MARTÍNEZ-CARBALLO, E.; GONZÁLEZ-BARREIRO, C.; SCHARF, S.; GANS, O. (2007): Environmental monitoring study of selected veterinary antibiotics in animal manure and soils in Austria. Environmental Pollution, 148, 570-579


LC–MS/MS was used for determination of selected tetracyclines, sulfonamides, trimethoprim, and fluoroquinolones in manure samples of pig, chicken and turkey, as well as arable soils fertilized with manure. Recoveries from spiked samples ranged from 61 to 105%. Method quantification limits were set to 100 μg/kg for all substances. Analysis of 30 pig manure, 20 chicken and turkey dung, and 30 lyophilized soil samples taken in Austria revealed that in pig manure up to 46 mg/kg chlortetracycline, 29 mg/kg oxytetracycline and 23 mg/kg tetracycline could be detected. As representatives of the group of sulfonamides, sulfadimidine in pig manure and sulfadiazine in chicken and turkey dung were detected in significant amounts (maximum concentration, 20 and 91 mg/kg, respectively). Enrofloxacin was particularly observed in chicken and turkey samples. Positive detection of chlortetracycline, enrofloxacin, and ciprofloxacin, in soil samples should be outlined as most important results of this study.

Specific exposure data of selected veterinarian antibiotics in manure and samples of agriculturally used soils are reported for the first time in Austria.
