With the reduction of SOM content and the elevation of contamination concentration, the difference between PHE and PYE decreases gradually, while B［a］PYE exhibits a significant difference from them. This could be attributed to the high lipophilicity and large molecular size of B［a］PYE, which make the molecule of B［a］PYE to be more easier to be held in the nanopores of clay and the dense region of SOM.

不同多环芳烃SPMD辅助解吸率差别很大，随着土壤有机质含量的降低，以及污染物浓度的提高，菲和芘的解吸差异逐渐缩小，而苯并［a］芘与上述2种多环芳烃的差异很大，主要是由于苯并［a］芘具有高度亲脂性，并且分子较大，造成其容易滞留在粘土的微孔及有机质的致密结构中。
