文摘为研究多芳环烃(PAHs)在虾夷马粪海胆Strongylocentrotus intermedius体内的富集动力学,系统认识其动力学参数特征,应用半静态双箱动力学模型拟合虾夷马粪海胆(壳直径2.0 cm±0.3 cm)对3,4-苯并[a]芘、9,10-二甲基蒽、3-甲基菲3种PAHs的生物富集过程,通过非线性拟合获得海胆对3种多环芳烃的吸收速率常数(K_1)、释放速率常数(K_2)、生物富集因子(BCF),以及平衡状态下海胆体内3种多环芳烃的含量(C_(max))、生物学半衰期(t_(1/2))等动力学参数。结果表明:海胆对3,4-苯并[a]芘富集动力学参数K_1、K_2、BCF、C_(max)、t_(1/2)的平均值分别为59.1、0.152、136.5、11.788μg/g和6.36 d;海胆对9,10-二甲基蒽富集动力学参数K_1,K_2、BCF、C_(max)、t_(1/2)的平均值分别为12.3、0.228、54.05、4.383μg/g和6.32 d;海胆对3-甲基菲富集动力学参数K_1、K_2、BCF、C_(max)、t_(1/2)的平均值分别为18.16、0.113、88.1、12.407μg/g和7.6 d;在5μg/L浓度条件下,海胆对3种多环芳烃的富集能力进行比较,依次为3,4-苯并[a]芘(14 d BCF=220)>3-甲基菲(14 d BCF=128.4)>9,10-二甲基蒽(14 d BCF=84.0)。研究表明,海胆对浓度为1、5、20μg/L的3,4-苯并[a]芘、浓度为5、100μg/L的3-甲基菲、浓度为5、10、50μg/L的9,10-二甲基蒽的生物富集过程均符合双箱动力学模型。
