标题：The Progress of Sustainable Management of Ammonia Emissions from Agriculture in European Union States Including Poland—Variation, Trends, and Economic Conditions
摘要：Ammonia (NH<sub>3</sub>) is one of the gases adversely affecting the natural environment. The greatest contributor to emissions of this gas to the atmosphere is agricultural activity. The main objective of the study was to assess the progress of sustainable management of ammonia emissions from agriculture in European Union countries. The specific objectives of the article were the following: to analyse and diagnose the level of ammonia emissions from agriculture, to study the diversity of emissions of this gas between countries, to analyse trends in the years 2010–2017 and, above all, to assess the relationship between the level of ammonia emissions from agriculture and the economic conditions of EU countries. The theoretical part of the article describes the causes and effects of, as well as preventive actions against, ammonia emissions from agriculture, whereas the empirical part analyses the problems, trends, variations, and the impact of economic conditions on emissions of this gas in 2010–2017. To evaluate the range of problems discussed, indicators describing ammonia emission levels Y<sub>01A</sub> and Y<sub>01B</sub>, as well as indicators characterising economic conditions X<sub>01</sub>, X<sub>02</sub>, and X<sub>03</sub> have been employed. During the study, the following indicators were analysed: ammonia emissions from agriculture in kilograms per hectare (Y<sub>01A</sub>), ammonia emissions from agriculture—percentage of total emissions (Y<sub>01B</sub>), government appropriations or outlays on research and development in agriculture in EUR per capita (X<sub>01</sub>), agricultural factor income in EUR per annual work unit (AWU) (X<sub>02</sub>), and real GDP in EUR per capita (X<sub>03</sub>). The source for the empirical data was information from the European Statistical Office (Eurostat). The analysis covered 28 states of the European Union. In the article, among others, the rate of change indices, coefficients of variation (V<sub>s</sub>), measures of distance (D) and range(R), coefficients of asymmetry (A) and kurtosis (K) were calculated, and correlation and regression analysis were performed. The share of agriculture in total ammonia emissions in European Union countries is very high and averages as high as 92%. Most of the countries maintain an upward tendency; a disturbing fact, considering such high ammonia emissions from agriculture. Based on the present analysis, it has also been confirmed that countries with the relatively highest levels of economy and agricultural research and development funding in fact emit more and increasingly more ammonia from agriculture. To avoid the intensification of the adverse effects of this phenomenon, all EU Member States should take effective, efficient, and sustained action to reduce ammonia emission levels.
