Variations of nitrate and sulfate in the atmosphere on days of high and low particulate matters.


Particulate matters with aerodynamic diameter less than 10 microm (PM10) were collected with high-volume samplers for four periods of consecutive samplings. Each period included a high PM10 (defined as PM10 > or = 110 microg/m3) episode. The concentrations of all ionic species of high PM10 day (HPD) samples were higher than those of low PM10 (defined as… (More)
