Airborne reduced nitrogen: ammonia emissions from agriculture and other sources.
Ammonia is a basic gas and one of the most abundant nitrogen-containing compounds in the atmosphere. When emitted, ammonia reacts with oxides of nitrogen and sulfur to form particles, typically in the fine particle size range. Roughly half of the PM(2.5) mass in eastern United States is ammonium sulfate, according to the US EPA. Results from recent studies of PM(2.5) show that these fine partic...
متن کاملSpatial planning as a tool for decreasing nitrogen loads in nature areas
Deposition of nitrogen forms one of the largest threats to the vitality and biodiversity of Dutch nature areas. Of the two nitrogen compounds contributing to the total nitrogen deposition, Dutch sources of reduced nitrogen are estimated to contribute 47% to the total nitrogen deposition, whereas for oxidised nitrogen this is only 15%. For Dutch policy, it is therefore most effective to decrease...
متن کاملAmmonia emissions from livestock production in Chile: an inventory and uncertainty analysis
The objective of this work was to quantify the country’s NH3 emissions from livestock production. This calculation was based on the mass flow of total ammoniacal nitrogen (TAN). The analysis was performed for all 15 geographical regions in Chile. The definition of livestock subcategories was based on data from the Chilean Agriculture and Forestry Census as well as technical reports published by...
متن کاملEffects of agriculture upon the air quality and climate: research, policy, and regulations.
Scientific assessments of agricultural air quality, including estimates of emissions and potential sequestration of greenhouse gases, are an important emerging area of environmental science that offers significant challenges to policy and regulatory authorities. Improvements are needed in measurements, modeling, emission controls, and farm operation management. Controlling emissions of gases an...
متن کاملCost-effective N2O, CH4 and NH3 abatement in European agriculture: interrelations between global warming and acidification policies
In Europe agriculture is an important contributor to emissions of the acidifying compound ammonia (NH3) and the greenhouse gases nitrous oxide (N2O) and methane (CH4). Measures to reduce one of these gases may also have an impact on emissions of the others. This study investigates the effects of control options for NH3, N2O, and CH4 that are available for the European agriculture on the emissio...
