| 中文摘要: |
| 为明确河北地区典型设施菜地土壤中抗生素的污染现状和积累变化规律，本研究选取石家庄藁城、张家口崇礼和衡水武邑三地中连续耕种1~20 a不等的共计61个蔬菜大棚土壤，检测并分析了其抗生素残留特征。结果表明：三地设施菜地土壤中抗生素均有检出，其中以藁城地区土壤中抗生素残留量最高，这与其长期施加有机肥有关。抗生素总残留量范围为 3.97~342 μg·kg-1，其中90.2%的土样中抗生素总残留量未超过100 μg·kg-1。三地均存在四环素类抗生素残留量较高，喹诺酮类次之，磺胺类较低的现象。检出的 4类共 24种抗生素的残留组成具有区域差异性，藁城、崇礼、武邑地区残留量最高的分别是土霉素（26.7 μg·kg-1）、诺氟沙星（5.09 μg·kg-1）、强力霉素（9.92 μg·kg-1）。随着种植年限增加，仅藁城地区抗生素残留量显著上升，长期种植和施肥行为会导致厚壁菌门、放线菌门、变形菌门微生物丰度的上升。 |

| In order to clarify the pollution status and accumulation of antibiotics in the soil of typical vegetable plots in Hebei Province, a total of 61 greenhouse soils from Gaocheng, Chongli, and Wuyi, which had been continuously cultivated for 1 to 20 years, were selected to detect the characteristics of antibiotic residues. The results showed that antibiotics were detected in all three places, and the highest residues were found in the soil of Gaocheng due to the long-term application of organic fertilizer. The total residues of antibiotics ranged from 3.97 μg·kg-1 to 342 μg·kg-1, and 90.2% of the soil samples contained no more than 100 μg·kg-1. The residues of 24 antibiotics were different in different regions. The highest residues in Gaocheng, Chongli and Wuyi were oxytetracycline（26.7 μg·kg-1）, norfloxacin（5.09 μg·kg-1）and doxycycline（9.92 μg·kg-1）, respectively. With the increase of cultivating years, antibiotic residues increased significantly only in Gaocheng, and long-term planting and fertilization behavior would lead to an increase in the abundance of Firmicutes, Actinobacteriota and Proteobacteria. |
