郑州市大气环境中醛酮类化合物污染状况初探

Research on Aldehydes and Ketones Pollutants in Zhengzhou Ambient Air

在郑州市交通密集区、工业区、居民文化区等不同功能区设置监测点位,分春季、夏季、冬季不同季节对郑州市大气环境中15种醛酮类的污染状况进行初步研究。结果表明,郑州市大气环境中醛酮类主要污染物为甲醛、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;功能区的变化趋势是交通密集区>居民区;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。

Sampling in different seasons and different areas,analyzing the aldehydes and ketones pollutants in Zhengzhou ambient air,the results shows： the main pollutants are formaldehyde,aldehyde and acetone.The pollutants level is summer higher spring,spring higher winter.And the main pollutants source root in organic pollutants photochemistry reaction in ambient air.The results also show strong relativity between formaldehyde and aldehyde,formaldehyde and acetong too.
