Abstract:

通过210Pb定年建立相应时间标尺,获得了若尔盖红原县泥炭柱中多环芳烃(PAHs)的含量和垂直分布特征。结果表明,泥炭中总PAHs的浓度为36.2~408ng/gdw,PAHs与泥炭TOC的含量具有较好的相关性。自20世纪初开始,PAHs浓度呈明显上升趋势,在1960年代初期达到峰值,其后开始下降。PAHs组成上主要以3~4环化合物为主,其中菲占总PAHs的45%,其次是荧蒽(16%)和芘(10%),体现出大气沉降来源的PAHs组成特征。PAHs成因判识指标表明,该地区泥炭中PAHs主要源自燃煤和汽车尾气排放;结合气流轨迹分析,我们认为四川盆地可能是其主要源区。泥炭中PAHs的浓度变化与泥炭TOC的含量、温度和降雨量有关。
