Detection of oxytetracycline and chlortetracycline residues in agricultural fields in Turkey

Abstract

Tetracycline residues in the soil were investigated in this study due to their wide use in veterinary medicine and fertilization of agricultural fields with manure containing antibiotics. Soil samples were characterized by using various physicochemical parameters. Solid phase extraction and high performance liquid chromatography were used to detect oxytetracycline and chlortetracycline residues in the soils. The mean recovery rates of oxytetracycline and chlortetracycline were 51.07±27.66% and 62.12±17.05%, respectively. The concentrations of tetracyclines detected in soil samples were ranged from 0.019 mg kg-1 to 0.144 mg kg-1.
