Short summary
A low GEM level indicated that the SCS suffered less anthropogenic influence. There was no significant difference in GEM and HgP2.5 values between day and night, but the RGM level was higher in daytime than in nighttime. The size distribution of HgP in PM10 was observed to be bi-modal, but the coarse modal was the dominant size. The annual emission flux of Hg0 from the SCS was estimated to be 159 ton yr-1. The dry deposition was an important pathway for the input of atmospheric Hg to the SCS.
