identify two differences between carbon 12 and carbon 14

Methane ( CH 4) is an important greenhouse gas that has 32 times the global warming potential (mass basis) of carbon dioxide ( CO 2) Seasons and wind directions are needed to provide a better source attribution in the AOSR. In the future, the isotopic characterization of CH 4 sources and measurements from different Our results confirm the importance of tailings ponds in regional CH 4 emissions and show that this method can successfullyĭistinguish wetland CH 4 emissions. Influenced by fossil CH 4 emissions from surface mining and processing facilities (56 ± 18 %), followed by fossil CH 4Įmissions from tailings ponds (34 ± 18 %) and to a lesser extent modern CH 4 emissions from wetlands (10 ± <1 %). The isotopic signatures of ambient CH 4 indicate that the CH 4 enrichments measured at the site were mainly

We tested the use of 14C and 13C carbon isotope measurements in ambient CH 4 from the AOSR toĮstimate source contributions from key regional CH 4 sources: (1) tailings ponds, (2) surface mines and processing facilities, and Developing approaches for evaluating reported methane ( CH 4)Įmission is crucial for developing effective mitigation policies, but only one study has characterized CH 4 sources in the Athabasca oil The rapidly expanding and energy-intensive production from the Canadian oil sands, one of the largest oil reserves globally, accounts for almostġ2 % of Canada's greenhouse gas emissions according to inventories.
