Abstract:The transport of selected four tetracycline antibiotics ,including tetracycline(TC), oxytetracyline(OTC), chlortetracycline (CTC) , doxytetracyline (DOXY) were investigated in a sandy soil. Manure was fortified with the compounds and then applied to soil plots to investigate leaching and surface run-off under field conditions. The results showed that: all the four tetracyclines were detected in surface run-off and leachate samples .The maxium concentrations were 0.2648 (TC), 0.3257 (OTC), 0.3708 (CTC) and 0.2392 μg/L (DOXY) in runoff and 0.1694 (TC), 0.2468 (OTC), 0.2302 (CTC) and 0.2123 μg/L (DOXY) in leachate, respectively. The transported antibiotics by surface run-off and leachate were ranged from 0.0011% to 0.0023% and from 0.00033% to 0.00054% of the antibiotics fortified to soil plots. The results indicated that tetracycline antibiotics can be transported by suface run-off and leachate in the field.
