Experimental determination of nitrous oxide emission factors for arable land. Experimental site in Devon, 2008 [PDF]

, 2016
At Rothamsted Research - North Wyke in south west England nitrous oxide (N2O) emissions were monitored following spring ammonium nitrate fertiliser applications at 6 different rates; 0 (i.e. untreated control), 70, 140, 210, 280 and 350 kg N ha-1.

Nitrogen Oxide Emissions Worldwide

Energy Exploration & Exploitation, 1998
Whilst it is relatively easy to quantify sulphur dioxide emissions worldwide, the situation with nitrogen oxide (NO x ) emissions is more complicated. In this article information is presented from two recently published IEA Coal Research reports, a UK DTI research report and information ...

Quantification of greenhouse gas emissions in biological wastewater treatment [PDF]

, 2014
There is an increasing need to reduce greenhouse gas (GHG) emissions and to identify influencing factors from wastewater treatment plants (WWTPs), particularly process emissions consisting of nitrous oxide (N2O), and methane (CH4) GHG, with global ...

Control of Oxides of Nitrogen in Automotive Emissions

Journal of the Fuel Society of Japan, 1971
In the combustion process of of automotive engines, gas temperature of post-flame reachs so high that the formation of nitric oxide become rapid reactions. By 1976 in the U.S.A., emission rate of NOx from light duty vehicle will be restricted less than 0.4g/mile, however one can not yet find a conventional technique to meet the 1976 emission standard ...

Nitrogen efficiency of dairy cattle : from protein evaluation to ammonia emission [PDF]

, 2011
Diet optimization contributes considerably to increased nitrogen efficiency of dairy cattle, resulting in reduced nitrogen losses. This thesis focuses on three themes: the potential advances in protein evaluation systems for ruminants, the relationship ...

Tracking nitrogen losses in a greenhouse crop rotation experiment in North China using the EU-Rotate_N simulation model [PDF]

, 2010
Vegetable production in China is associated with high inputs of nitrogen, posing a risk of losses to the environment. Organic matter mineralisation is a considerable source of nitrogen (N) which is hard to quantify.

Environmental change impacts on the C- and N-cycle of European forests: a model comparison study [PDF]

, 2013
Forests are important components of the greenhouse gas balance of Europe. There is considerable uncertainty about how predicted changes to climate and nitrogen deposition will perturb the carbon and nitrogen cycles of European forests and thereby alter ...

Satellite Evidence of HONO/NO2 Increase With Fire Radiative Power

Geophysical Research Letters, 2023
Wildfires are important sources of atmospheric reactive nitrogen. The reactive nitrogen species partitioning generally depends on fire characteristics. One reactive nitrogen compound, nitrous acid (HONO), is a source of hydroxyl radicals and nitric oxide,

Analysis of alternative pathways for reducing nitrogen oxide emissions

Journal of the Air & Waste Management Association, 2015
Strategies for reducing tropospheric ozone (O3) typically include modifying combustion processes to reduce the formation of nitrogen oxides (NOx) and applying control devices that remove NOx from the exhaust gases of power plants, industrial sources and vehicles.

Nitrogen Oxide (NOx) emissions as an indicator for sustainability

Environmental and Sustainability Indicators, 2022
Environmental data and research illustrate that global warming, normally assessed through carbon dioxide (CO2) and greenhouse gas (GHG) emissions, is a critical element in environmental sustainability and that a shift to decarbonized energy sources is necessary to preserve the environment for future generations.
