1. Nitrous oxide emissions from an intermittent aeration activated sludge system of an urban wastewater treatment plant
This study investigated the emission of N2O during the sequential aerated (60-min) and non-aerated (30-min) stages of an intermittent aeration cycle in an activated sludge wastewater treatment plant (WWTP). N2O emission occurred during both stages; however, emission was much higher during aeration. Air stripping is the major factor controlling transfer of N2

2. Emissões de óxido nitroso do tanque de aeração de uma estação de tratamento de esgotos com sistema de lodos ativados convencional
Nitrous oxide (N2O) emissions were measured monthly from January to June 2010 in the aeration tank of a wastewater treatment plant (WWTP) in Southeast Brazil. Emissions were lower in summer than winter and were positively related with influent ammonium (NH4+) concentration. The average N2O emission was 1.11 kg N day-1 corresponding to 0.02% of the influent t

3. Produção de óxido nitroso de solo cultivado com feijoeiro comum irrigado em sistema plantio direto no cerrado / Production of nitrous oxide from soil cultivated with common bean in irrigated no tillage system in savanna (Cerrado)
A perda de nitrogênio no sistema solo-planta tem repercussões econômicas e ambientais, especialmente quando óxidos de nitrogênio são emitidos para a atmosfera. O objetivo deste estudo foi avaliar a emissão de óxido nitrosos (N2O) em sistema de produção de feijoeiro comum irrigado em sistema plantio direto, sobre palhada de braquiária, com aplicaç

4. EMISSION OF NITROUS OXIDE AND CARBON DIOXIDE AFTER APPLICATION OF PIG SLURRY AND CATTLE DEJECTIONS IN AN HAPLUDALF / EMISSÃO DE ÓXIDO NITROSO E DIÓXIDO DE CARBONO APÓS APLICAÇÃO DE DEJETOS DE SUÍNOS E BOVINOS EM UM ARGISSOLO
Emission of greenhouse effect gases due to the agricultural use of the dejections of animals as fertilizers, as well as the mineralization of the carbon of those materials in the soil healthy aspects are still relatively a little studied in Brazil. This work was accomplished to evaluate: 1) the annual emission of nitrous oxide with the use, in the corn, of m

5. Quantification of N2O emissions from fertilizer, N2 fixation and crop residues in an Udult soil. / Quantificação das emissões de N2O resultantes de fertilizante, fixação de N2 e resíduos de colheita em Argissolo Vermelho-Amarelo.
Nitrous oxide (N2O) is one of the gases responsible for the greenhouse effect, and soils are the main source of this gas to the atmosphere. The N availability in the soil is the main factor influencing their emissions. Thus, cropping systems that use nitrogen fertilizers, along with the decomposition of harvesting residues can enhance N2O emissions, exacerba

6. Newly Recognized Vital Nitrogen Cycle
Soil and sea bacteria produce a small amount of nitrous oxide (N2O); a small part of this N2O is photochemically converted to nitric oxide (NO) in the stratosphere. This process has recently been shown to be the principal source of the active oxides of nitrogen (NO and NO2) in the stratosphere. The active oxides of nitrogen catalytically destroy ozone, and N
