The results showed that at the same concentrations, the total amount of test PAHs adsorbed by the K. candel and A. marina leaf litters had no significant difference, in spite of their decomposition status. The adsorbed amount of the PAHs tended to increase with their increasing concentrations. The litters had a higher adsorption rate of or exhibited selective adsorption to phenathrene and chrysene when the PAHs concentrations were lower, and had a higher adsorption rate of benzo perylene when the PAHs concentrations were higher.

结果显示：在同等PAHs浓度下，秋茄和白骨壤落叶碎屑对4种PAHs的吸附总量相近，树种间或分解状态间的吸附差异不显著；随着PAHs浓度的增加，2种红树植物落叶碎屑对4种PAHs的吸附率均呈现逐渐增加的趋势；PAHs浓度较低时，落叶碎屑对和菲有较高的吸附率或选择性吸附，PAHs浓度较高时，落叶碎屑对苯并芘吸附率提高。
