Quantification of methane emissions from latrines, septic tanks, and stagnant, open sewers in the woource that has previously received little attention..Combined global CH. emissions from latrines, septic sewage tanks, and stagnant, open sewers are estimated at 29 teragram per year (Tg/yr), with lower and upper bound ranges of 14 and 49 Tg/yr. Major uncertainties in the estimates are associated wi千篇一律 发表于 2025-3-30 18:56:43

Methane Emission By Grazing Livestockdual ruminant livestock freely grazing representative New Zealand pastures. The technique collects integrated ‘breath’ samples during grazing, using an implanted SF. source as a conservative calibrated tracer, an approach pioneered by Johnson .. . Most of these measurements have been on grazin固执点好 发表于 2025-3-31 05:04:51
Verifying agricultural emissions of methaneere. We have tested the efficacy of this approach for inferring average methane fluxes from regions of pastoral agriculture a few tens of km in extent In its simplest form, vertical concentration profiles are measured upwind and downwind of the target region, based on air samples collected from ligh内阁 发表于 2025-3-31 09:22:27

Methane budget in heavily polluted urban atmosphere derived from concentration and isotope data; A ccale budgets, especially in urban territories. As a greenhouse gas, methane may affect the climate changes, so due to the Kioto protocol its emission shell be limited.
