Characteristics and Influencing Factors of Soil CH4 and N2O Fluxes in Typical Broad-leaved Forests in the Yangtze River Delta Region, China

Shuitu Baochi Xuebao
[Objective] The forest coverage rate in the Yangtze River Delta region reaches 33.4%, and the underlying surface soil may have an important impact on the regional greenhouse gas budget.

Proper interpretation of dissolved nitrous oxide isotopes, production pathways, and emissions requires a modelling approach. [PDF]

PLoS ONE, 2014
Stable isotopes ([Formula: see text]15N and [Formula: see text]18O) of the greenhouse gas N2O provide information about the sources and processes leading to N2O production and emission from aquatic ecosystems to the atmosphere.

The Optimization of Hypobromite Oxidation Combined with Sodium Azide Chemical Methods and Determination of the Nitrogen Isotopic Composition of Dissolved Ammonium in Seawater

Journal of Isotopes
Ammonium is a key dissolved inorganic nitrogen (DIN) in the biogeochemical cycle of nitrogen in the ocean. Depending on the environment，the 15N natural abundance (δ15Nair ) of NH4+ can provide insights into N sources and mechanisms of N transformations ...

Extreme emission of N2O from tropical wetland soil (Pantanal, South America)

Frontiers in Microbiology, 2013
Nitrous oxide (N2O) is an important greenhouse gas and ozone depleter, but the global budget of N2O remains unbalanced. Currently, ~25% of the global N2O emission is ascribed to uncultivated tropical soils, but the exact locations and controlling ...

Nitrous Oxide Emissions from Smallholders’ Cropping Systems in Sub-Saharan Africa

Advances in Agriculture, 2021
Increased concentration of atmospheric nitrous oxide (N2O), a potent greenhouse gas (GHG), is of great concern due to its impact on ozone layer depletion leading to climate change. Ozone layer depletion allows penetration of ultraviolet radiations, which

Key Drivers of Activity and Selectivity in Cu‐Based Catalysts for Methanol Synthesis From CO2: Insights From Atomically Dispersed Promoters

Angewandte Chemie, EarlyView.
Mechanistic studies on model Cu─M/SiO2 catalysts (M = Zn, Ga, and In) reveal that promoters enable a formate spillover pathway from Cu to Mn+ (n = 2 or 3) sites. The promoter's electronic effect on formate bond strengths serves as a quantitative descriptor for activity and selectivity, balancing spillover dynamics with intermediate stabilization to ...

Inland Waters can Act as Nitrous Oxide Sinks: Observation and Modeling Reveal that Nitrous Oxide Undersaturation May Partially Offset Emissions

Geophysical Research Letters, 2023
Inland waters are significant, yet highly uncertain, natural sources of nitrous oxide (N2O). Many emission models assume that N2O is only emitted from freshwaters, and that N2O sink behavior is negligible. However, observational studies have reported N2O

Marine N2O cycling from high spatial resolution concentration, stable isotopic and isotopomer measurements along a meridional transect in the eastern Pacific Ocean

Frontiers in Marine Science, 2023
Nitrous oxide (N2O) is a potent greenhouse gas and ozone depleting substance, with the ocean accounting for about one third of global emissions. In marine environments, a significant amount of N2O is produced by biological processes in Oxygen Deficient ...
