Abstract
[Objectives] To evaluate the pollution status of antibiotics in the soil of vegetable bases in Yangling District. [Methods] The contents of 19 antibiotics in 4 categories of quinolones, tetracyclines, sulfonamides and macrolides in soil samples from 20 bases were detected and analyzed using HPLC-MS/MS. [Results] The quinolones, sulfonamides and tetracyclines were all detected in 100% of soil samples, and the detection rate of macrolides was 62%. The average contents of the four antibiotics from high to low were quinolones (51.76 μg/kg) >tetracyclines (12.77 μg/kg)> sulfonamides (1.14 μg/kg) >macrolides (0.28 μg/kg), and norfloxacin, oxytetracycline, sulfamethazine and erythromycin were the main contents, respectively. According to the trigger value of ecological toxic effect of antibiotics in soil (100 μg/kg) proposed by the Steering Committee of the International Coordinating Committee for Veterinary Medicine (VICH), the contents of the four classes of antibiotics in the soil of the study area were all lower than the trigger value, indicating a small ecological risk. [Conclusions] Compared with other domestic research reports, the vegetable bases in this study area are also at a relatively low level of antibiotic pollution.
