We collected 1 year of aerosol samples at Yongxing Island in the South China Sea. The concentrations of TSP and all major inorganic ions showed seasonal variations, with higher concentrations in the cool season and lower in the warm season; 60.5 % of NH4+ was from oceanic emission. Secondary inorganic aerosol of SO2 and NOx from fossil fuel combustion (especially coal in Chinese coastal regions) was the dominant source of NO3− (69.5 %) and SO42− (57.5 %).
