Abstract: 利用上海金山石化点位2014年大气监测资料,分析石化地区SO2、NO2、O3、PM10和PM2.5随时间的变化趋势,为未来工业园区的合理规划布局提供理论基础和决策依据.结果表明:(1)常规大气污染物浓度具有明显的季节性特征,SO2 、NO2、PM10 、PM2.5冬季高浓度,夏季低浓度,O3变化趋势相反;(2)O3呈现明显单峰日变化,NO2 、PM10、PM2.5则出现双峰现象,这是由于太阳辐射增强造成光化学反应加剧、地面温度上升以及人类活动的影响.SO2受太阳辐射影响较小,日变化趋势不明显.(3)污染物浓度风向分析表明,测点常规污染物主要来源于金山新城排放,但化工区废气排放对O3浓度具有明显影响.
