Abstract

Based on aerosol sampling data in 2016 in Hangzhou, the influences of the G20 emission reduction on inorganic water-soluble ions in particulate matter (PM) was investigated. The results proved that the G20 emission reduction had significant impacts on mass concentration, composition and acid-base properties of water-soluble ions in PM. The concentrations of PM and its water-soluble ions were both reduced by the G20 emission reduction. Among them, the concentrations of NO₃^-, SO₄^2-, NH₄⁺ and NO₂^- decreased most obviously, and the concentration decrease of NO₃^- and SO₄^2- made the concentrations of NH₄⁺, Ca²⁺ and Cl^- the top three ions. The size distributions of SO₄^2-, NO₃^-, NH₄⁺ and Ca²⁺ showed mono-modals, and SO₄^2-, NO₃^- and NH₄⁺ were preferably enriched in the fine particles (within range of 0.65~1.10 mm) while Ca²⁺ in the coarse particles (within range of 5.80~9.00mm). The size distributions of Na⁺, Cl^- and K⁺ showed bi-modals with peaks at the particle size of 3.30~4.70mm and 0.65~1.10mm, respectively. the two peaks of Na⁺ were comparable while K⁺ and Cl^- had higher peak values in the size range of 0.65~1.10mm. The main inorganic salts were changed from NH₄NO₃, (NH₄)₂SO₄ and NH₄Cl to NH₄Cl, NaCl and KCl as well as the alkaline enhancement in PM by the G20 emission reduction. The results of this study could provide references for policy formulation and implementation for air quality improvement measures.
