The distribution of nano/micron inorganic ions in size-segregated suburban aeroslo of southern Taiwan was studied for a PM episode and a non-episodic pollurtion period. Inorganic species, especially nitrate, were present in higher cincentrations druing the PM episode. Sulfate and ammonium were the dominant anion and cation, respectively, accounting for a minimum of 49% of the total anion or cation mass. Peak concentrations of these species occurred at 0.54 um in the droplet mode during both non-episodic and PM periods, indicating an assoeiation with cloud-processed particles. For total cations and total inorganic anions, major contributing particles were in the droplet mode, with least in the nuclei mode.
