| 中文摘要 |
| 监测泰山顶O3及其前体物CO的浓度,分析O3和CO浓度的变化规律及其相关性.结果表明,泰山顶O3小时平均浓度超过国家一级标准的频率为15.81%,CO小时平均浓度均达标;O3浓度的日变化幅度较小,说明该地区受周围工业污染影响较小;O3和CO浓度的日变化均呈一高一低的双峰型变化规律,二者具有很好的相关性,O3浓度峰值一般滞后于CO,该区域O3及其前体物CO浓度的变化主要受局地光化学过程控制;O3浓度与CO浓度的日际变化的相关性也较好. |
| 英文摘要 |
| The concentrations of ozone(O3) and carbon monoxide(CO) on the top of Taishan Mountain were monitored,and the variations and correlation were studied.The results show that the frequency of O3 hourly concentrations more than the first-degree of National Ambient Air Quality Standard(GB-3095-1996,NAAQS) was 15.81%,and the frequency of CO concentrations more than the first-degree of NAAQS was zero.The variation of O3 concentrations appears in a narrow scope,which indicates that there is scarcely influenced by the pollution of industry around.The diurnal variation of the concentrations of O3 and that of CO both present two peaks with the peaks of O3 in the behind of CO,which indicates that the concentration variations of O3 and its precursor CO are primarily controlled by local photochemical reaction process.The daily concentrations of O3 correlated well with CO. |
