1. The Contribution of Meteorological Parameters and the COVID-19 Partial Lockdown on Air Quality in Rio de Janeiro, Brazil
This study evaluated the pollutant levels (NO2, SO2, CO, and O3), air quality index (AQI) and the influence of meteorological variables and coronavirus disease (COVID-19) pandemic on the air quality in Rio de Janeiro. The data set used comprises periods before (March-April, 2019) and during pandemic (March-April, 2020). According to the AQI results, on most

3. Estructura, composición florística y almacenamiento de carbono en bosques nativos del páramo de Anaime, Tolima, Colombia
Abstract Páramos have a high environmental importance due to their high plant and animal endemism, water regulation and carbon storage. In this work, the structure and composition of the tree vegetation were characterized as well as carbon storage in aboveground biomass and the potential reduction of emissions by deforestation were estimated prioritizing th

4. Changes in the microbial community during bioremediation of gasoline-contaminated soil
Abstract We aimed to verify the changes in the microbial community during bioremediation of gasoline-contaminated soil. Microbial inoculants were produced from successive additions of gasoline to municipal solid waste compost (MSWC) previously fertilized with nitrogen-phosphorous. To obtain Inoculant A, fertilized MSWC was amended with gasoline every 3 days

5. POTENTIAL OF REDUCTION IN THE EMISSION OF METHANE AND NITROUS OXIDE FROM SWINE WASTEWATER AFTER TREATED BY TWO DIFFERENT SYSTEMS
ABSTRACT Swine wastewater have high pollution load, requiring treatment before its disposal into the environment. Methane (CH4) potentially emitted for such waste is considered 21 times more polluting than Carbon dioxide (CO2), and the nitrous oxide (N2O) is considered 310 times. In this way, projects of the Clean Development Mechanism (CDM) and energy use r

6. Synthesis and Mechanical Characterization of Iron Oxide Rich Sulfobelite Cements Prepared Using Bauxite Residue
The bauxite residue (BR) is the solid waste of largest generation by the aluminum industry, with a generation estimated in 10 million ton/year in Brazil. Its high alkalinity demands elevated costs to store it safely. Due to the high content of Al2O3 and Fe2O3 in BR, the present study evaluated its application for the synthesis of iron rich sulfobelite clinke

7. Filamentous fungi isolated from Brazilian semiarid tolerant to metallurgical industry wastes: an ex situ evaluation
The purpose of this study was to assess the impact of metallurgical industry wastes on the semiarid soil microbiota using physico-chemical and microbiological parameters, highlighting the filamentous fungi assembly. Soil samples were collected in an area of industrial waste deposit contaminated with lead and mixed with natural soil (control soil) in seven di

8. Catalytic oxidation of volatile organic compounds (n-hexane, benzene, toluene, o-xylene) promoted by cobalt catalysts supported on γ-Al2O3-CeO2
Cobalt catalysts supported on γ-alumina, ceria and γ-alumina-ceria, with 10 or 20%wt of cobalt load, prepared by the wet impregnation method and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), field emission transmission electron microscopy (FETEM), N2 adsorption-desorption isotherms (BET/BJH methods), energy-dispersive X-ray

9. Produção de gases de efeito estufa e potencial de geração de créditos de carbono em processos de tratamento de esgoto sanitário
The concept of carbon credits came from the awareness of need to reduce greenhouse gas (GHG) emissions in order to combat the worsening of global warming, discussed and formalized in the Kyoto Protocol. Emission of greenhouse gases as methane, nitrous oxide and carbon dioxide is due to several activities, among them the wastewater treatment, both domestic an

10. DESEMPENHO EM DINAMÔMETRO E EMISSÕES RESIDUAIS DE UM MOTOR DE TRATOR AGRÍCOLA OPERANDO COM MISTURAS BINÁRIAS DE ÓLEO DIESEL B5 E BIODIESEL DE ÓLEO DE FRANGO / PERFORMANCE IN DYNAMOMETER AND EMISSIONS OF WASTE AN AGRICULTURAL TRACTOR ENGINES OPERATING WITH BINARY MIXTURES B5 DIESEL AND BIODIESEL OIL CHICKEN
Brazil, the third largest producer of biodiesel in the world, and also the third largest producer of chicken, may increase in some regions, the use of oil derived from birds, as an alternative to fossil fuels. In order to increase the range of options to reduce dependence on soybean oil for that purpose, and fostering environmental aspects, it is possible to

11. Desenvolvimento sustentável na Amazônia: uma nova abordagem do dendê com o aproveitamento da biomassa residual para a geração de energia. / Sustainable development in the Amazon region: a new approach with the use of palm oil biomass waste to generate energy
This study examines the viability of a sustainable project with the production of palm (Elaeis guineensis) to supply oil to food or cosmetic industries and the use of the residual biomass as a biofuel by a power plant. The biofuel side of the project aims the provision of electricity in part of the so called Isolated System, in southern Roraima. The analysis

12. Medidas da emissão de poluentes e da eficiência na combustão assistida do glicerol residual de biodiesel. / Measurements of emissions and fuel efficiency of the assisted residual glycerol biodiesel.
With increased global production of biofuels in particular biodiesel, an excess of glycerol is being generated worldwide. This has caused a sharp drop in the price of this compound in the world market. Much thought has been given to a destination for this residue, since no one can lay it in the environment and one of the alternatives be to use would its calo
