Avaliação de parâmetros da qualidade do ar em um município amazônico do Estado do Pará

Abstract

This study evaluated the air quality in Barcarena, Pará, Brazil, throughout 2023, focusing on monitoring particulate matter concentrations (PM2.5, PM10, and TSP) at two points (P01 and P02) near an industrial complex with activities such as ore beneficiation and shipment, agricultural fertilizer storage and bagging, and grain shipment. These points were strategically chosen due to their location within the influence zone of various enterprises and the prevailing wind direction in the region. Samples were collected using High-Volume Samplers (HVS) over 24-hour periods, following guidelines from the Air Quality Technical Guide and CONAMA Resolution No. 491/2018. Collected data underwent descriptive and multivariate statistical analysis using Minitab Statistical software to determine PM2.5, PM10, and TSP concentrations and calculate the Air Quality Index (AQI). Results showed PM2.5, PM10, and TSP concentrations complied with the intermediate standards (PI-1) of CONAMA Resolution No. 491/2018 and the stricter limits of CONAMA Resolution No. 506/2024. The AQI for PM2.5 and PM10 was classified as "N1 - Good" throughout the study period, indicating no harmful effects on human health. Additionally, the study conducted a cost analysis of air quality monitoring campaigns, considering supplies, labor, and equipment, using ORÇAFASCIO software for budget development. This study contributes to air quality monitoring in areas with intense industrial activity, providing relevant data for environmental management and public health. Furthermore, the cost analysis offers valuable insights for planning and decision-making in similar projects.
