Fluoroquinolones, sulfonamides and macrolides were analyzed in soil samples collected from suburban areas in Tianjin, China. Fluoroquinolones were the predominant class of antibiotics. The mean total concentration of fluoroquinolones (33.56 μg/kg) was 30-fold higher than one of macrolides, which were the second dominant class antibiotics. Sulfonamides showed the lowest level in soil. The spatial distribution of fluoroquinolones showed wastewater irrigation was a potential source of antibiotics. The individual antibiotics levels were all below the trigger value (100 μg/kg) set by the Steering Committee of Veterinary International Committee, indicating the low risk for organisms in the agricultural soils of Tianjin.
氟喹诺酮类、磺胺类和大环内酯类抗生素在中国天津郊区的土壤样本中进行了分析。氟喹诺酮类是主要的抗生素类别。氟喹诺酮类的平均总浓度（33.56μg/kg）是大环内酯类的 30 倍，后者是第二大主导抗生素类别。磺胺类在土壤中含量最低。氟喹诺酮类的空间分布表明，污水灌溉是抗生素的潜在来源。单独的抗生素水平都低于兽医国际委员会指导委员会设定的触发值（100μg/kg），表明天津农业土壤中的生物风险较低。
