The proliferation of new psychoactive substances (NPS) over recent years has made their surveillance complex. analysis raw municipal influent wastewater can allow a broader insight into community consumption patterns NPS. This study examines data from an international program that collected and analysed samples up to 47 sites in 16 countries between 2019 2022. Influent were the New Year period using validated liquid chromatography - mass spectrometry methods. Over three years, total 18 NPS...
The complexity around the dynamic markets for new psychoactive substances (NPS) forces researchers to develop and apply innovative analytical strategies detect identify them in influent urban wastewater. In this work a comprehensive suspect screening workflow following liquid chromatography - high resolution mass spectrometry analysis was established utilising open-source InSpectra data processing platform HighResNPS library. total, 278 wastewater samples from 47 sites 16 countries were...
Abstract This study employed the wastewater‐based epidemiology (WBE) strategy to investigate cocaine (COC) and ecstasy (MDMA) usage during Carnatal festival in Rio Grande do Norte, Brazil. Wastewater samples were collected over four days (December 12–15, 2019), as well corresponding before after event. The underwent filtration, acidification, solid‐phase extraction (SPE) for pre‐concentration, analysis using ultra‐high‐performance liquid chromatography–tandem mass spectrometry (UHPLC–MS/MS)...
