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.

Journal of Animal Science, 1995
Increasing atmospheric concentrations of methane have led scientists to examine its sources of origin. Ruminant livestock can produce 250 to 500 L of methane per day. This level of production results in estimates of the contribution by cattle to global warming that may occur in the next 50 to 100 yr to be a little less than 2%.

Total methane emission rates and losses from 23 biogas plants.
Waste Management, 2019Methane losses from biogas plants are problematic, since they contribute to global warming and thus reduce the environmental benefits of biogas production.

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 Emissions and Ruminants
Microbe Magazine, 2009It was with great interest that I discovered the recent article entitled “Metabolic Teamwork between Gut Microbes and Hosts” in the July 2009 issue of Microbe (p. 323). Microbiologists, like myself, who work with gastrointestinal tract anaerobes are always interested in seeing this area of science highlighted in publications such as Microbe. Thanks for

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.

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.

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 ...

Methane emissions from natural wetlands
Environmental Monitoring and Assessment, 1996Methane is considered one of the most important greenhouse gases in the atmosphere. Because of the strict anaerobic conditions required by CH4-generating microorganisms, natural wetland ecosystems are one of the main sources of biogenic CH4. The total natural wetland area is estimated to be 5.3 to 5.7 × 10(12) m(2), making up less than 5% of the Earth ...
