Abstract

In Korea, over 4,700 animal carcass disposal sites were installed until 2011 due to the outbreak of foot and mouth disease. Due to the putrefaction of buried animals, the leachate containing veterinary antibiotics may release into surrounding environments. Antibiotic residues in the environment cause the formation of antibiotic resistance bacteria threatening human and ecosystem health. This study reports the concentrations of five antibiotics, including tetracycline (TC), chlortetracycline (CTC), oxytetracycline (OTC), sulfamethazine (SMZ), and sulfamethoxazole (SMX), in soils from animal carcass disposal site and adjacent agricultural field. Concentrations of antibiotics at animal carcass disposal sites (TC: 144.26−350.73 µg/kg, SMZ: 17.72−44.94 µg/ kg) were higher than those at agricultural field (TC: 134.16− 320.73 µg/kg, SMZ: 6.48−8.85 µg/kg) whereas the concentrations of CTC, OTC, and SMX were below detection limit in both sites. Results showed that the antibiotics in animal carcass site might leach to the soil and possibly contaminating the groundwater. Future studies will focus on the transfer of antibiotics residues into food crops.
