The mineralogical composition of coarse and fine particulate material, their fate, and sources in an industrialized region of southeastern Brazil

Settleable atmospheric particulate matter affects the swimming performance and aerobic metabolic rate of Nile tilapia (Oreochromis niloticus)

“…The analysis of SePM confirmed that the contamination is highly complex in metal composition. The observed range of metals corroborates the results of previous studies (Galvão et al, 2022;Soares et al, 2022;Souza et al, 2021a;Souza et al, 2021). Metals have a broad range of impacts on fish physiology, including oxidative stress, genotoxicity, hematological alterations, histopathological alterations in many organs, and problems in diverse physiological systems (Lushchak, 2011;Pyle et al, 2002;Taylor et al, 1996;Giles, 1984).…”

Air Quality Characterization and Trend Analysis in a Brazilian Industrialized Metropolitan Area in the Period from 1995 to 2022

“…Alongside pollution from urban sources, the region contends with an extensive industrial complex, further exacerbating air pollution challenges. As confirmed by Galvão et al [45], in another industrialized region of southeastern Brazil, the mineral phases present in particulate matter are dependent on particle size. Hematite and quartz were found in significant amounts in the Settleable Particulate Matter (SPM) and in the Total Suspended Particles (TSP), whereas elemental carbon, sulfates, and halite were found in higher levels in the PM 10 and PM 2.5 fractions [45].…”

This highlights the complexity of particulate matter composition and its potential implications for human health, as health risks are also influenced by PM size [18].…”

Efeitos da exposição a poluição ambiental advinda da pelotização do minério de ferro na inflamação pulmonar alérgica crônica: possível participação do sistema colinérgico na mecânica pulmonar, inflamação, remodelamento da matriz extracelular e no estresse oxidativo em camundongos geneticamente modificados

“…A região é altamente industrializada com mais de uma centena de indústrias/atividades responsáveis pela emissão de 1.305,1 kg h−1 de PM na atmosfera, sendo 60% emitidos como PM10 (805,4 kg h−1) e 40% como PM2,5 (515,6 kg h−1), sendo que as atividades mais impactantes são as siderúrgicas e as pelotizadoras que estão localizadas no complexo industrial, sendo responsáveis por aproximadamente 70% de todas as emissões de MP da região (51). A siderúrgica tem capacidade nominal para produzir 7 milhões de toneladas de aço por ano, incluindo a produção de cerca de 3 milhões de toneladas de carvão e cerca de 5,5 milhões de toneladas de sintetização de minério de ferro (52).…”
