抗生素残留问题已成为有机蔬菜生产基地面临的一个突出的环境问题。然而，其残留水平和分布情况仍然不清楚。系统分析了我国北方有机蔬菜生产基地中典型兽用抗生素的发生和迁移规律。结果表明，抗生素在土壤和粪肥中的分布没有明显的地理差异。一个简单的迁移模型可以简单快速地预测抗生素在土壤中的积累。蔬菜对抗生素的吸收主要是通过水分运输和被动吸收。抗生素在植物体内的分布顺序为叶>茎>根，并进行生物积累。冬季各样品中抗生素残留量均显著高于夏季。总体而言，本研究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了基础。(C)2010爱思唯尔有限公司版权所有。
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. (C) 2010 Elsevier Ltd.
