	abstract = {This paper describes the method used to create an ammonia inventory for Denmark and presents the emission factors used and their justi"cation. The total Danish emission for 1996 was 92,700 t NH4-N, with agriculture accounting for nearly 99\%. Emissions from animal manure accounted for 76\% of agricultural emissions. We conclude that there will be a continued demand for inventories based on emission factors, despite their lack of physical and chemical realism, but that they will become more complex. This will place increased demands on the statistical information available and on the knowledge of the underlying science.},

	title = {Validation of model calculation of ammonia deposition in the neighbourhood of a poultry farm using measured NH3 concentrations and N deposition},
	journal = {Atmospheric Anvironment},
	volume = {43},
	year = {2008},
	abstract = {Substantial emission of ammonia (NH3) from animal houses and the related high local deposition of NH3- N are a threat to semi-natural nitrogen-deficient ecosystems situated near the NH3 source. In Denmark, there are regulations limiting the level of NH3 emission from livestock houses near N-deficient ecosystems that are likely to change due to nitrogen (N) enrichment caused by NH3 deposition. The models used for assessing NH3 emission from livestock production, therefore, need to be precise, as the regulation will affect both the nature of the ecosystem and the economy of the farmer. Therefore a study was carried out with the objective of validating the Danish model used to monitor NH3 transport, dispersion and deposition from and in the neighbourhood of a chicken farm. In the study we measured NH3 emission with standard flux measuring methods, NH3 concentrations at increasing distances from the chicken houses using passive diffusion samplers and deposition using 15N-enriched biomonitors and field plot studies. The dispersion and deposition of NH3 were modelled using the Danish OML-DEP
model. It was also shown that model calculations clearly reflect the measured NH3 concentration and N deposition. Deposition of N measured by biomonitors clearly reflected the variation in NH3 concentrations and showed that deposition was not significantly different from zero (P < 0.05) at distances greater
than 150{\textendash}200 m from these chicken houses. Calculations confirmed this, as calculated N deposition 320 m away from the chicken farm was only marginally affected by the NH3 emission from the farm. There was agreement between calculated and measured deposition showing that the model gives true estimates of the deposition in the neighbourhood of a livestock house emitting NH3},

	journal = {J. Limnol. },
	volume = {67},
	year = {2008},
	pages = {75-86},
	abstract = {Eighteen small shallow lakes located in the Northern Patagonian Lake District, in southern South America, were sampled in
2001 and analysed for the main chemical variables (pH, conductivity, alkalinity, major ions and nutrients). The study lakes span a
wide geographical and altitudinal range and belong partly to the Pacific and partly to the Atlantic watershed. The main aim of this
study was to investigate the relationships between water chemistry and physical/geographical properties of these lakes. Secondly, the
nitrogen content of the lakes was considered in detail, and results compared to those obtained in previous studies carried out in other
remote areas of the globe (the Central Southern Alps in Italy, the Sierra da Estrela region in Portugal, the Svalbard Islands in the
Arctic, the Khumbu-Himal region in Nepal, and the Terra Nova Bay area in Antarctica). In the Alps, lakes are characterised by
markedly high nitrogen concentrations, manly as nitrate, due to the high inputs of nitrogen compounds from downwind sources like
the Po Plain in Northern Italy. Conversely, lakes at remote locations such as the Andes, Antarctica and Himalaya are characterised
by a low nitrogen content, mainly as organic nitrogen. This status is related to the limited atmospheric inputs of nitrogen affecting
these regions.},
