Despite the multiple advantages of liquid chromatography-tandem mass spectrometry in the analysis of drug biomarkers in aqueous samples, gas chromatography-mass spectrometry (GC/MS) remains the workhorse of many environmental and public health monitoring laboratories. This presentation will describe efforts to develop and validate GC-based methods (MS and MS/MS) for the routine determination of illicit drug biomarkers in municipal wastewater. Biomarkers include those for cocaine, amphetamine, methamphetamine, ecstasy, marijuana, fentanyl, and heroin. The pros and cons of different derivatization approaches will be discussed.
