Effectiveness of ammonia reduction on control of fine particle nitrate
In some regions, reducing aerosol ammonium nitrate (NH4NO3) concentrations may substantially improve air quality.This can be accomplished by reductions in precursor emissions, such as nitrogen oxides (NOx) to lower nitric Sticker Pack acid (HNO3) that partitions to the aerosol, or reductions in ammonia (NH3) to lower particle pH and keep HNO3 in th
