Determinação de material particulado em ambiente industrial por meio de amostrador de grande volume

Abstract

This study presents an air quality analysis in an agro-industrial environment, with an emphasis on determining particulate matter (PM) concentrations and assessing their compliance with current regulatory parameters. In industrial environments, the concentration of this pollutant tends to be high, making monitoring necessary. The study sampled Total Suspended Particles (TSP) in a soybean processing industry. The objective was to evaluate whether the measured concentrations met the standards established by CONAMA Resolution No. 506/2024. The methodology adopted involved the use of a High-Volume Air Sampler (Hi-Vol), equipped with a volumetric flow controller, which was used to collect 12 TSP samples on different days over the course of a month. The results demonstrated TSP concentrations ranging from 13.43 to 170.68 µg/m³, with an average of 79.98 µg/m³, with no exceedance of the 240 µg/m³ daily limit established by CONAMA Resolution No. 506/2024. The results obtained corroborate data from a previous campaign conducted by a specialized company, showing similar behavior and orders of magnitude between the campaigns. It is concluded that the particulate matter emissions during the evaluated period were within the legislation, reinforcing the importance of regular air quality monitoring as a strategic environmental management tool.
