| description | The Brazilian transport system is based on the use of highways and heavy-duty trucks are the main vehicles used to transport goods, responsible for 70% of vehicular particulate matter (PM10) emissions in the State of São Paulo. Therefore, the search for alternative technologies to reduce emissions from the transport sector is increasing. Considering the importance of reducing pollutants emissions and the air quality improvement in large urban centers, this research aims to calculate and evaluate the particulate matter (PM10) emissions from heavy-duty trucks on an avenue (Avenida Marginal Tietê) in the city of São Paulo. For this, the atmospheric dispersion model AERMOD was used to calculate the average PM10 concentrations emitted by heavy-duty trucks powered by diesel, and the impacts derived from the replacement of 100% of this fuel by liquefied natural gas (LNG) was evaluated. Results show that the automotive technology replacement helps to reduce 99% of PM10 by the analyzed avenue, but further studies are needed to assess the total concentration and other possible impacts, such as effects on human health resulting from exposure to this pollutant on this avenue. |

O sistema de transporte brasileiro baseia-se no modo rodoviário, sendo os caminhões o principal veículo utilizado no transporte de mercadorias, responsável por 70% das emissões de material particulado (MP) veiculares do Estado de São Paulo. Por isso, é cada vez maior a busca por tecnologias alternativas para reduzir as emissões do setor de transportes. Tendo em vista a necessidade de reduzir poluentes e melhorar a qualidade do ar em grandes centros urbanos, o objetivo dessa pesquisa é calcular e analisar as emissões de material particulado com diâmetro de até 10μm (MP10) provenientes de veículos de carga rodoviários na Avenida Marginal Tietê, na cidade de São Paulo. O presente trabalho faz uso do modelo de dispersão atmosférica AERMOD para calcular as concentrações médias desse poluente, decorrentes da emissão dos caminhões movidos a Diesel, e os impactos da substituição de 100% deste combustível pelo gás natural liquefeito (GNL). Os resultados mostram que a substituição tecnológica auxilia na redução de 99% das emissões de MP10 ao longo do trecho da Avenida analisado, mas são necessários outros estudos para avaliar a concentração total e outros possíveis impactos, como os efeitos na saúde da população decorrentes da exposição desse poluente nessa via. 2021-12-12 2022-03-17T15:14:53Z 2022-03-17T15:14:53Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://www.revistas.usp.br/rdg/article/view/185828 10.11606/eISSN.2236-2878.rdg.2021.185828 http://biblioteca-repositorio.clacso.edu.ar/handle/CLACSO/42412 por https://www.revistas.usp.br/rdg/article/view/185828/178210 Copyright (c) 2021 Raquel Rocha Borges, Ana Carolina Rodrigues Teixeira, Dominique Mouette, Flávia Noronha Dutra Ribeiro https://creativecommons.org/licenses/by-nc-sa/4.0/ application/pdf Universidade de São Paulo.
