“…As shown by Lorenz and Steffens (1997), Webb et al (2006) and Kai et al (2008), a sustainable reduction of ammonia emissions between 20 to 90 % could be achieved, depending on the emission process and the methodology applied (e.g., slurry acidification, adjustment in slurry application, under-floor drying of broiler manure in buildings, replacing urea with ammonium nitrate). As the efficiencies of the abatement processes are not well established (Misselbrook et al, 2002), fixed relative reductions have been applied here to all agricultural emissions.…”

“…As the efficiencies of the abatement processes are not well established (Misselbrook et al, 2002), fixed relative reductions have been applied here to all agricultural emissions. Webb et al (2006) showed that for the United Kingdom a moderate reduction in ammonia emission is easily affordable, while the costs are likely to increase exponentially for reductions above 25 %. The same control measures would be even more difficult to apply in countries in which livestock production is projected to largely increase (such as Asia; Delgado et al, 2001), where they should be adopted on a large scale.…”

Abstract. A global chemistry-climate model has been used to study the impacts of pollutants released by agriculture on fine-particulate matter (PM 2.5 ), with a focus on Europe, North America, East and South Asia. Simulations reveal that a relatively strong reduction in PM 2.5 levels can be achieved by decreasing agricultural emissions, notably of ammonia (NH 3 ) released from fertilizer use and animal husbandry. The absolute impact on PM 2.5 reduction is strongest in East Asia, even for small emission decreases. Conversely, over Europe and North America, aerosol formation is not immediately limited by the availability of ammonia. Nevertheless, reduction of NH 3 can also substantially decrease PM 2.5 concentrations over the latter regions, especially when emissions are abated systematically. Our results document how reduction of agricultural emissions decreases aerosol pH due to the depletion of aerosol ammonium, which affects particle liquid phase and heterogeneous chemistry. Further, it is shown that a 50 % reduction of agricultural emissions could prevent the mortality attributable to air pollution by ∼ 250 000 people yr −1 worldwide, amounting to reductions of 30, 19, 8 and 3 % over North America, Europe, East and South Asia, respectively. A theoretical 100 % reduction could even reduce the number of deaths globally by about 800 000 per year.

“…The latter used local activity data and emission factors. In addition, mechanistic models such as NARSES (Webb et al, 2006) have been developed to simulate NH 3 emissions from agricultural fertilizer. To accurately determine NH 3 emissions from China's agricultural fertilizer, the aspects require further research: (1) Different sources of emissions.…”

“…However, methods differ in effectiveness, cost, practicality, and expertise required to operate them efficiently. Good results were obtained with covers, at least to reduce NH3 emissions (Brink et al, 2005;Webb et al, 2006;Ndegwa et al, 2008;VanderZaag et al, 2009). Stationary (a 'tight' lid, roof or tent structure) or floating covers can be used.…”

“…Stationary (a 'tight' lid, roof or tent structure) or floating covers can be used. Stationary covers are much more expensive than floating covers, and it is difficult to install them on large stores (Webb et al, 2006). There is a range of floating covers that could reduce NH3 emission from stored slurries.…”

Livestock manure is the source of different pollutant gases that can generate soil acidification, eutrophication, and contribute to global warming, or have a negative impact on health. Covers can control gas emissions from manure, but their impact is still under discussion. The aim of this experiment was to study the effect of different covers on methane (CH4), nitric oxide (NO), hydrogen sulfide (H2S), ammonia (NH3), carbon monoxide (CO), and carbon dioxide (CO2) emissions from liquid pig manure. Six types of floating covers were tested: light expanded clay aggregate (leca), peat, sunflower oil, sawdust, straw, and plastic film. Manure was stored at 5, 15, and 25 °C for 37 d. Gas emissions were measured from the headspaces of the dynamic chambers. The results of our study showed that both cover and temperature have a noticeable impact on gas emissions from liquid pig manure. The plastic film cover was the most efficient at all tested temperatures because it reduced emissions of all the measured gases. In this case, mean emission reductions were: CH4 91.5% (P < 0.01), NO 92.0% (P < 0.05), H2S 78.1% (P < 0.05), NH3 54.7% (P < 0.01), CO 98.4% (P < 0.01), and CO2 67.1% (P < 0.01). Other covers had an inconsistent impact on separate gas emissions. However, covers generally helped to decrease NH3, H2S, and CO2 emissions.
