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 100μg/kg for all substances. Analysis of 30
pig manure, 20 chicken and turkey dung, and 30 lyophilized soil samples taken in Austria

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 100μg/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 46mg/kg chlortetracycline, 29mg/kg oxytetracycline and 23mg/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 91mg/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.
