1. Capacited Vehicle Routing Problem with CO2 Emission Minimization Considering Path Slopes
ABSTRACT This work presents the application of a CO2 emission estimation function for cargo vehicles on a Capacited Vehicle Routing Problems (CVRP) setting, considering route’s slopes variation. Comparisons were established with functions minimizing fuel consumption and route length in a case study about selective collection of recyclable waste at Sorocaba

2. Nitrogen Oxides Levels in the Atmosphere of Different Brazilian Urban Centers, by Passive Sampling
Urban air pollution is still an emerging environmental problem, it causes damage to health and is difficult to be controlled in urban centers. The population of large metropolises is often exposed to concentrations of nitrogen oxides (NOx), mainly due to vehicle emissions. Epidemiological studies claim that exposure to these oxides is strongly correlated wit

3. PREPARAÇÃO E VALIDAÇÃO DE ARQUIVOS DE ENTRADA PARA USO NO SIMULADOR DE QUALIDADE DO AR (CMAQ)
According to the inventories carried out by the air pollution control agencies, vehicle emissions are responsible for more than 70% of air pollutants in metropolitan regions. Proper handling of CMAQ input data is an important step in the formation of a database for the model. Thus, it is necessary to insert the meteorological data using the Weather Research

4. Fatores de emissão de compostos carbonílicos medidos em um túnel do Rio de Janeiro, Brasil, em condições reais de dirigibilidade
Real-world vehicle emissions of carbonyls compounds (CC) were determined at the Rebouças Tunnel, Rio de Janeiro (Brazil). The tunnel is a two-bore tunnel with three lanes in each direction and has a length of 2840 m, divided in two sections. On average, approximately 5,000 vehicles (95% light duty) were passing the tunnel per hour. Sixteen samples were simu

5. Balanço de carbono em cidades da Amazônia: estudo de caso em Belém, Brasil
Resumo O município de Belém, no Pará, tem apresentado crescimento contínuo de sua área urbanizada e da frota de veículos nas últimas décadas. Essas mudanças estão também associadas a reduções na área de cobertura vegetal e ao aumento das emissões de CO2 locais. Há, portanto, a necessidade de se entender, de maneira integrada, a dinâmica das

6. Analysis of the Impacts of the Electrification of the Vehicle Fleet in the Electric Power System in Curitiba
ABSTRACT The Market share of electrical vehicles has been rising in the past few years and tends to rise even more. According to the International Energy Agency, an increase of 50% in the number of electrical vehicles is expected. Whilst that increase is beneficial from a greenhouse gases emissions drop point of view, that rise could, on the other hand, repr

7. Estimated evolution of total pollutant gas emissions associated with vehicle activity in the Metropolitan Region of Porto Alegre until 2030
ABSTRACT In recent years, the majority of economic sectors in Brazil have gone through processes of development and transformation. These processes have led to increases in environmental pollution of all kinds; air pollution being one of the most adverse. The Brazilian transportation sector, which heavily affects the air quality, experienced a significant in

8. Potencial uso de serpentinito no armazenamento mineral do CO2
Rising anthropogenic CO2 emissions are considered a major contributor to the greenhouse effect. There are several options for reducing atmospheric CO2 levels, and among these alternatives, Carbon Capture and Storage (CCS) has been identified as an effective and promising approach. This work investigated the feasibility of using serpentinite as a vehicle for

9. Elementos traço em material particulado atmosférico de uma região agroindustrial do sudeste do Brasil
Trace element concentrations were measured in atmospheric particulate matter collected in 2009 and 2010, in a Brazilian region influenced by pre-harvest burning of sugar cane crops. For coarse particles, high concentrations of Al, Fe, K and Ca suggested that re-suspended soil dust was the main source of aerosol trace elements, subsequently confirmed by XRD a

10. Avaliação do ciclo de vida da areia em mineradora de pequeno porte, na região de São José do Rio Preto - SP / Life Cycle Assessment of sand in small mining in São José do Rio Preto region - São Paulo.
The mining of sand, although of great socio-economic importance to the national scene, has several negative impacts throughout the production chain. Among some of the interference in the natural environment occurs, soil degradation, air pollution and stress in the fauna and flora. This fact has generated great interest in mechanisms that mitigate or prevent

11. Determinação de compostos monoaromáticos voláteis provenientes de emissões de veículos leves, em estacionamentos subterrâneos. / Determination of volatile monoaromatic compounds emissions from light vehicles in underground parking lots.
This study aims to determine the contribution of evaporative emissions from light passenger vehicles to the degradation of the air quality. The main objective is to evaluate the concentrations volatile monoaromatic compounds benzene, toluene, ethylbenzene and xylenes (BTEX) indoors, in a site that represents the reality of the vehicular fleet of the Metropol

12. Composição química da precipitação úmida da região metropolitana de Porto Alegre, Brasil, 2005- 2007
This work aims to quantify the wet precipitation the Metropolitan Area of Porto Alegre (MAPA), in southern Brazil, through the analysis of major ions (by ion chromatography) and metallic elements (ICP/AES). By principal components analysis and cluster analysis was possible to identify the influence of natural and anthropic sources in wet precipitation. The r
