Analysis of Illicit Drugs in Wastewater Using High-Performance Liquid Chromatography-Electrospray Ionization-Tandem Mass Spectrometry (HPLC-ESI-MS/MS).

Consumption of illicit drugs is considered to be a global socioeconomic burden of adverse ecological and public health. Proper identification and quantification of trace level residues of illicit drugs in wastewater allow for an estimation of drug usage in a community, the amount of drug discharge into the environment, and the overall fate of drugs in the environment. This chapter provides a procedural detail of the determination of select illicit drugs and their metabolites in wastewater, suspended particulate matter, and sewage sludge using high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry.
