“…A 10-year analysis in the MASP showed that an increase of 10 µg m −3 in the concentration of PM 10 causes an increase in the relative risk of death from respiratory diseases in the elderly (Pinheiro et al, 2014). Recently, Segalin et al (2016) characterised the mass of size-segregated PM in elderly residences in the MASP and found, for example, that the indoor concentrations of PM 2.5 and PM 10 were higher than the outdoor concentrations in approximately 77% and 40%, respectively, of those residences.…”

“…The elderly and the children are more susceptible to the health effects resulting from PM 2.5 (Cançado et al, 2006;Segalin et al, 2017). Considering that the elderly population has grown in São Paulo over the last decades (SEADE, 2016;Segalin et al, 2017), the PM health-related issues can become more relevant. PM also plays an important role in ecosystem biogeochemistry, the hydrological cycle, cloud formation and atmospheric circulation (Pöschl, 2005).…”

“…In this context, PM 2.5 (PM with an aerodynamic diameter smaller than 2.5 µm) and PM 10 (PM with an aerodynamic diameter smaller than 10 µm) are particles that are able to penetrate the respiratory system, with PM 2.5 reaching alveoli in the lungs, and induce adverse impacts on human health (Cai et al, 2015;Kumar et al, 2014). The elderly and the children are more susceptible to the health effects resulting from PM 2.5 (Cançado et al, 2006;Segalin et al, 2017).

Abstract. São Paulo in Brazil has relatively relaxed regulations for ambient air pollution standards and often experiences high air pollution levels due to emissions of particulate pollutants from local sources and long-range transport of air masses impacted by biomass burning. In order to evaluate the sources of particulate air pollution and related health risks, a year-round sampling was done at the University of São Paulo campus (20 m a.g.l.), a green area near an important expressway. The sampling was performed for PM 2.5 (≤ 2.5 µm) and PM 10 (≤ 10 µm) in 2014 through intensive (everyday sampling in wintertime) and extensive campaigns (once a week for the whole year) with 24 h of sampling. This year was characterized by having lower average precipitation compared to meteorological data, and high-pollution episodes were observed all year round, with a significant increase in pollution level in the intensive campaign, which was performed during wintertime. Different chemical constituents, such as carbonaceous species, polycyclic aromatic hydrocarbons (PAHs) and derivatives, water-soluble ions, and biomass burning tracers were identified in order to evaluate health risks and to apportion sources. The species such as PAHs, inorganic and organic ions, and monosaccharides were determined using chromatographic techniques and carbonaceous species using thermal-optical analysis. Trace elements were determined using inductively coupled plasma mass spectrometry. The risks associated with particulate matter exposure based on PAH concentrations were also assessed, along with indexes such as the benzo[a]pyrene equivalent (BaPE) and lung cancer risk (LCR). High BaPE and LCR were observed in most of the samples, rising to critical values in the wintertime. Also, biomass burning tracers and PAHs were higher in this season, while secondarily formed ions presented low variation throughout the year. Meanwhile, vehicular tracer species were also higher in the intensive campaign, suggesting the influence of lower dispersion conditions in that period. Source apportionment was performed using positive matrix factorization (PMF), which indicated five different factors: road dust, industrial emissions, vehicuPublished by Copernicus Publications on behalf of the European Geosciences Union. 11944 G.

The results highlighted the contribution of vehicular emissions and the significant input from biomass combustion in wintertime, suggesting that most of the particulate matter is due to local sources, in addition to the influence of pre-harvest sugarcane burning.

ENVIRONMENTAL CHEMISTRY IN BRAZIL IN 40 YEARS IN THE SBQ. This paper aims to present an overview of the ongoing of the Brazilian environmental chemistry over the last forty years inserted in the context of the Brazilian Chemical Society (SBQ). Initially, a brief history presents the main milestones and premise of its "birth" in the 1980s, as well as the set of major actions taken within the SBQ to consolidate and strengthen this area of research. Then, in a separated approach between atmosphere, hydrosphere and lithosphere, we present the evolution of the main topics covered in Environmental Chemistry in Brazil, as well as the contribution of the chemists in the interdisciplinary scenario that constitutes this area. Finally, an overview of the evolution of the teaching of Environmental Chemistry in Brazil is presented.Keywords: environmental chemistry, atmosphere, hydrosphere, lithosphere, HISTÓRICO DA QUÍMICA AMBIENTAL NO BRASILNo Brasil, a Química Ambiental se desenvolveu a partir de um vínculo estreito com a Química Analítica, que se consolidou com base em uma escola consolidada e tradicional, com uma visão clássica sobre seu papel e voltada, em primeira instância, para o desenvolvimento de protocolos analíticos e elucidação de problemas estabelecidos dentro do laboratório. Portanto, boa parte dos primeiros químicos ambientais tinha uma forte ligação com a Química Analítica e eram poucos aqueles com experiência em trabalhos de campo e amostragem ambiental. Nos anos 1980, a pesquisa em Química Ambiental conduzida em nosso país tinha como base o monitoramento de espécies químicas presentes na hidrosfera, atmosfera e biota.1 Existem documentos evidenciando a escassez de atividades de pesquisa dedicadas ao estudo da reatividade química e comportamento de poluentes não apenas nos três compartimentos mencionados anteriormente, mas igualmente em suas interfaces.2 Estas circunstâncias resultaram em um desenvolvimento mais lento da Química Ambiental brasileira, quando comparada com a de outros países, especialmente os desenvolvidos. Não obstante estes aspectos, nos dias atuais a Química Ambiental ocupa posição de destaque no cenário científico nacional, tendo igualmente alcançado projeção internacional. Vários eventos científicos também têm contribuído para isso, tais como as Reuniões Anuais da Sociedade Brasileira CENÁRIO DE ESTUDO DA QUÍMICA AMBIENTAL NO BRASILPara contemplar o cenário das pesquisas em Química Ambiental no Brasil, decidimos dividir os estudos em hidrosfera, atmosfera e litosfera, embora estes compartimentos sejam integrados e não haja um mais importante que o outro e tampouco podem ser vistos separadamente. Além disso, este texto não tem a pretensão de fazer uma revisão exaustiva das publicações nestas áreas dentro da Química Ambiental, mas sim de apresentar um panorama da evolução e dos temas que foram e estão sendo estudados nestes 40 anos da Sociedade Brasileira de Química, apresentando exemplos de alguns destes trabalhos.
