   During the summer of 2016, we observed intensively the behavior of atmospheric water-soluble acidic gases and anions in particle. The analytical system consisting mainly of a parallel plate wet denuder, mist chamber?hydrophobic filter based particle collector, and ion chromatograph provides automatically one acidic gas and one particle data in an hour. The average concentrations of nitric acid and sulfur dioxide were 2.82 nmol/m3 and 3.68 nmol/m3, meanwhile the nitrate and sulfate were 0.358 nmol/m3 and 6.21 nmol/m3 respectively(n = 64).
