A study finds that abatement of ammonia emissions along with simultaneous reduction in nitrogen oxides and sulfur dioxide emissions, all of which are measures intended to reduce the amount of nitrogen deposition over continental regions, may not lead to a full response in reduced forms of nitrogen deposition, given that the deposition of reduced nitrogen is decreased by only 60-80% per unit of ammonia abated, according to the authors.
