N 2O emission was negligible in the studied system; the only product of denitrification was N 2. Only 10% of total carbon emissions were in the form of CH 4. Amount of C emitted was higher than carbon input in the wastewater; it was calculated that between one fourth and one third of...
A special attention was paid to those sectors of industry that may be the first to act as a source of carbon dioxide for sequestration by underground storage in the nearest future. To cite this article: R. Tarkowski, C. R. Geoscience 337 (2005)....
Scenario analysis is employed to predict future carbon emission equivalents and to indicate possible implications for climate change mitigation in this sector. Carbon emissions from coal development are mainly derived from coal mine gas emissions, which yield 62% of the sector's total carbon emissions...
The first comprehensive study to investigate carbonaceous PM2.5 in Sanya, ChinaHigher carbonaceous levels in winter while more SOC formation in summerAnthropogenic emission is the dominant sources of n-alkanesVehicle emission and biomass burning contributed ≥60% of the total PAHs in winterThe result ...
Efforts to control climate change require the stabilization of atmospheric carbon dioxide concentrations. An assessment of the trends in sources and sinks of atmospheric carbon dioxide suggests that the sinks are not keeping up with the increase in carbo
However, the reality of such actions often carries numerous negative consequences. First of all, searching for energy in remote areas will simply increase the amount of energy required for transportation. Often referred as carbon emission, this will give rise to even greater energy demand and is ...
Combustion-derived black carbon (BC) aerosols accelerate glacier melting in the Himalayas and in Tibet (the Third Pole (TP)), thereby limiting the sustainable freshwater supplies for billions of people. However, the sources of BC reaching the TP remain uncertain, hindering both process understanding...
Further evidence for charge transfer complexes in brown carbon aerosols from excitation-emission matrix fluorescence spectroscopy. The light-absorbing fraction of organic molecules in ambient aerosols, known as "brown carbon," is an important yet poorly characterized component. Despite... M Sabrina,Philli...
To calculate the carbon emission of sand casting processes and to realize the targeted energy-saving and emission-reduction,a modeling method for carbon emission of sand casting based on process carbon sources was proposed.With analyzing the feature of sand casting production processes,the process feat...
We developed a simple conceptual model that tracks nitrogen and carbon jointly through an N fertilized forest ecosystem. The stimulation of growth increases the litterfall and imports substrate for soil microorganisms. Microbial biomass forms according to the supply of C and N. The formation of microb...
