THE INFLUENCING FACTORS OF SO42- AND NO3- IN PM10 IN JINHUA, CHINA

Sulfate (SO42-) and nitrate (NO3-) are the main secondary inorganic components in atmospheric particulates. It is of great significance to understand formation evolution air pollution process pollution. In this study, samples PM10 were collected Jinhua City eastern China from December 2019 January 2020 June August 2020, also analyzed influence different meteorological conditions gaseous pollutants on SO42- NO3- PM10. The results show that high relative humidity has a significant effect increase sulfur oxidation rate (SOR) winter, indicating winter liquid phase reaction more conducive SO42-. SOR nitrogen (NOR) decrease with increasing temperature summer. light intensity an important promoting both NOR, photochemical beneficial NO3-. Both precursors SO2 NO2 have effects O3 NOR higher than SOR, capacity greater NO3-, CO there negative correlation SOR.
