Implication

Randomized trial analyzes anesthetic compounds in wastewater, indicating effective monitoring methods.

Key Points

  • The aim is to develop a method for measuring anesthetic-related compounds in municipal wastewater.
  • Used solid-phase extraction (SPE) with mixed-mode cation exchange for sample prep.
  • Optimized chromatographic separation on a Phenyl column with HPLC-MS/MS.
  • Analyzed 24 wastewater samples for occurrence and concentration of compounds.
  • All analytes showed strong linearity (R2 >0.999) with low limits of detection (0.172–1.74 ng L−1).
  • Mean recoveries ranged from 86.7% to 116.4% with RSDs below 15%.
  • Detection frequencies for analytes ranged from 17% to 100%, with concentrations up to 1.05 × 10^3 ng/L.
