- GREEN AREAS AND VITAMIN D STATUS: ANALYSIS WITH WOMEN LIVING IN A MEDIUM-SIZED CITY WITH A TROPICAL CLIMATE(2022) SANTANA, Keila Valente de Souza de; OLIVER, Sofia Lizarralde; MAUAD, Thais; OLIVEIRA, Maria Aparecida de; MOREIRA, Tiana Carla Lopes; LANHAM-NEW, Susan; RIBEIRO, HelenaVitamin D deficiency is a global health problem and approaches that consider Nature-Based Solu-tions (NbS) can bring new perspectives of solution. About 80% of the amount of vitamin D that the body needs is produced endogenously through exposure of the skin to ultraviolet B (UVB) radiation from sunlight. The average UVB exposure in urban areas will depend in part on the local climate and the amount of cover and types of trees. The study analyzed the association between green areas and vitamin D levels. A sample of 101 women aged 35 years and over, living in the city of Araraquara, Brazil, was analyzed. The Normalized Difference Vegetation Index (NDVI) was calculated as an indicator of exposure to green areas, being defined as the surrounding residential vegetation. A logistic regression model was used to analyze the association between residential vegetation index and vitamin D status. A statis-tically significant positive association was observed between exposure to below-median residential surrounding vegetation index and prevalence of insufficient levels of 25(HO)D (P=0,03). The study shows that lower levels of residential green are associated with a higher prevalence of vitamin D insufficiency. NbS approaches contribute to a better understanding of suitable environments for achieving good levels of vitamin D, avoiding the need for phar-maceutical supplementation of the nutrient.
- The Use of Tree Barks to Monitor Traffic Related Air Pollution: A Case Study in Sao Paulo-Brazil(2018) MOREIRA, Tiana C. L.; AMATO-LOURENCO, Luis F.; SILVA, Gisela T. da; ANDRE, Carmen D. Saldiva de; ANDRE, Paulo A. de; BARROZO, Ligia V.; SINGER, Julio M.; SALDIVA, Paulo H. N.; SAIKI, Mitiko; LOCOSSELLI, Giuliano M.The analysis of chemical elements in the barks of trees is an alternative procedure to access spatial heterogeneity of traffic related air pollution. However, the role of tree species in the characterization of the variability of airborne pollution is poorly known. We present an observational study conducted in Sao Paulo, Brazil, based on the analysis of 498 trees from three common species: Tipuana tipu, Poincianella pluviosa, and Ligustrum sp.. We considered ANCOVA models to compare the concentrations of Al, Fe, Zn, Cu, Mn, Ba, and Sin the bark (periderm) of trees located close to streets with different levels of traffic intensity controlling for the extension of nearby green areas. The expected trend of increasing elemental concentration in the bark of trees located near streets with greater traffic intensity or close to smaller green areas was only fully evidenced by T. tipu. For instance, the concentrations of Zn, Fe, Al, and Ba increase by 200, 350, 230, and 280% respectively, for trees of this species located near arterial streets when compared to those observed near local streets. On the other hand, the concentrations of Zn, Fe, Al, and Ba are reduced by 41, 45, 50, and 30%, respectively, for trees located near green areas. For P. pluviosa, the capacity to suggest an association between the tree bark concentration of chemical elements with increasing levels of air pollution and presence of green areas was only fully observed for Zn and Cu. For Ligustrum sp., weaker and sometimes non-expected associations between bark concentrations of the chemical elements and either street classification or green area extension were observed. Our results indicate that the choice of species is a key element in the use of tree barks as a biomonitoring tool in urban landscapes. Species like T. tipu, with rough and highly porous bark, are the most appropriate for such purpose.
