| 摘 要： | 研究了多环芳烃（PAHs）在含6000a（马家浜文化时期）古水稻土的土壤剖面中的分布特征，并对其可能来源进行了分析。结果显示，各层土壤中PAHs的总量在25．9—202．9μgkg^-1之间，并主要富集在表层土壤，其中含量较高的化合物及其大小顺序为Nap〉Phe〉Fla〉Pyr，4环以上的PAHs占总量的51.8％。表层以下各层土壤中PAHs含量大幅降低，检出种类也有所减少，并主要以2、3环化合物为主，古水稻土中4环以上的芳烃也占有一定的比例，达37％。聚类分析和主成分分析表明，Chr、BkF、BaA、IcP、BbF、Pyr、BaP、DaA和Fla等化合物主要是人为产生，Flu和Phe由生物合成，而Nap、BgP和Ant则可能来源于人为产生和生物合成的共同作用。
