1. Assessment of Atmospheric PM10 Pollution Levels and Chemical Composition in Urban Areas near the 2016 Olympic Game Arenas
Coarse particulate matter (PM10) concentrations and chemical composition were monitored from 2014 to 2017 at three sampling sites in the Metropolitan Region of Rio de Janeiro, namely Botafogo, Gávea, and Gericinó. All sites are located close to the 2016 Olympic Game arenas. The average annual PM10 concentrations were above the limits recommended by the Wor

3. Caracterização do material particulado em Cubatão / CHARACTERIZATION OF PARTICULATE MATTER IN CUBATÃO
This work evaluated the particulate matter (PM) collected at the Environmental Research and Training Center (CEPEMA) located in Cubatão City. Sampling was made between 2009, March and 2010, November for fine, coarse and inhalable aerosol (Mini-Vol) and for the various fractions of PM with a cascade impactor (MOUDI) during eight experimental campaigns. A cli

4. Determinação de metais traço no material particulado em suspensão em Ouro Preto, Minas Gerais
The determination of the airborne particulate matter (PTS) mass and trace metals concentrations were performed in three sites in Ouro Preto, MG, Brazil. It was evaluated 288 samples. The legal limit of annual geometric average (60 µg m-3) to PTS concentrations didn't exceed, but the legal limit for 24 h (240 µg m-3) did in three measurements. Seven metals

5. Determinação da concentração de elementos químicos potencialmente tóxicos em aerossóis presentes no interior de uma pequena indústria de fundição de metais, utilizando amostrador temporal e a técnica de fluorescência de raios X / Toxic inorganic elements content in suspended particulate matter inside a small foundry plant by streaker sampler and energy dispersive X-ray fluorescence technique
The aim of this work was to evaluate the chemical concentration of some potentially toxic inorganic chemical elements and the time profiles in fine (PM2.5, particles up to 2.5 m) and coarse (PM2.5-10, particles from 2.5 to 10 m) suspended particulate matter (SPM) inside a small foundry plant - bronze, iron and aluminium -, in which at high concentrations tur

6. Evaluation of effects of acid deposition and iron particulate matter on physiological and reproductive process of restinga species / Avaliação dos efeitos causados pela deposição ácida e de ferro particulado sobre processos fisiológicos e reprodutivos em espécies de restinga
O bioma Mata Atlântica apresenta diferentes formações vegetacionais. Entre elas encontra-se a Restinga que, além de pouco estudada encontra-se exposta aos efeitos da deposição ácida e de material sólido particulado de ferro (MSPFe) emitidos pela atividade das indústrias mineradoras de ferro localizadas em suas adjacências, principalmente no litoral

7. Aspectos hidrogeoquímicos de uma microbacia reflorestada com Eucalyptus grandis no município de Angatuba - São Paulo / Hydrogeochemistry aspects of a Eucalyptus grandis reforested watershed in Angatuba - São Paulo
This study aimed to characterize the Entre Rios stream small watershed hydrogeochemistry, reforested with eucalyptus using materials transport models in dissolved and particulate phases, in periods of sampling, before and after the clearcutting. In the experimental area were collected river water samples, suspended particulate material, rain water, soil and

8. Composição elementar do material particulado presente no aerossol atmosférico do município de Sete Lagoas, Minas Gerais
The main objective of this study was the identification of sources generating particulate matter in the atmospheric aerosols of Sete Lagoas, Minas Gerais. The measurement of the mineral composition was accomplished by X-ray diffractometry and the elemental concentration by neutron activation analysis. The results showed that Al, Cl, Cu, Fe, K, Mg and Na are

9. Iron ore industry emissions as ecological risk factors for plant species of Anchieta restinga, Espírito Santo, Brazil / Emissões da indústria de minério de ferro como fatores de risco ecológico em espécies ocorrentes na restinga de Anchieta, Espírito Santo, Brasil
The restinga vegetation of the Espírito Santo state coast is exposed to the pollutants emitted by iron ore industry, the iron ore solid particulate matter and the wet acid deposition. To investigate the possible effects of these pollutants on the vegetation, biochemical, physiological, and ecological processes were evaluated. For that matter five native spe

10. Exposição aguda ao material particulado total em suspensão proveniente de diferentes fontes e suas repercussões nas respostas inflamatórias, sistêmica e local, em ratos / Acute exposure to total suspended particles from different sources and their impacts on both systemic and local inflammatory responses in rats
Background: Air pollution is associated with both increased morbidity and mortality. These associations persist even at lower concentrations and shortterm exposure. Objectives: To assess the impact of the components of three different sources of Total Suspended Particles (TSP) on local and systemic inflammatory responses in healthy rats. Methods: TSP from au

11. The role of fine particulate matter composition of PM2,5 and ROFA in the cell mutagenic potential and toxicity: a vegetable and animal bioassay study / Efeito da composição do material particulado fino, PM2,5 e residual oil fly ash (ROFA), como determinante do potencial mutagênico e tóxico celular: um estudo em bioensaios vegetais e animais
The association between atmospheric particulate matter (PM) and adverse human health effects have been consistently reported in epidemiological and experimental studies however, the ability to define the most important components involved in PM toxicity is hindered by its complex composition. In the present study we decided to further explore the effects of

12. Efeitos fisiológicos e bioquímicos causados pela deposição de ferro particulado em Clusia hilariana, uma espécie de restinga / Physiological and biochemical effects of iron ore dust in Clusia hilariana, a plant of restinga
Clusia hilariana, a CAM plant with crucial ecological role, has a broad distribution in brazilian restingas. With the aim to evaluate the physiological and biochemical effects of iron ore particulate matter (MSPFe), deposited in different fashions, on this species, three distinct experiments were carried out. Young plants were hydroponic cultivated in Hoagla
