“…It is noteworthy to mention that the GHG concentrations became remarkable over the common MSW transportation route of all provinces, starting after the junction crossing the routes 80 and 615 (404337 UTM Easting and 2910111 UTM Northing) and ending at the landfill site. The ground-level atmospheric distributions of GHG concentrations estimated in this study were in good agreement with those reported for urban districts using the similar methodology (Çetinkaya et al, 2018; Wen et al, 2017).…”

Greenhouse gas emissions resulting from municipal solid waste management activities and the associated climate change impacts are getting great attention worldwide. This study investigates greenhouse gas emissions and their distribution during waste collection and transport activities in the Dammam region of Saudi Arabia. Greenhouse gas emissions and associated global warming factors were estimated based on diesel fuel consumption during waste collection and transport activities. Then, waste collection and transport data were used to parameterise a mechanistic collection model that can be used to estimate and predict future fuel consumption and greenhouse gas emissions. For the collection and transport of municipal waste in the study area, the average associated total greenhouse gas emissions were about 24,935 tCO2-eq. Global warming factors for three provinces were estimated as 25.23 kg CO2-eq t-1, 25.04 kg CO2-eq t-1, and 37.15 kg CO2-eq t-1, respectively. Lastly, the American Meteorological Society/Environmental Protection Agency Regulatory Model (AERMOD) modelling system was used to estimate the atmospheric dispersion of greenhouse gas emissions. Model results revealed that the maximum daily greenhouse gas concentrations ranged between 0.174 and 97.3 mg m-3, while annual average greenhouse gas concentrations were found to be between 0.012 and 27.7 mg m-3 within the study domain. The highest greenhouse gas concentrations were observed for the regions involving the municipal solid waste collection routes owing to their higher source emission rates.

“…Traffic volume also plays an important role in creating CO pollution (USEPA, 2014;Pan et al, 2016;Wen et al, 2017;Le et al, 2021;Wang et al, 2021). Increased traffic volume generally leads to higher emissions (Pan et al, 2016;USEPA, 2014).…”

The traffic-related carbon monoxide (CO) pollution in Hillsborough County, Florida, has yet to be analyzed with high-resolution satellite data or algorithmic geo-spatiotemporal autocorrelation methods. This study aims to detect the association between traffic volume and CO pollution in Hillsborough County in 2022. It is hypothesized that daytime outdoor CO pollution positively correlates with traffic volume. High-resolution daily Giovanni remote sensing data of 1-degree spatial resolution from NASA Goddard Earth Sciences Data and Information Services Center was used to detect CO concentration on the roadways with annual average daily traffic (AADT) volumes larger than or equal to 80,000 in Hillsborough County. The results of AADT and CO concentrations indicated a clustering tendency. The Moran's Indices (I) of AADT was 0.956, and CO was 0.973. The results revealed a non-homoscedastic distribution of both AADT and CO concentrations. The performance of continuous data of CO and AADT was assessed by Pearson's correlation (r) to identify the strength and direction of CO concentration and AADT values. The results revealed a significant correlation between AADT and CO concentrations in this study with r=-0.119. The results also revealed an inversely proportional relationship; as AADT increased, daytime CO concentrations decreased. The clustered AADT and CO concentrations may account for biases in the correlation.

“…Tendo em vista que os veículos são fontes importantes de poluição do ar, compreender a magnitude da poluição à qual os humanos estão expostos é importante para determinar o efeito das emissões veiculares na qualidade do ar próximo às avenidas e rodovias (WEN et al, 2017). Com base nas afirmações acima, este trabalho tem como objetivo analisar a dispersão do material particulado inalável de até 10 micrômetros de diâmetro (MP 10 ), proveniente de caminhões pesados em uma avenida da cidade de São Paulo -SP (Av.…”

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.
