摘要
对郑州市2004年环境空气中多环芳烃的污染状况及变化规律进行了初步研究,结果表明,郑州市环境空气中15种优控PAHs的浓度范围为未检出-698ng/m^3,强致癌性物质苯并(a)芘的检出率为100%,其浓度范围为1.56-136ng/m^3。PAHs类物质在不同季节的变化趋势为冬季〉秋季〉春季〉夏季;在不同功能区变化趋势为工业区〉混合区〉交通密集区〉文化区〉对照区。
The contamination and variatio of Polycyclic Aromatic Hydrocarbons(PAHs) in the Air of Zhengzhou" city was studied Results showed that the concentrations of PAHs and Benz (a) pyrene were ND - 698ng/m^3 and 1,56 - 136ng/m^3 . The variational regulation in different seasons and different areas is ( 1 ) winter 〉 autumn 〉 springtime 〉 summer and ( 2 ) industrial estate 〉 omnibus area 〉 dense transportain area 〉 culture area 〉 check.
