| 摘 要： | 通过土柱淋溶实验探讨了4种典型喹诺酮类抗生素诺氟沙星(NOR)、环丙沙星(CIP)、洛美沙星(LOM)、恩诺沙星(ENR)在土壤中的迁移行为及影响因素(污染程度、淋溶液pH和淋溶时间)。结果表明,喹诺酮类抗生素在低污染程度(≤4 mg·kg-1)下只迁移至40~50 cm层(0.2μg·kg-1),在高污染程度(20 mg·kg-1)下可迁移至90~100 cm层(4.7μg·kg-1),不同化合物的迁移能力强弱顺序为NORCIPLOMENR;在酸性条件(pH=5)下各化合物的迁移能力最强,可迁移至70~80 cm层(3.0μg·kg-1),在其余条件(pH=3、7、9)下只迁移至40~50 cm层(0.3μg·kg-1);淋溶时间较短(≤3 d)时只迁移至30~40 cm层(0.1μg·kg-1),淋溶时间为5 d时可迁移至90~100cm层(4.0μg·kg-1)。因此,土壤中喹诺酮类抗生素在污染较严重、长时间降水尤其是弱酸性降水时易于迁移。
