Abstract
Ambient air aldehyde analysis was performed in Schenectady, NY. The Technique, as prescribed by Kuntz et. Al. (7), entailed the trapping of the volatile aldehydes as their 2,4-dinitrophenylhydrazone derivatives in an acetonitrile solution. The derivatives were then separated on a reversed phase HPLC column and detexted by UV absorption at 254 and 360 nm., simultaneously. The air in Schenectady was found to contain formaedehyde and acetaldehyde at concentrations which ranged from .70 to 30.5 ppb and below that of detection to 1.6 ppb, respectively. Formaldehyde's daily average in Schenectady was 7.6 ppb. The formaldehyde and acetaldehyde levels at Whiteface Mtn. ranged between .61-2.6 ppb and .33-.80 ppb, respectively. In addition, hourly sampling at both locations showed a diurnal variation in formaldehyde.
