Ammonia as a significant contributor to the dry atmospheric deposition of nitrogen
Hejková, Mariana ; Hůnová, Iva (advisor) ; Lhotka, Radek (referee)
This bachelor thesis is based on a literature review on the topic of ammonia (NH3) as a significant contributor to the dry atmospheric deposition of nitrogen. The thesis gathers existing knowledge about NH3 and its role in environmental pollution. It addresses the extent of the extent to which ammonia influences dry atmospheric nitrogen deposition. The first part of the thesis discusses the emission sources of ammonia and its behavior in the atmosphere, including its chemical transformations, residence time in the atmosphere, and deposition mechanisms. It also describes the impacts of atmospheric ammonia deposition on ecosystems, whether it is eutrophication of water bodies, soil acidification, damage to aboveground and underground parts of plants, or disruption of biodiversity in aquatic and terrestrial ecosystems. The thesis highlights stagnant, and in some parts of the world, rapidly increasing ammonia emissions. Ammonia does not have a legislatively established immission limit, so its deposition fluxes are not regularly monitored in national monitoring networks. The author attempts to argue that ammonia should be included in the list of air pollutants with an immission limit. Key words: NH3, atmospheric deposition, emission sources, dry atmospheric deposition, temporal trends, ecosystems
