In this in-depth focus, articles illustrate how mass spectrometry‑based wastewater analysis can estimate illicit drug usage and explore the applications of mass spectrometry in characterising therapeutic antibodies.
Analysis of illicit drugs and wastewater-based epidemiology: current methodological techniques
Ayman AlSaadi and Wayne G Carter from the School of Medicine, University of Nottingham, illustrate the value of analysing the wastewater of specific populations to gain insight into levels of illegal drug usage and other health-related biomarkers.
