“…In Bangu station, neighborhood Deodoro region was observed by Silva et al (2016) the highest ozone concentrations and the largest number of air quality standard exceedances in Rio de Janeiro city in 2012 and 2013. According to Tsuruta et al (2017), it is justified because this region is characterized by higher temperatures and poor air circulation in comparison to the other regions of the city. Geraldino et al (2017), who also studied Bangu, concluded that the mountains in the southern and northern part of the west region contribute to the increase of surface temperature and the accumulation of local and transported pollutants.…”

For the accomplishment of Olympic and Paralympic Games in Rio de Janeiro city (Rio 2016), the government of the Rio de Janeiro state has undertaken to monitor air quality before and during the events. In Beijing, China, and Athens, Greece, the air quality was monitored in Olympic venues in order to evaluate the athletes' performance in relation to the environment in which they were exposed. This study has the same proposal to Rio de Janeiro, Brazil. The air quality scenario of the three previous years (2013, 2014, 2015) of Rio 2016 was considered. Coarse (PM10) and fine (PM2.5) particles and O3 were monitored continuously on the stations located near to competition venues, as required by International Olympic Committee (IOC). The levels registered ranged from 6 to 96 μg m-3 for PM10, 1 to 44 μg m-3 for PM2.5 and 121 to 269 μg m-3 for O3. These concentrations exceeded the national and international air quality standards. These high concentrations are associated with uncountable civil works to build Olympic arenas and the urban mobility´s improvement. however, the concentrations for all the pollutants monitored in Rio de Janeiro city were in lower concentrations than in Beijing Olympic Games 2008.

“…18,20 Os parâmetros meteorológicos (temperatura, umidade, radiação solar, precipitação, direção e velocidade do vento) e a concentrações dos poluentes legislados (CO, NO 2 , e O 3 ) foram fornecidos pela estação de monitoramento da qualidade do ar da SMAC. 21 Os Índices de Qualidade do Ar (IQA), [22][23][24] calculados pela SMAC, foram obtidos na homepage da SMAC. 21 É importante mencionar que para realizar um estudo de simulação devem ser fornecidos dados, no mínimo, de médias horárias de temperatura, umidade e concentrações de CO, NO, NO 2 e O 3 para serem utilizados em combinação com as concentrações e especiação de COVs.…”

“…As concentrações de ozônio no período 15 de maio a 15 de junho foram menores que no mês de março, no qual houve, inclusive, algumas ultrapassagens ao padrão primário de qualidade do ar de 160 µg m -3 , configurando um IQA com classificação Inadequada. [21][22][23][24] Já no período seco foram observadas concentrações maiores de NO 2 e CO em muitos horários, como é geralmente encontrado para poluentes primários. Da mesma forma, as concentrações totais de COVs determinadas nas duas campanhas são muito diferentes, com valores aproximadamente o dobro para a campanha 02.…”

Atmospheric processes in an urban scenario are very complex and depend on meteorological parameters, emission, transport and deposition processes and the chemical mechanism. Simple air quality models can be used to understand the main aspects of ozone formation and provide information to adopt pollution control strategies. In this work the detailed simulation of ozone concentrations using the air quality model OZIPR (Ozone Isopleth Package for Research) coupled with the SAPRC (Statewide Air Pollution Research Center) chemical model is presented. First, the methods to determine volatile organic compounds (VOCs) are described as well as the statistical treatment of experimental data: Meteorological parameters (temperature, humidity, pressure, wind speed and direction), concentrations of nitrogen oxides (NO x = NO 2 + NO), carbon monoxide (CO) and ozone (O 3), which are needed to characterize the problem. Then, the construction and adjust of the model (base case) is detailed using, as an example, data for a typical urban area in the city of Rio de Janeiro. Finally, the limitations and the potential of the model are discussed. Clearly the quality of experimental data, mainly NO x and COVs concentrations and the COVs speciation, are a key information to obtain a correct estimation of O 3 levels.

“…Air quality indexes (AQIs) determined in Rio de Janeiro from July-September 2016, before and during the Summer Olympic and Paralympic Games, by monitoring stations operated by the SMAC, were compiled and analyzed by Tsuruta et al 23 NO 2 and PM 10 levels were generally lower during the Olympic period because of restrictions on vehicular flux. However, ozone concentrations remained high, 23 and a further study seems necessary to analyze the concentrations of ozone precursors and unfavorable meteorological conditions.…”

The air quality during the Summer 2016 Olympic Games in two Olympic zones, Maracanã (Tijuca) and Deodoro, was studied. Volatile organic compounds (VOCs) were collected and analyzed following method TO-15 (United States Environmental Protection Agency), during and in the days after the Games. The total VOC (C 4 -C 12 ) concentrations were 39.2-160.9 and 36.6-191.4 µg m -3 for Tijuca and Deodoro, respectively. These concentrations were lower than values previously obtained in Tijuca and other areas of the city. VOC speciation and benzene/ toluene ratios were also different as a consequence of the restrictions imposed on vehicular transit during the Olympic Games. Concentrations were discussed considering the reactivity and ozone forming potential of individual compounds. Criteria pollutants, determined by the Tijuca Automatic Monitoring Station, were also analyzed. The preventive policies were successful in decreasing the concentrations of CO and PM 10 , leading to a decrease in mean ozone levels. However, air quality indexes were not dramatically reduced, because of the increase in NO x emissions and isolated events of higher ozone levels.
