The analysis of municipal wastewaters for drugs and their metabolic products to estimate community consumption is a developing field, involving scientists working in different research areas, including analytical chemistry, physiology, biochemistry, sewage engineering, spatial epidemiology and statistics, and conventional drug epidemiology. The EUDA webpage presents the findings from studies conducted since 2011. Data from all studies can be explored through an interactive tool, and a detailed analysis of the findings of the most recent study, in 2024.
