“…Upon entering the impactor, the sample flow is divided into two separate flow systems, and the air sample is fractionated, usually at a flow rate of 16.7 L/min, due to the acceleration that occurs in the particles. Thus, PM2.5-10 particles are directed directly to the first deposition chamber and deposited on a membrane filter, while PM2.5 particles are directed through a tube that channels the flow and are collected separately on another membrane (Costa et al, 2018). For field sampling, the "transect" method described by Filgueiras et al (1994) was applied, adapted for bird observation, where species are recorded through visual sightings and vocalizations along a route.…”

Objetivo do estudo: realizar uma análise ambiental integrada da qualidade do ar, por meio do monitoramento de poluentes atmosféricos, variáveis meteorológicas e composição da avifauna, no município de Gramado, RS. Metodologia: O estudo foi realizado em uma área urbana no município de Gramado/RS. O período amostral ocorreu entre novembro/2021 a outubro/2022. Para a coleta do material particulado (MP2,5 e MP10) foi utilizado um amostrador dicotômico, sendo realizadas 24 coletas. Os dados meteorológicos foram disponibilizados pela estação do INMET. Para o levantamento da avifauna foram realizadas 12 saídas à campo, utilizando-se o método de caminhamento. Originalidade/Relevância: O conhecimento produzido por este estudo pode contribuir como subsídio para estratégias e ações voltadas à melhor qualidade de vida, a saúde e educação ambiental. Principais resultados: Os resultados demonstraram que duas amostras de MP2,5 e seis amostras de MP2,5-10 ficaram em desconformidade com as diretrizes de qualidade do ar estabelecidos pela OMS. Por meio do modelo de regressão linear verificou-se que 83,9% da variação do MP10 é explicada pelo aumento da temperatura máxima. Ao longo do período de amostragens foram registradas a ocorrência de 45 espécies de aves. As maiores riquezas de espécies ocorreram em setembro/2022 (35) e outubro/2022 (32), onde 37,4% da variação do número de aves pode ser explicado pela precipitação. Para os demais dados não houve relação. Contribuições: Os resultados poderão ser utilizados para realização de medidas de promoção da saúde ambiental, prevenção e controle dos fatores de riscos relacionados a qualidade do ar.

“…The equipment performs the inertial separation of ne and coarse particles by a virtual impactor, dividing the sample ow into two separate systems and fractioning the air sample at a sampling ow rate of 900 L min − 1 (PM 2.5 ) and 100 L min − 1 (PM 2.5−10 ). The PM 2.5−10 particles are directed to the rst deposition layer and deposited on a 47 mm diameter polycarbonate membrane lter, while the PM 2.5 particles are collected separately in another membrane with the same speci cation (Costa et al, 2018).…”

Atmospheric pollution is one of the main consequences of anthropogenic activities in the environment. The insertion of particles suspended in the air, which are composed of dust, fumes, microplastics, and aerosols emitted by industries, vehicles, and constructions, alters the quality of the environment they are inserted into, impacting both human health and the environment. Therefore, this study aims to identify the atmospheric particles that may be influencing the air quality in the Region of Hortênsias/RS (municipalities of Canela and Gramado). The concentrations of PM2.5 and PM2.5−10 were evaluated at two sites from April 2021 to April 2022. The Fine and Coarse Particulate Matter Sampler (FCS) was used to collect samples at the site located in Canela (S1). In Gramado (S2), in addition to the FCS, a dichotomous sampler was also used for sampling. The filters were observed under a microscope to evaluate the presence of polymeric material. The selected particles were then analyzed by Scanning Electron Microscopy (SEM) coupled with Energy Dispersive X-Ray Spectroscopy (EDS). Six samples of PM2.5 did not meet the air quality standards recommended by the WHO Guideline. Alterations in the concentrations of PM2.5 were also observed in October and December 2021 at S1 and S2 and in April 2022 at S2. The results demonstrated low air quality, and the microscopic analysis detected the presence of particles with characteristics of polymeric material. These particles suggest traces of microplastics, in addition to the presence of vehicular soot and fly ash when analyzed by SEM/EDS.
