摘要
为了解河北省廊坊地区大气污染水平、变化特征以及污染物来源,2009年7月—2010年6月对该地区大气中NO、NO x(NO x=NO+NO2)、O3、SO2和PM10进行了连续在线观测,并用统计方法和后向轨迹模拟对所获数据进行分析。结果表明,一次污染物NO、NO x、SO2和PM10浓度具有相似的季变化和日变化,冬季浓度最高,季节日均值分别为(57±53)、(127±84)、(69±340)和(181±129)μg/m3;二次污染物O3夏季浓度最高,日小时均值最高值季节日平均为(99±39)μg/m3。一次污染物浓度日变化呈早晚双峰型,冬季,变化幅度最大;二次污染物日变化为单峰型,最大值出现在夏季午后。夏季受东南气流影响,往往造成该地区O3超标;冬季,廊坊和天津污染具有较高一致性,出现区域性大气复合污染。廊坊地区大气污染除受本地排放影响,还受到周边地区污染物输送的影响,其在京津两大城市间对大气污染的缓冲作用也不可小觑。
