Sažetak
The work presented in this paper reports on the application of sewage epidemiology approach for the estimation of the collective consumption of illicit and licit drugs in the city of Zagreb The study was performed in 2009 at the central wastewater treatment plant of the city of Zagreb. Selected illicit and licit drugs were monitored in 24h-composite samples of untreated wastewater over a period of eight months. The analytical procedures used for the determination of selected drug target residues (DTRs) included solid phase extraction and subsequent analysis by liquid chromatography-tandem mass spectrometry (LC-MS-MS). The collective consumption of a number of selected drugs, including 5 illicit drugs (cannabis, heroin, cocaine, amphetamine, MDMA) and several licit drugs belonging to therapeutic opiates and antimicrobials was estimated for the city of Zagreb, based on the representative mass loads of the corresponding DTRs, and the average excretion rates, reported in the literature. The average daily mass loads of studied DTRs varied in the range 1.6 -122 g/day. The observed mass loads were relatively uniform during the investigated period for most of the studied drugs. However, stimulating illicit drugs, including cocaine and amphetamine-type drugs, exhibited a clear weekday-dependant pattern, characterised by an enhanced consumption during weekends. The consumption of the illicit and licit drugs determined in this study was compared with the available official figures and observed agreements and disagreements were discussed
