L.; MOYSES, E. P.; TOUFEN, C.; PEREIRA, L. A.; SALDIVA, P. H. N.; BRAGA, A. L.; ARBEX, M. A.- Environmental air pollution: respiratory effects(2021) SANTOS, Ubiratan de Paula; ARBEX, Marcos Abdo; BRAGA, Alfesio Luis Ferreira; MIZUTANI, Rafael Futoshi; CANCADO, Jose Eduardo Delfini; TERRA-FILHO, Mario; CHATKIN, Jose MiguelEnvironmental air pollution is a major risk factor for morbidity and mortality worldwide. Environmental air pollution has a direct impact on human health, being responsible for an increase in the incidence of and number of deaths due to cardiopulmonary, neoplastic, and metabolic diseases; it also contributes to global warming and the consequent climate change associated with extreme events and environmental imbalances. In this review, we present articles that show the impact that exposure to different sources and types of air pollutants has on the respiratory system; we present the acute effects-such as increases in symptoms and in the number of emergency room visits, hospitalizations, and deaths-and the chronic effects-such as increases in the incidence of asthma, COPD, and lung cancer, as well as a rapid decline in lung function. The effects of air pollution in more susceptible populations and the effects associated with physical exercise in polluted environments are also presented and discussed. Finally, we present the major studies on the subject conducted in Brazil. Health care and disease prevention services should be aware of this important risk factor in order to counsel more susceptible individuals about protective measures that can facilitate their treatment, as well as promoting the adoption of environmental measures that contribute to the reduction of such emissions.
- Evaluation of peak expiratory flow in adolescents and its association with inhalable particulate in a Brazilian medium-sized city(2018) MISSAGIA, Suelem; AMARAL, Camila Alves Silva do; JESUS, Alessandra Santos de; ARBEX, Marcos Abdo; SANTOS, Ubiratan de Paula; ANDRÉ, Carmem Diva Saldiva de; ANDRÉ, Paulo Afonso de; SALDIVA, Paulo Hilário do Nascimento; MARTINS, Lourdes Conceição; BRAGA, Alfésio Luís Ferreira; PEREIRA, Luiz Alberto AmadorABSTRACT: Introduction: High particulate matter (PM10) concentrations are associated with increased incidence of respiratory symptoms and decreased lung function. This study evaluates the air pollution effects in children’s and adolescents’ lung function using peak expiratory flow (PEF) measurements over a given period, in an area exposed to industrial emissions. Methodology: This was a panel study. The effects of air pollution on respiratory symptoms and PEF were investigated in 117 children and adolescents from three public schools in areas of exposure to air pollution from a mining company in a Brazilian medium-sized city, from 2008 to 2009. The average daily PM10, temperature and humidity were recorded by the monitoring network in the region. Association between daily records of PEF and PM10 was assessed in mixed-effect regression models, controlling for temperature, humidity, and body mass index. Results: About 60,000 PEF measurements were performed. Increases of 14µg/m3 in PM10 were associated with decreased PEF in the morning (-1.04%, 95%CI -1.32; -0.77) and evening (-1.2%, 95%CI -1.49, -0.92). Discussion: We found a significant negative association between particulate matter and peak expiratory flow rate in this population, and these remained significant even after adjusted for temperature, humidity, body mass index, coughing, wheezing and coryza. Conclusion: Adverse effects were found and it suggests an association between increase in PM10 and reduced lung function.
- Pre-harvest cane burning and health: the association between school absences and burning sugarcane fields(2015) MAURO, Carla Cabrini; FERRANTE, Vera Lucia Silveira Bota; ARBEX, Marcos Abdo; RIBEIRO, Maria Lucia; MAGNANI, RomeuThe objective of this study was to investigate an association between pre-harvest sugarcane burning and respiratory diseases in children under five years of age. The following data were collected in five schools in the city of Araraquara, SP, Southeastern Brazil, between March and June 2009: daily records of absences and the reasons stated for these absences, total concentration of suspended particulate matter (mu g/m(3)), and air humidity. The relationship between the percentage of school absences due to respiratory problems and the concentration of particulate matter in March and from April to June presented a distinct behavior: absences increased alongside the increase in particulate matter concentration. The use of school absences as indicators of this relationship is an innovative approach.
- A poluição do ar e o sistema respiratório(2012) ARBEX, Marcos Abdo; SANTOS, Ubiratan de Paula; MARTINS, Lourdes Conceicao; SALDIVA, Paulo Hilario Nascimento; PEREIRA, Luiz Alberto Amador; BRAGA, Alfesio Luis FerreiraOver the past 250 years since the Industrial Revolution accelerated the process of pollutant emission, which, until then, had been limited to the domestic use of fuels (mineral and vegetal) and intermittent volcanic emissions air pollution has been present in various scenarios. Today, approximately 50% of the people in the world live in cities and urban areas and are exposed to progressively higher levels of air pollutants. This is a non-systematic review on the different types and sources of air pollutants, as well as on the respiratory effects attributed to exposure to such contaminants. Aggravation of the symptoms of disease, together with increases in the demand for emergency treatment, the number of hospitalizations, and the number of deaths, can be attributed to particulate and gaseous pollutants, emitted by various sources. Chronic exposure to air pollutants not only causes decompensation of pre-existing diseases but also increases the number of new cases of asthma, COPD, and lung cancer, even in rural areas. Air pollutants now rival tobacco smoke as the leading risk factor for these diseases. We hope that we can impress upon pulmonologists and clinicians the relevance of investigating exposure to air pollutants and of recognizing this as a risk factor that should be taken into account in the adoption of best practices for the control of the acute decompensation of respiratory diseases and for maintenance treatment between exacerbations.
bookPart Queima de biomassa: Impactos ambiental e ocupacional(2014) ARBEX, Marcos Abdo; CASTRO, Hermano Albuquerque de- The effect of air pollution on pneumonia-related emergency department visits in a region of extensive sugar cane plantations: a 30-month time-series study(2014) ARBEX, Marcos Abdo; PEREIRA, Luiz Alberto Amador; CARVALHO-OLIVEIRA, Regiane; SALDIVA, Paulo Hilario do Nascimento; BRAGA, Alfesio Luis FerreiraBackground In Brazil, many cities are surrounded by sugar cane plantations, and when these plantations are burnt prior to harvesting, millions of people are exposed to the smoke from these fires from May to November every year. Methods A daily time-series regression analysis was conducted in a city located in the sugar cane plantation region of Sao Paulo State, Brazil, between 1 February 2005 and 31 July 2007. The percentage increase in the number of pneumonia-related emergency department visits (PEDV) associated with a 10 mu g/m(3) increase in the total suspended particles (TSP) concentration was measured, including any effects that were delayed for up to 6 days. Results A total of 1505 PEDV (a median of two events per day) were analysed. During the burning period, there was an acute effect that began on the day of exposure and remained for 2 days. An increase of 6% (95% CI 2.4 to 9.9) in PEDV was observed for the 2 days following the TSP increase. This pattern and the size of the effect were similar to those observed for the whole period and also during the non-burning period. Conclusions Increases in TSP concentrations were found to be associated with increased PEDV in a region affected by air pollution from sugar cane burning. This finding reinforces the need for polices and efforts to ban sugar cane burning prior to harvesting.
