Περιγραφή
The occurrence, removal, mass loading, seasonal influence and environmental risk assessment of nine psychiatric
pharmaceuticals and four of their selected metabolites, were studied in one hospital and one urban wastewater
treatment plant (WWTP) in Ioannina city, in northwestern Greece, providing information about the efficiency of
the plants and their contribution into the final receiver's flow. Samples were collected from the influents and the
effluents of the plants in different sampling campaigns, from July to December 2016. Analytical methodology was
based on ultra-high performance liquid chromatography-Orbitrap high-resolution mass spectrometry, after
solid-phase extraction through Oasis HLB cartridges. Concentrations in both WWTPs ranged between bLOQ
and 1126.3 ng/L in the influents and between bLOQ and 1127.4 ng/L, in the effluents. Results indicated that
venlafaxine and its metabolite O-desmethyl venlafaxine were the most frequently detected compounds in the in fluents and the effluents of both WWTPs. Metabolite to parent compound ratio ranged in the influents between
0.01 and 87.2 while in the effluents between 0.01 and 47.7. Based on mass loads in the influents, venlafaxine is
consumed in high amounts (up to 67.1 mg/day/1000 inhab.), and consequently its metabolite O-desmethyl
venlafaxine (up to 139.1 mg/day/1000 inhab.). Similarly to the influents, environmental emissions, were also
higher for venlafaxine and O-desmethyl venlafaxine (10.1 and 13.3 mg/d/1000 inhab., respectively). Removal ef ficiencies in the hospitalWWTP ranged from −100% to 98.9%, while in the city WWTP from −49.9% to 99.8%. Fur thermore, an important outcome was the evaluation of the potential ecotoxicological risk, by means of risk
quotients (RQs), where none of the target psychiatrics or their metabolites showed RQ above 1.
