Short summary

N-NH₄+ and N-NO₃- were vital components in nitrogenous aerosols and contributed 69 % to total nitrogen in PM_2.5. Coal combustion was still the most important source of urban atmospheric NO₃-. However, the non-agriculture sources play an increasingly important role in NH₄+ emissions.
