air pollution, mortality, AirQ+, PM10Abstract
Particulate matter, such as PM10, poses a threat to health and the environment. This study assessed the health impacts associated with the average annual PM concentrations in Canoas, Rio Grande do Sul, and Paulínia, São Paulo, from 2010 to 2019, comparing them to World Health Organization (WHO) guidelines. Air pollution is a global concern due to its {association} with respiratory diseases. Computational tools such as AirQ+ and Openair (R programming language) are essential for linking health and pollution data. The analyses showed a decrease in PM10 concentrations over time according to the Theil-Sen test. In Canoas, a significant reduction (p-value < 0.01) of 2.18 µg. m-3 per year was observed, while in Paulínia a reduction of 0.35 µg. m-3 per year was not significant (p-value > 0.10) and still remained above the 15 µg. m-3 recommended by the WHO. The relative risk calculation estimated that with this reduction, 4,367 and 2,351 health events could have been avoided in Canoas and Paulínia, respectively. These data highlight the need for policies to improve air quality and protect public health.
