摘要
2003年对郑州市城市环境空气中醛酮类化合物的污染状况及变化规律进行了初步调查研究。结果表明:大气环境中醛酮类污染物的质量浓度范围为未检出~167μg/m3,主要污染物为甲醛、乙醛和丙酮;醛酮类污染物含量在不同季节的变化趋势是:夏季〉春季〉冬季;醛酮类污染物主要来源于大气中有机物的光化学反应,甲醛与乙醛、甲醛与丙酮有较好的相关性。
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.
