| Abstract: | Pollution situation and change tendency of aldehydes and ketones in urban air were analyzed in 2003.It was indicated that the concentration of aldehydes and ketones were from Not Detection to 167 μg/m3,the main pollutants were formaldehydes,aldehydes and acetone.The content levels of pollutants in different seasons were summerspring winter.The aldehydes and ketones in the air were derived from the photochemical reaction of organics.There were significant correlation between formaldehydes and aldehyde,also between formaldehyde and acetones. |
