Aspectos do papel do peróxido de hidrogênio como oxidante na atmosfera no contexto das atuais políticas públicas de emissões veiculares

Abstract: A Deus, por me dar forças e iluminar o meu caminho, estando sempre ao meu lado. Aos meus pais, João Carlos e Cristina, pelo amor, paciência e confiança que me ofereceram durante toda a minha vida. Ao meu irmão João Vitor, por ser meu companheiro e meu grande orgulho. Ao Éric, pelo amor e carinho, e por ter me dado todo o suporte, não só emocional, como também físico, me acompanhando nas pesquisas de campo, que muitas vezes se tornaram aventuras. À minha madrinha tia Márcia e ao Erivelto, por terem me acolhido … Show more

“…where average concentrations were 35.0±14.0 ppb and 1.35±0.40 ppm for ethanol and CO, respectively. In addition, the average concentrations observed during our campaigns were higher than those measured in other studies in MASP (Brito et al, 2018;Scaramboni, 2018). This fact could be related to the distance to the emission sources and other external factors such as ethanol consumption and usage, atmospheric and meteorological conditions, and differences on the measurement techniques used.…”

“…Few short-term ethanol measurements were performed in SPM during the last two decades, which applied a wide range of measurement techniques at different sampling sites (traffic, road tunnels, urban background and background). Ambient ethanol concentrations observed at SPM were quite dissimilar, reaching between 18 to 460 ppb (Pereira et al, 1999;Schilling et al, 1999;Colón et al, 2001;Nguyen et al, 2001;Alvim, 2013;Brito et al, 2018;Scaramboni, 2018). Hence, in view of the high uncertainties surrounding the global and regional emission estimations, specifically for VOCs, there is an urgent need for the assessment of their emissions.…”

“…The behavior of ethanol is similar in certain months only. The concentrations of ambient ethanol observed in other researches carried out in SPMA were quite different, reaching between 18 and 460 ppb, in this study an annual average of 36 ppb was found (Schilling et al, 1999;Colón et al, 2001;Nguyen et al, 2001;Brito et al, 2018;Scaramboni, 2018). In cities where ethanol is used as fuel additive, for example in Los Angeles and London, increased levels on an average of 5 ppb and 9 ± 5 ppb respectively were observed (de Gouw et al, 2012;Dunmore et al, 2016).…”

“…Few short-term ethanol measurements have been made at the SPMA over the past two decades, which have applied a wider range of measurement techniques at different locations sampling methods (traffic, road tunnels, urban and environment). The concentrations of ambient ethanol observed in the SPMA were quite different, reaching between 18 and 460 ppb (Schilling et al, 1999;Colón et al, 2001;Nguyen, 2001;Scaramboni, 2018;Brito et al, 2018). Therefore, in view of the high uncertainties surrounding global and regional emissions estimates, specifically for VOCs, there is an urgent need to measure your concentrations as realized in this study to perform more accurate emissions calculations.…”

“…As amostras coletadas em 2019 em Ribeirão Preto apresentaram concentrações semelhantes às relatadas por Scaramboni (2018), coletadas no mesmo sitio amostral, que relatou médias de 13,7 ± 7,5 ppbv de etanol e 16,6 ± 7,8 ppbv de acetaldeído (n = 10). Os resultados obtidos em 2020, se tratam de coletas realizadas após 103 dias de estiagem, com umidade relativa do ar durante vários dias atingindo cerca de 13-15%, o que inviabilizou as análises em replicatas, devido ao baixo volume de condensado produzido.…”
