The presence of drugs in urban sewage and water ecosystems poses a significant health and environmental problem. Analyzing drugs in wastewater is difficult due to their low concentrations and presence in complex media, requiring advanced analytical methods. This review discusses recent developments in analyzing drugs in sludge, sediments, soils, and biota, comparing and discussing the advantages and disadvantages of different extraction methods and analytical steps for various sample types.
The use of psychoactive substances, including illegal drugs, drugs of abuse and psychiatric pharmaceuticals, is a major health and environmental issue. In particular, drugs are found in urban sewage and water ecosystems. The analysis of drugs in wastewater is challenging because drugs occur at trace levels in complex organo-mineral media, calling for advanced analytical methods. Here we review recent methods developped to analyze drugs in sludge, sediments, soils and biota. Extraction methods include solid-liquid extraction, sonication, microwave, and quick, easy, cheap, effective, rugged and safe extraction (QuEChERS). We compare and discuss advantages and disadvantages of each analytical step for various sample types.
