重庆市主城区PM10与能见度相关性研究
Relativity between PM10 and Visibility on Chongqing Urban Area
【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PM10的污染现状,能见度和PM10质量浓度负相关,尤其采样期间的相关系数为-0.76。根据PM10源解析和PM10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。
【Abstract】 The variety and trend of visibility from 2000 with PM10 pollution concentration in 2006 at Chongqing urban area were analyzed.The result showed that there was a distinct negative relativity between the visibility and the PM10 concentration,r-0.76 especially during the period of sampling.According to the PM10 source apportionment and the relativity between the PM10 chemical components and the visibility,it was proposed that priority pollutants to be controlled were coal dust and motor vehicle exhaust gas.
