Geologic emissions of methane to the atmosphere
Chemosphere, 2002The atmospheric methane budget is commonly defined assuming that major sources derive from the biosphere (wetlands, rice paddies, animals, termites) and that fossil, radiocarbon-free CH4 emission is due to and mediated by anthropogenic activity (natural gas production and distribution, and coal mining).

A physico-chemical model to describe methane and carbon dioxide emission from lakes was developed. The model describes the emission by diffusion, bubbles and plants. The intensity of the fluxes can be calculated either for total or particular emission in dependence on gas bubbles composition.

Methane emissions from wastewater management
Environmental Pollution, 2001Greenhouse gas emissions in the form of methane and carbon dioxide are produced when municipal and industrial wastewater and their residual solid by-product (sludge) are handled under or subject to anaerobic conditions, thus contributing to the global warming potential or the greenhouse effect.

Methane Emission of the Amsterdam Urban Area
Water, Air, and Soil Pollution, 1998Within the Dutch National Research Programme on Climate Change, the emission of methane from urban areas was considered to be one of the uncertain sources in the national methane budget. Amsterdam was chosen to be a representative urban area for methane emission assessment.

Measurement and prediction of enteric methane emission
International Journal of Biometeorology, 2010The greenhouse gas (GHG) emissions from the agricultural sector account for about 25.5% of total global anthropogenic emission. While CO(2) receives the most attention as a factor relative to global warming, CH(4), N(2)O and chlorofluorocarbons (CFCs) also cause significant radiative forcing.

The atmospheric concentration of methane has increased rapidly in recent years. Because it is a radiative trace gas and takes part in atmospheric chemistry, the rapid increase could be of significant environmental consequence. Of the wide variety of sources, rice fields are considered an important source of atmospheric methane because the harvest area ...

Scaling methane emissions from vegetation
Trends in Ecology & Evolution, 2006In a recent highly publicised paper, Keppler et al. [1] report the remarkable observation that methane is emitted directly by plants, and in an aerobic environment. Previously, emissions from vegetation were attributed to anaerobic microbial associations (e.g. in water-logged soils).

Methane emissions from MBT landfills
Waste Management, 2013Within the scope of an investigation for the German Federal Environment Agency ("Umweltbundesamt"), the basics for the estimation of the methane emissions from the landfilling of mechanically and biologically treated waste (MBT) were developed. For this purpose, topical research including monitoring results regarding the gas balance at MBT landfills ...

Methane and nitrous oxide emissions: an introduction
Fertilizer Research, 1994Methane and nitrous oxide are important greenhouse gases. They contribute to global warming. To a large extent, emissions of methane and nitrous oxide are connected with the intensification of food production. Therefore, feeding a growing world population and at the same time controlling these emissions is a great challenge.
