Wastewater-based Tracing of Doping Use
The prevalence of doping in sport and in the community at large continues to be a π concern in many societies.
Numerous test protocols are in place to test individuals but the increased sensitivity of modern analytical techniques π and the purity of the ultrapure water available to use in testing have opened the scope for screening communal wastewater π for drugs and their metabolites.
Causanilles et al (1) have successfully developed and tested a procedure for 15 substances from the π groups of anabolic steroids (used to promote muscle growth), weight loss products (used to increase metabolism by burning fat) and π masking agents in wastewater using solid phase extraction to increase sensitivity and reduce matrix effects followed by liquid-chromatography coupled to π high resolution mass spectrometry.
50 ml of sample were spiked with an isotope-labeled internal standard, filtered, and acidified before concentration on π a mix-mode cationic polymer-based cartridge.
