抄録

Atmospheric gaseous and particulate oxalic acids were measured from April 20-23, 1998, during the day and night at an urban site, Urawa. To suppress filter artifacts, the samples were collected with the annular denuders-filter pack sampler. The concentrations of gaseous and particulate oxalic acids ranged from 320 ng/m<SUP>3</SUP> to 680 ng/m<SUP>3</SUP> (86.8 pptv to 185 pptv at 25 °C) and 403 ng/m<SUP>3</SUP> to 777 ng/m<SUP>3</SUP>, respectively. A negative filter artifact, the volatilization loss of particulate oxalic acid collected on quartz filter was estimated and corrected. The results showed that the filter artifact was not negligible and the concentration of particulate oxalic acid is remarkably underestimated due to the volatilization losses from the particulate matter collected on the filter without a back up media such as KOH-coated filter used in this study.
