Abstract

High rates of pollutants are emitted daily into the atmosphere due to urban development, while thousands of dollars are spent on hospital stays in major cities. It is known the effects of exposure to air pollution in hospitalizations for diseases of the circulatory system, thus becoming a risk factor for the health of the population. The cost of these hospitalizations in a medium-sized city in Brazil generated an estimated expenditure of US $ 1.3 million in 2015. An ecological time-series study conducted in the city of Taubaté, state of São Paulo, performed with estimated data (PM2.5) [47μg / m3] and carbon monoxide (CO) [197 ppb], as well as data from hospitalizations of the environmental information system (SISAM) obtained from the portal of the Ministry of Health (1470 admissions) and categorized by gender [774], with a lag of 7 days [lag0 to lag7]. In the multi-pollutant analysis, a positive association was found for CO [male lag7] and PM2.5 [lag2, lag3 and lag4 male sex; female lag6]; with an increase of 10 μg / m3 at concentrations of pollutants, we would have a 7% increase in hospitalizations; reduction of 10 μg / m3 in these concentrations implies an approximate saving of US $ 93.3 thousand / year. All these data highlight the importance of the study of concentrations of air pollutants in the big cities, paying attention to the emission control in the atmosphere.
