摘要:
以叶用莴苣为供试材料,采用盆栽试验对7种典型兽用抗生素[磺胺嘧啶(SDZ)、氟苯尼考(FF)、盐酸环丙沙星(CIP)、盐酸林可霉素单水化合物(LCM)、盐酸强力霉素(DOX)、头孢噻呋(EFT)、泰乐菌素(TYL)]在土壤-叶用莴苣中的转运规律进行研究,以评价其环境风险。结果表明种植叶用莴苣的土壤中兽用抗生素降解速率明显高于无叶用莴苣组,暴露时间与抗生素残留量呈负相关;土壤中兽用抗生素初始含量越高,兽用抗生素降解越快,最易降解的是EFT,最难降解的是FF。叶用莴苣中兽用抗生素含量随暴露时间延长不断增加,除EFT外其他6种兽用抗生素有富集。SDZ、FF、CIP、LCM在叶用莴苣茎叶的转运能力和富集量大,在叶用莴苣中食用风险高, DOX和TYL在叶用莴苣中食用风险小。
Abstract:
In this pot experiment, the transport of seven veterinary antibiotics, such as sulfadiazine (SDZ), florfenicol (FF), ciprofloxacin (CIP), lincomycin (LCM), doxycycline (DOX), ceftiofur (EFT), tylosin (TYL), in soil-lettuce was studied by using lettuce as the experimental material, so as to evaluate environmental risks. The results showed that the degradation rate of veterinary antibiotics in the soil planted with lettuce was significantly higher than that in the soil without lettuce, and the exposure time was negatively correlated with the amount of antibiotic residues. The higher initial content of veterinary antibiotics in the soil, the faster degradation rate of antibiotics. EFT was the most easily degraded, and FF was the most difficult to degrade. With the increase of exposure time, the content of veterinary antibiotics in lettuce increased continuously. Six kinds of antibiotics had enrichment phenomenon except EFT. The transport capacity and enrichment of SDZ, FF, CIP and LCM in the stems and leaves of the lettuce were large, so it had high risk to eat them. On the contrary, DOX and TYL had low edible risk in lettuce.
