📄 Abstract（原文）
Growing urban development, characterized by the suppression of tree vegetation in favor of increased paved areas and buildings, has contributed to the accumulation of anthropogenic carbon in the atmosphere. This study aimed to estimate the carbon sequestered by trees along an urban avenue, highlighting the importance of afforestation for improving air quality and human health. A floristic list of tree species was obtained following taxonomic identification, along with individual densities. Atmospheric pollutants, including carbon monoxide and dioxide (ppm), volatile organic compounds and formaldehyde (?g m-3), particulate matter (PM2.5, PM10), and nitrogen dioxide, were estimated. The total carbon equivalent sequestered from the atmosphere was obtained. A total of 505 adult trees, native and exotic trees and palms, are distributed across 11 botanical families, 27 genera, and 29 species, with a particular emphasis on the Fabaceae family. The species with the largest number of individuals were Elaeis guineensis (106 palms), Terminalia catappa (70 trees), and Senna spectabilis var. excelsa (60 trees). The leaf blade form defined two functional groups. Palisade layer thickness and the presence of crystals are associated with plant responses to biomass production and pollution, respectively. The total carbon equivalent sequestered from the atmosphere in one year corresponded to 2,171.5 kg of CO2-eq or 0.54 tons of carbon (540 kg). The results reinforced the fundamental importance of preserving and expanding urban tree cover as an effective tool to minimize the effects of climate change, mitigate pollution, and promote sustainable, healthy urban environments. This, in turn, enhances the quality of human life, aligning with the Sustainable Development Goals (SDGs) of the 2030 Agenda.
