Nitrification is a primary driver of nitrous oxide production in laboratory microcosms from different land-use soils

Frontiers in Microbiology, 2016
Most studies on soil N2O emissions have focused either on the quantifying of agricultural N2O fluxes or on the effect of environmental factors on N2O emissions. However very limited information is available on how land-use will affect N2O production, and

Influences of Land Use/Cover Types on Nitrous Oxide Emissions during Freeze-Thaw Periods from Waterlogged Soils in Inner Mongolia.

PLoS ONE, 2015
Nitrous oxide emissions during freeze/thaw periods contribute significantly to annual soil N2O emissions budgets in middle- and high-latitude areas; however, the freeze/thaw-related N2O emissions from waterlogged soils have hardly been studied in the ...

Evaluation of Greenhouse Gas Emissions and Sludge Characteristics in Typical AAO Process WWTPs in Taihu Lake Basin, China

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigated sludge characteristics and greenhouse gas (GHG) emission from 16 anaerobic‐anoxic‐oxic (AAO) process wastewater treatment plants (WWTPs), 11 municipal and 5 industrial WWTPs, located in the Taihu Lake Basin, China. Influent/effluent water quality, sludge properties, operational parameters, GHG emission patterns, and ...

Biochar‐based fertilizers improve nutrient use efficiency in sunflower grown on a subtropical tidal soil

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Improving fertilizer use efficiency is essential for reducing environmental pollution, sustaining agricultural production, and maximizing the economic profitability of crop production systems. This study tested the hypothesis that the formulation strategy of biochar‐based fertilizers, rather than nutrient addition alone, is associated with ...

Intermediate soil acidification induces highest nitrous oxide emissions

Nature Communications
Global potent greenhouse gas nitrous oxide (N2O) emissions from soil are accelerating, with increases in the proportion of reactive nitrogen emitted as N2O, i.e., N2O emission factor (EF). Yet, the primary controls and underlying mechanisms of EFs remain

Soil Bulk Density and Moisture Content Influence Relative Gas Diffusivity and the Reduction of Nitrogen‐15 Nitrous Oxide

Vadose Zone Journal, 2014
Nitrous oxide is a greenhouse gas and contributes to stratospheric ozone depletion. Soil physical conditions may influence N2O reduction and subsequent N2O emissions.

Relationships among nitrous oxide exposure, neurological injury and biomarkers

British Journal of Clinical Pharmacology, EarlyView.
Aims Recreational nitrous oxide (N2O) misuse is an increasing public health problem associated with functional cobalamin (B12) deficiency and severe neurological complications. Despite growing recognition of its harms, the dose–response relationship and clinical value of biomarkers remain unclear.

Nitrous Oxide Generation, Influencing Factors and Emission Reduction in Anaerobic-Anoxic-Oxic Process Wastewater Treatment Plant [PDF]

E3S Web of Conferences
To achieve the reduction of emissions and control of non-CO2 greenhouse gases in municipal wastewater treatment plants, this study conducted a one-year monitoring of N2O in the A2O process of a large municipal wastewater treatment plant in Beijing.

Nitric oxide generation from nitrate at the cobalt center

Bulletin of the Korean Chemical Society, EarlyView.
Deoxygenation of a cobalt(II) nitrate complex with CO(g) or PPh3 yields a Co(NO)(NO2) species, which can alternatively be generated from a cobalt mononitrosyl complex, featuring a distinct {CoNO}8 core. Abstract Herein, we report the synthesis and reactivity of the cobalt(II) nitrate complex, (acriPNP)Co(NO3) (2).
