A study of hazardous air pollutants in Gunma prefecture (III): Determination of aldehydes in ambient air

群馬県における有害大気汚染物質調査(III) LC/MSによるアルデヒド類の測定

Research overview:
In Gunma prefecture formaldehyde and acetaldehyde in the air are measured in monitoring system of hazardous air pollutants. With DNPH cartridge capturing LC/MS method good results was obtained without perturbation from co-existent compounds. The concentration of formaldehyde and acetaldehyde in the air at 5 points in this prefecture from June 1998 to March 2002 was 0.5 to 13 (aver. 3.9) microgram/m3 and N.D. to 10 (aver. 2.1) microgram/m3, respectively. And concerning the concentration of formaldehyde in this prefecture contribution of secondary formation by photochemical reaction is postulated to be significant.
