The residue of antibiotics is becoming an intractable environmental problem in many organic vegetable bases. However, their residual levels and distribution are still obscure. This work systematically analyzed the occurrence and migration of typical veterinary antibiotics in organic vegetable bases, northern China. The results showed that there was no obvious geographical difference in antibiotic distribution between soil and manure. A simple migration model can be easy and quick to predict the accumulation of antibiotics in soil. Antibiotics were mainly taken up through water transport and passive absorption in vegetables. The distribution of antibiotics in a plant was in the sequence leaf>stem>root, and performed biological accumulation. The residues of antibiotics in all samples in winter were significantly higher than those in summer. Overall, this work can lay the foundation for understanding ecological risk of antibiotics and their potential adverse effects on human health by food chain.
抗生素残留正在成为许多有机蔬菜基地的一个棘手的环境问题。然而，它们的残留水平和分布仍然不清楚。本工作系统地分析了中国北方有机蔬菜基地中典型兽药抗生素的发生和迁移。结果表明，土壤和粪肥中抗生素的分布没有明显的地域差异。一个简单的迁移模型可以很容易和快速地预测抗生素在土壤中的积累。抗生素主要通过水运输和蔬菜的被动吸收被吸收。抗生素在植物中的分布顺序为叶>茎>根，并表现出生物积累。冬季所有样本中抗生素的残留量明显高于夏季。总的来说，这项工作可以为了解抗生素的生态风险及其通过食物链对人类健康的潜在不良影响奠定基础。
