolerant to pollution, experience cell death and eventually die-off (Sharma & Saxena, 2022). In this study, the chlorophyll content of the plant species did not vary significant as the seasons changed, as the low leaf extract pH also causes reduction in the chlorophyll content.…”

Trees are biomonitors and sinks for air pollutants but better sinking ability comes from trees with high tolerance for air pollution. Consequently, this study investigated the Air Pollution Tolerance Index (APTI) and Anticipated Performance Index (API) of six dominant tree species around a scrap metal recycling factory in Ile-Ife, Southwest Nigeria. Biochemical and physiological parameters such as the relative water content, total chlorophyll, leaf extract pH and ascorbic acid content of the leaves of the selected tree species were determined and used to compute the APTI. The biological and socio-economic characters of each tree species were equally examined to determine the API. The APTI of the selected tree species during the dry season was in the N.laevis(11.8) >A.boonei(11.2) >S. siamea(11.0) >B. micrantha(10.8)> T. orientalis(10.6)> T. grandis(9.6). According to the API grading,N.laevisandA.booneiwere classified as “good” (62.5% each) tree species for greenbelt development for both dry and wet seasons, whileT.orientaliswas also classified as a “good” (62.5% each) tree species for greenbelt development for the wet season only. Native tree species such asN.laevis,A.booneiandT.orientalisexhibited better tolerance to gaseous pollutants and are recommended for biomonitoring environmental health and greenbelt establishment.

“…Leaf morphological traits, such as size, shape, surface texture, stomatal characteristics, epidermal wax layers, and wettability, play a crucial role in determining their proficiency in adsorbing PM (Esposito et al, 2020;Zhang et al, 2022). Some species, however, have leaves with distinct morphological characteristics, including increased roughness and a wax layer, that can elevate their efficiency in capturing particles (Li J. et al, 2021;Sharma and Saxena, 2022). Although many studies have investigated the effects of various leaf characteristics on their ability to adsorb PM in field conditions, few studies have been conducted in controlled chambers to examine PM adsorption on leaf surfaces.…”

Trees can serve as effective biofilters of Particulate matter (PM) pollution, making them valuable for managing air pollution and promoting public health. Leaves of trees can reduce PM through absorption, adsorption, and fallout mechanisms, which are influenced by species-specific characteristics and environmental factors. Although several studies have explored the impact of various leaf characteristics on their ability to adsorb PM from field conditions, few have been conducted in controlled chambers to analyze the adsorption of PM on leaf surfaces and the uptake of metal and non-metal elements from PM on leaves. To fill these knowledge gaps, this study investigated the PM adsorption and leaf characteristics of two different tree species, Pinus densiflora (an evergreen coniferous species) and Quercus acutissima (a deciduous broad-leaved species) under controlled conditions in a PM exposure chamber with a target concentration of 300 μg m−3. The main aim of this study was to measure and compare the rate of PM component (metal and non-metal elements) uptake in two species and investigate the leaf characteristics that contribute to PM adsorption. We investigated the relationship between PM adsorption and physiolog, micro-morphology, and chemical properties of the leaf surface in two species. This study used a Pearson’s correlation analysis and a principal component analysis (PCA) to evaluate correlation between PM adsorption and leaf characteristics and uptake of metal/non-metal elements in PM on leaves. This result showed that leaf characteristics such as stomatal size, leaf roughness, and wax content played a crucial role in PM10 adsorption, while physiological factors like transpiration and leaf boundary layer conductance were identified as important determinants of PM2.5 adsorption on plant leaves. It also observed significant variations in the uptake of aluminum, iron, magnesium, phosphorus, and sulfur. This study not only advances our understanding of the mechanisms behind PM adsorption by tree leaves but also underscores the importance of selecting appropriate tree species based on their leaf characteristics for urban forestry and green infrastructure projects. The ability to strategically use tree species for PM pollution mitigation highlights a practical approach to enhancing environmental sustainability and public health.

“…Dry deposition is the primary mechanism by which urban trees filter out harmful gases from the air (Cabaraban et al, 2013). With help of the stomata in their leaves, they can absorb gaseous pollutants, while capturing or trapping particulate matter in the air by other processes such as sedimentation or impaction (Gómez-Baggethun et al, 2013;Sharma and Saxena, 2022). The foliar surface serves as a resting place for particles while other surfaces, including as bark, hair, moisture, and stickiness, help to adsorb the particles on such organs (Grote et al, 2016).…”

Urban ecosystems play a crucial role in providing a wide range of services to their inhabitants, and their functioning is deeply intertwined with the effects of climate change. The present review explores the dynamic interplay between urban ecosystem services and climate change, highlighting the reciprocal relationships, impacts, and adaptation strategies associated with these phenomena. The urban environment, with its built infrastructure, green spaces, and diverse human activities, offers various ecosystem services that enhance the wellbeing and resilience of urban dwellers. Urban ecosystems offer regulatory services like temperature control, air quality upkeep, and stormwater management, plus provisioning like food and water. They also provide cultural benefits, promoting recreation and community unity. However, climate change poses significant challenges to urban ecosystem services. Rising temperatures, altered precipitation patterns, and increased frequency of extreme weather events can disrupt the functioning of urban ecosystems, impacting the provision of services. Heatwaves and urban heat island effects can compromise human health and energy demands, while changes in rainfall patterns can strain stormwater management systems and lead to flooding. Moreover, climate change can disrupt biodiversity and ecological processes, affecting the overall resilience and sustainability of urban ecosystems. To address these challenges, cities are adopting various adaptation strategies that recognize the interdependence between urban ecosystems and climate change. Green infrastructure interventions, such as the creation of urban parks, green roofs, and community gardens, aim to mitigate the impacts of climate change by enhancing the regulation of temperature, improving air quality, and reducing stormwater runoff. Additionally, urban planning and design approaches prioritize compact and walkable neighborhoods, promoting public transportation and reducing reliance on fossil fuels. Furthermore, engaging communities in the management of urban ecosystems and climate change adaptation measures is crucial for ensuring equitable distribution of ecosystem services and building social resilience. Therefore, the review article highlights a comprehensive understanding of the dynamic interrelationship between urban ecosystem services and climate change and their implications. By recognizing and integrating the contributions of urban ecosystems, cities can develop sustainable and resilient strategies to mitigate and adapt to climate change, ensuring the wellbeing and habitability of urban environments for present and future generations.
