Análise espacial e temporal da qualidade do ar no Recife/PE com o uso de sensores IQAir

Abstract

This study aims to analyze air pollution in Recife, using data from air quality monitoring sensors operated by IQAir, installed in some neighborhoods of the city of Recife. The methodology applied included the collection and statistical analysis of data on air pollutants, such as PM1.0, PM2.5 and PM10, comparing them with the standards established by CONAMA Resolution No. 506/2024. The results indicated that the annual average of pollutants was below the permitted limits, showing that, in general, air quality in the city is considered good, although variations occur during periods of high traffic and weather events. It is concluded that, despite some temporary peaks of excess pollution, the trend is towards compliance with environmental standards. However, it is essential to carry out further investigations on an ongoing basis on the calibration of the sensors and to deepen studies on the influence of climate variables on air quality, in order to ensure more accurate monitoring.
