PM2.5 samples were collected in four segregate one-month periods, each representing one season, for analyzing their contents of water soluble inorganic ions (WSIIs) in a small city inside Sichuan Basin. Daily PM2.5 concentrations ranged from 23.2 to 203.1 μg m-3 with an annual mean of 66.9 ± 33.6 μg m-3. Annual mean concentrations of WSIIs was 28.8 ± 20.3 μg m-3, accounting for 43.1% of PM2.5. Seasonal mean concentrations of WSIIs ranged from 17.5 ± 9.3 μg m-3 in summer to 46.5 ± 27.6 μg m-3 in… CONTINUE READING
