| Abstract: |
| Veterinary antibiotics are widely used in breeding processes, thus, excessive antibiotics enter the farmland together with livestock manure and have a certain impact on soil ecosystems. In order to obtain the main conclusions and trends of existing studies and provide reference for studies on the risk of antibiotic residue in fecal manure, we collected data from relevant local and international journals, which were published in the past 10 years, and analyzed them. Relevant journals were obtained using keyword retrieval. Factors affecting fluoroquinolones, tetracycline, and sulfonamides antibiotics residues in the soil and their influence on soil microbial diversity were analyzed using Meta-analysis. Results showed that the degradation rate of antibiotics was faster in the first 7 days of entering the soil, after which, the rate reduced gradually. The final degradation rates of fluoroquinolones, tetracycline, and sulfonamides were about 77%, 85%, and 91% respectively. Soil pH and acid significantly affected the degradation rate of antibiotics in soil; weak acid soil was more conducive for antibiotic degradation. The concentration of the three antibiotics in soil above 10 mg·kg-1 inhibited the functional diversity of soil microorganisms. Sulfonamides had a significant inhibitory effect on soil microbial functional diversity. The effects of different antibiotics on soil microbial functional diversity was as follows:fluoroquinolone > sulfa > tetracycline. The soil degraded the antibiotics via natural degradation. The degradation capacity within 30 days was as follows:sulfa > tetracyline > fluoroquinolone. The lower the soil pH value, the higher the degradation rate. Antibiotics had a significant effect on soil microbial diversity; the higher the concentration, the more significant the inhibition was. When the pH of soil was 4.3~9.4, the higher the pH, the stronger the influence of antibiotics on soil microbial diversity. |
