Options and costs of controlling ammonia emissions in Europe
研究了欧洲33个地区控制氨排放的成本，包括低氮饲料、粪便储存覆盖等技术选项，发现各国因养殖结构和肥料使用差异导致成本不同，允许自主选择控制组合更经济。
Ammonia emissions contribute to acidification in Europe. The major emission sources are livestock and fertilizer use. This study presents the costs of controlling ammonia emissions in 33 regions in Europe. Abatement options include low nitrogen feed, stable adaptations, covering manure storage, cleaning stable air, and low ammonia applications of manure. Cost estimates are based on country- and technology-specific data. The structure of livestock population and fertilizer use mean that the cost of applying similar abatement options or techniques varies considerably. Allowing countries to choose their own mix of control options would be more cost-effective.
