| 摘 要： | 采用温和溶剂提取方法对不同老化时间土壤中的菲进行提取,研究了正丁醇、二氯甲烷、2-羟丙基-β-环糊精(2-Hydroxypropyl-beta cyclodextrin,HPCD)提取量与生物吸收之间的相关性。结果表明,温和有机溶剂(二氯甲烷、正丁醇)提取与温和HPCD提取法对菲的提取量与蚯蚓蓄积量有很好的相关性(p<0.05)。与其他温和试剂提取相比,温和正丁醇提取可以更好地预测菲在土壤中的生物有效性。

| Abstract: | In order to explore correlations between biosorption and extraction of phenanthrene in soil with different extractants (acetone, dichloromethane, butanol, ethyl acetate and 2-Hydroxypropyl-beta cyclodextrin, HPCD), phenanthrene in soils different in aging were extracted with mild solvent extraction methods. A significant relationship was observed between the amount of phenanthrene extracted with mild organic extractants (dichloromethane and butanol) and with mild HPCD and phenanthrene accumulation in earthworms (p < 0.05). The mild butanol extractant can be used to better predict bioavailability of phenanthrene in both aged and unaged soils as compared to the other mild extractants in the present study. |
