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

Abstract

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)
