- Effectiveness of traffic-related elements in tree bark and pollen abortion rates for assessing air pollution exposure on respiratory mortality rates(2017) CARVALHO-OLIVEIRA, Regiani; AMATO-LOURENCO, Luis F.; MOREIRA, Tiana C. L.; SILVA, Douglas R. Rocha; VIEIRA, Bruna D.; MAUAD, Thais; SAIKI, Mitiko; SALDIVA, Paulo H. NascimentoThe majority of epidemiological studies correlate the cardiorespiratory effects of air pollution exposure by considering the concentrations of pollutants measured from conventional monitoring networks. The conventional air quality monitoring methods are expensive, and their data are insufficient for providing good spatial resolution. We hypothesized that bioassays using plants could effectively determine pollutant gradients, thus helping to assess the risks associated with air pollution exposure. The study regions were determined from different prevalent respiratory death distributions in the Sao Paulo municipality. Samples of tree flower buds were collected from twelve sites in four regional districts. The genotoxic effects caused by air pollution were tested through a pollen abortion bioassay. Elements derived from vehicular traffic that accumulated in tree barks were determined using energy-dispersive X-ray fluorescence spectrometry (EDXRF). Mortality data were collected from the mortality information program of Sao Paulo City. Principal component analysis (PCA) was applied to the concentrations of elements accumulated in tree barks. Pearson correlation and exponential regression were performed considering the elements, pollen abortion rates and mortality data. PCA identified five factors, of which four represented elements related to vehicular traffic. The elements Al, S, Fe, Mn, Cu, and Zn showed a strong correlation with mortality rates (R-2>0.87) and pollen abortion rates (R-2>0.82). These results demonstrate that tree barks and pollen abortion rates allow for correlations between vehicular traffic emissions and associated outcomes such as genotoxic effects and mortality data.
- The influence of atmospheric particles on the elemental content of vegetables in urban gardens of Sao Paulo, Brazil(2016) AMATO-LOURENCO, Luis Fernando; MOREIRA, Tiana Carla Lopes; SOUZA, Vanessa Cristina de Oliveira; BARBOSA JR., Fernando; SAIKI, Mitiko; SALDIVA, Paulo Hilario Nascimento; MAUAD, ThaisAlthough urban horticulture provides multiple benefits to society, the extent to which these vegetables are contaminated by the absorption of chemical elements derived from atmospheric deposition is unclear. This study was designed to evaluate the influence of air pollution on leafy vegetables in community gardens of Sao Paulo, Brazil. Vegetable seedlings of Brassica oleracea var. acephala (collard greens) and Spinacia oleracea (spinach) obtained in a non-polluted rural area and growing in vessels containing standard uncontaminated soil were exposed for three consecutive periods of 30, 60 and 90 days in 10 community gardens in Sao Paulo and in one control site. The concentrations of 17 chemical elements (traffic-related elements and those essential to plant biology) were quantified by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Tillandsia usneoides L. specimens were used as air plant biomonitors. The concentrations of As, Cd, Cr and Pb found in vegetables were compared to the recommended values for consumption. Principal Component Analysis (PCA) was used to cluster the elemental concentrations, and Generalized Linear Models (GLMs) were employed to evaluate the association of the factor scores from each PCA component with variables such as local weather, traffic burden and vertical barriers adjacent to the gardens. We found significant differences in the elemental concentrations of the vegetables in the different community gardens. These differences were related to the overall traffic burden, vertical obstacles and local weather. The Pb and Cd concentrations,in both vegetables exceeded the limit values for consumption after 60 days of exposure. A strong correlation was observed between the concentration of traffic-related elements in vegetables and in Tillandsia usneoides L An exposure response was observed between traffic burden and traffic-derived particles absorbed in the vegetables. Traffic-derived air pollution directly influences the absorption of chemical elements in leafy vegetables, and the levels of these elements may exceed the recommended values for consumption.
- Intra-urban biomonitoring: Source apportionment using tree barks to identify air pollution sources(2016) MOREIRA, Tiana Carla Lopes; OLIVEIRA, Regiani Carvalho de; AMATO, Luis Fernando Lourenco; KANG, Choong-Min; SALDIVA, Paulo Hilario Nascimento; SAIKI, MitikoIt is of great interest to evaluate if there is a relationship between possible sources and trace elements using biomonitoring techniques. In this study, tree bark samples of 171 trees were collected using a biomonitoring technique in the inner city of Sao Paulo. The trace elements (Al, Ba, Ca, Cl, Cu, Fe, K, Mg, Mn, Na, P, Rb, S, Sr and Zn) were determined by the energy dispersive X-ray fluorescence (EDXRF) spectrometry. The Principal Component Analysis (PCA) was applied to identify the plausible sources associated with tree bark measurements. The greatest source was vehicle-induced non-tailpipe emissions derived mainly from brakes and tires wear-out and road dust resuspension (characterized with Al, Ba, Cu, Fe, Mn and Zn), which was explained by 27.1% of the variance, followed by cement (14.8%), sea salt (11.6%) and biomass burning (10%), and fossil fuel combustion (9.8%). We also verified that the elements related to vehicular emission showed different concentrations at different sites of the same street, which might be helpful for a new street classification according to the emission source. The spatial distribution maps of element concentrations were obtained to evaluate the different levels of pollution in streets and avenues. Results indicated that biomonitoring techniques using tree bark can be applied to evaluate dispersion of air pollution and provide reliable data for the further epidemiological studies.

- Clinical, sociodemographic and environmental factors impact post-COVID-19 syndrome(2022) FERREIRA, Juliana Carvalho; MOREIRA, Tiana C. Lopes; ARAUJO, Adriana Ladeira de; IMAMURA, Marta; DAMIANO, Rodolfo F.; GARCIA, Michelle L.; SAWAMURA, Marcio V. Y.; PINNA, Fabio R.; GUEDES, Bruno F.; GONCALVES, Fabio A. Rodrigues; MANCINI, Marcio; BURDMANN, Emmanuel A.; SILVA FILHO, Demostenes Ferreira da; POLIZEL, Jefferson Lordello; BENTO, Ricardo F.; ROCHA, Vanderson; NITRINI, Ricardo; SOUZA, Heraldo Possolo de; LEVIN, Anna S.; KALLAS, Esper G.; FORLENZA, Orestes V.; BUSATTO, Geraldo F.; BATISTELLA, Linamara R.; CARVALHO, Carlos R. Ribeiro de; MAUAD, Thais; GOUVEIA, NelsonBackground Sociodemographic and environmental factors are associat-ed with incidence, severity, and mortality of COVID-19. However, little is known about the role of such factors in persisting symptoms among re-covering patients. We designed a cohort study of hospitalized COVID-19 survivors to describe persistent symptoms and identify factors associated with post-COVID-19 syndrome. Methods We included patients hospitalized between March to August 2020 who were alive six months after hospitalization. We collected indi-vidual and clinical characteristics during hospitalization and at follow-up assessed ten symptoms with standardized scales, 19 yes/no symptoms, a functional status and a quality-of-life scale and performed four clinical tests. We examined individual exposure to greenspace and air pollution and considered neighbourhood acute accent s population density and socioeconomic conditions as contextual factors in multilevel regression analysis. Results We included 749 patients with a median follow-up of 200 (IQR = 185-235) days, and 618 (83%) had at least one of the ten symptoms measured with scales. Pain (41%), fatigue (38%) and posttraumatic stress disorder (35%) were the most frequent. COVID-19 severity, comorbidities, BMI, female sex, younger age, and low socioeconomic position were associ-ated with different symptoms. Exposure to ambient air pollution was asso-ciated with higher dyspnoea and fatigue scores and lower functional status. Conclusions We identified a high frequency of persistent symptoms among COVID-19 survivors that were associated with clinical, sociodemographic, and environmental variables. These findings indicate that most patients re-covering from COVID-19 will need post-discharge care, and an additional burden to health care systems, especially in LMICs, should be expected.
- Metrópoles, cobertura vegetal, áreas verdes e saúde(2016) AMATO-LOURENÇO, Luís Fernando; MOREIRA, Tiana Carla Lopes; ARANTES, Bruna Lara de; SILVA FILHO, Demóstenes Ferreira da; MAUAD, ThaisThe lack of planning in the urbanization process of big cities worldwide has produced numerous negative externalities, including the suppression of vegetation and green spaces. Multiple benefits have been reported on how urban vegetation promotes and influences environmental, social and economic factors, as well as people's health. This paper presents a series of studies focusing on the association between urban vegetation and human health, as well as a brief reflection on the importance of this issue in the city of São Paulo.
- Spatial-temporal variability of metal pollution across an industrial district, evidencing the environmental inequality in Sao Paulo(2020) LOCOSSELLI, Giuliano Maselli; MOREIRA, Tiana Carla Lopes; CHACON-MADRIZ, Katherine; ARRUDA, Marco Aurelio Zezzi; CAMARGO, Evelyn Pereira de; KAMIGAUTI, Leonardo Yoshiaki; TRINDADE, Ricardo Ivan Ferreira da; ANDRADE, Maria de Fatima; ANDRE, Carmen Diva Saldiva de; ANDRE, Paulo Afonso de; SINGER, Julio M.; SAIKI, Mitiko; ZACCARELLI-MARINO, Maria Angela; SALDIVA, Paulo Hilario Nascimento; BUCKERIDGE, Marcos SilveiraAlthough air pollution decreased in some cities that shifted from an industrial to a service-based economy, and vehicular emission regulation became more restrictive, it is still a major risk factor for mortality worldwide. In central Sao Paulo, Brazil, air quality monitoring stations and tree-ring analyses revealed a decreasing trend in the concentrations of particulate matter and metals. Such trends, however, may not be observed in industrial districts located in the urban periphery, where the usual mobile sources may be combined with local stationary sources. To evaluate environmental pollution in an industrial district in southeastern Sao Paulo, we assessed its spatial variability, by measuring magnetic properties and concentrations of Al, Ba, Ca, Cl, Cu, Fe, K, Mg, Mn, P, S, Sr, Zn in the bark of 62 trees, and its temporal trends, by measuring Cd, Cu, Ni, Pb, V, Zn in tree rings of three trees. Source apportionment analysis based on tree barks revealed two clusters with high concentrations of metals, one related to vehicular and industrial emissions (Al, Ba, Cu, Fe, Zn) in the east side of the industrial cluster, and the other related to soil resuspension (Cu, Zn, Mn) in its west side. These patterns are also supported by the magnetic properties of bark associated with iron oxides and titanium-iron alloy concentrations. Dendrochemical analyses revealed that only the concentrations of Pb consistently decreased over the last four decades. The concentrations of Cd, Cu, Ni, V, and Zn did not significantly decrease over time, in contrast with their negative trends previously reported in central Sao Paulo. This combined biomonitoring approach revealed spatial clusters of metal concentration in the vicinity of this industrial cluster and showed that the local population has not benefited from the decreasing polluting metal concentrations in the last decades.
- Effects of Air Pollution in S($)over-tilde-$ao Paulo on Asthma and COPD symptoms(2022) ALMEIDA, F. M.; MOREIRA, T. C. L.; OLIVEIRA, L. M.; RIGHETTI, R. F.; LOPES, F. D. T. Q. S.; ALENCAR, A. P.; MAUAD, T.; GOUVEIA, N. C.; LOTUFO, P. A.; BENSENOR, I.; SANTOS, I. S.; TIBERIO, I. F. L. C.
- Biomonitoring of genotoxic effects and elemental accumulation derived from air pollution in community urban gardens(2017) AMATO-LOURENCO, Luis Fernando; LOBO, Debora Ja A.; GUIMARAES, Eliane T.; MOREIRA, Tiana Carla Lopes; CARVALHO-OLIVEIRA, Regiani; SAIKI, Mitiko; SALDIVA, Paulo Hilario Nascimento; MAUAD, ThaisUrban gardening is a growing global phenomenon with a positive impact on society. Despite several associated benefits, growing vegetables in urban gardens that are localized in highly polluted areas poses questions about the safety of the produced food. Therefore, the identification of risk factors that result in possible deleterious effects to human health is important for realizing all of the benefits to society. We evaluated the use of two-biomonitoring methods in ten urban gardens of Sao Paulo city and one control site: the micronuclei frequencies for early tetrads of Tradescantia pallida (Rose) Hunt. cv. ""Purpurea"" Boom(hereafter, Trad-MCN) as a short-term indicator of genotoxic response and tree barks to quantify the accumulation of traffic-related chemical elements as a long-term biomarker of air pollution in urban gardens. Mature plants of Tradescantia pallida were exposed in each garden, and their inflorescences were sampled over three months. A random set of 300 early tetrads in 13 to 21 slides per garden were evaluated for micronuclei frequencies. Elemental concentrations in 428 tree barks samples from 107 different trees in the areas surrounding urban gardens were quantified using an energy dispersive X-ray fluorescence spectrometer. The frequency of Trad-MCN has a significant correlation with traffic variables and chemical elements related to road dust and tailpipe emissions deposited in tree barks. Negative associations between Trad-MCN and both the distance through traffic and the presence of vertical obstacles were observed in the community gardens. The Mn/Zn concentrations in tree barks were associated with increased Trad-MCN.
