| 中文摘要: |
| 分析了2000年以来重庆市主城区能见度变化趋势及2006年PM 10 的污染现状, 能见度和 PM 10 质量浓度负相关, 尤其采样期间的相关系数为-0.76 。根据PM 10 源解析和 PM 10 成分与能见度的相关性分析结果 , 提出应重点控制燃煤和机动车尾气污染。 |
| 英文摘要: |
| The variety and trend of visibility from 2000 with PM 10 pollution concentration in 2006 at Chongqing urban area were analyzed. The resultshowed thatthere wasa distinctnegative relativity between the visibility and the PM 10 concentration, r -0.76 especially duringthe period ofsampling. Accordingto the PM 10 source apportionmentandtherelativity betweenthe PM 10 chemicalcomponentsandthe visibility,itwasproposed thatpriority pollutantsto be controlled were coaldustand motorvehicle exhaustgas. |
