[pt] AVALIAÇÃO DA QUALIDADE DO AR NO RÉVEILLON EM COPACABANA, RIO DE JANEIRO / [en] NEW YEAR S AIR QUALITY ASSESSMENT IN COPACABANA, RIO DE JANEIRO

ANA CAROLINA DE OLIVEIRA CARVALHO 18 October 2022 (has links)
[pt] O Réveillon em Copacabana, no Rio de Janeiro, na virada do dia 31/12 para o dia 01/01, ocorre com a queima de 17 a 25 t de fogos de artifícios com duração entre 12 a 17 minutos. Estudos realizados em outros países durante comemorações com queima de fogos mostram um aumento significativo de alguns poluentes no ar. Este estudo avaliou a qualidade do ar em Copacabana durante as comemorações do ano novo de 2015 a 2020, considerando as concentrações do MP10, SO2, CO e O3 amostrados na estação automática. Pelo teste de Shapiro-Wilk, uma distribuição assimétrica no banco de dados foi observada, e através do teste não paramétrico as concentrações diárias entre os dias 31 de dezembro e 01 de janeiro foram testadas. A composição química MP2,5 amostrado na estação semiautomática de Copacabana em 2019, foi realizada através das técnicas analíticas de cromatografia de íons (CI) e espectrometria de massa por plasma acoplado indutivamente (ICP-MS), traduzido do inglês, inductively coupled plasma mass spectrometry. Durante o ano de 2019, as concentrações diária e anual do MP(2,5) não ultrapassaram os padrões nacionais de qualidade do ar, mas segundo os padrões recomendados pela OMS, a qualidade do ar esteve inapropriada. As concentrações elementares e iônicas determinadas por ICP-MS e CI indicaram espécies características de fontes veiculares e naturais. Em 01 de janeiro de 2020 a concentração dos íons Cl(-) e Na(+), foi atribuída ao spray marinho, e a ausência dos ânions C2H3COO(-), CH2(COO)2(2-) CHOO(-) e C2O4(2-) foi atribuída à diminuição da circulação urbana. / [en] New Year s Eve in Copacabana, Rio de Janeiro, at the turn of 12/31 to 01/01, takes place with the burning of 17 to 25 t of fireworks lasting between 12 and 17 minutes. Studies carried out in other countries during celebrations with fireworks show a significant increase in some pollutants in the air. This study evaluated the air quality in Copacabana during the New Year celebrations from 2015 to 2020, considering the concentrations of PM10, SO2, CO and O3 sampled at the automatic station. By the Shapiro-Wilk test, an asymmetry distribution in the database was observed, and through the non-parametric test the daily concentrations between December 31st and January 1st were tested. The chemical composition PM2.5 sampled at the semi-automatic station in Copacabana in 2019 was performed using analytical techniques of ion chromatography (IC) and inductively coupled plasma mass spectrometry (ICP-MS). During the year 2019 concentrations of PM2.5 not exceeded to national air quality standards, but according to the standards recommended by the WHO, the air quality was inappropriate. The elemental and ionic concentrations determined by ICP-MS and CI indicated species characterized from vehicular and natural sources. On January 1, 2020, the concentration ions of Cl(-)and Na(+) was attributed to marine spray, and the absence of the anions C2H3COO(-), CH2(COO)2(2-) CHOO(-) e C2O4(2-) was attributed to the lowest urban circulation.
