LC-MS-MS Method for the Analysis of Miscellaneous Drugs in Wastewater During Football Games III.

ABSTRACT

Continuing our previous studies analyzing drugs of abuse in municipal wastewater, a method was developed for the analysis of miscellaneous drugs of abuse in wastewater samples using liquid chromatography coupled with tandem mass spectrometry (LC-MS-MS). Eight drugs and metabolites were analyzed including 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrolidine (EDDP), fentanyl, norfentanyl, meperidine, normeperidine, methadone, phencyclidine and tramadol. These drugs were chosen because of their widespread abuse. Wastewater samples were collected at both the Oxford Waste Water Treatment Plant in Oxford, Mississippi (MS) and the University Wastewater Treatment Plant in University, MS. These wastewater samples were collected on weekends in which the University of Mississippi football team (colloquially the "Ole Miss Rebels" football team) held home games (Vaught-Hemingway Stadium, University, MS 38677). The collected samples were analyzed using a validated method and found to contain tramadol in 25 samples at quantifiable levels. EDDP, meperidine, normeperidine and methadone were also detected but were under the limit of quantitation.
