Analyses and decreasing patterns of veterinary antianxiety medications in soils

- The present study is the first record for determination of antianxiety drugs in soils.
- Ultrasonic-assisted extraction and LC/MS/MS were used for extraction and analysis.
- Dissipations of the tested drugs were investigated using batch soil incubation experiments.
- Two kinetic models were calculated and validated according to SANCO guideline.
- Acepromazine was more adsorptive and degradable, while xylazine was more sustainable and mobile.
