Summary of Results

During the initial phaseof the project a new method vor QUEChERS bsed muliticompound analysis of relevant pharamceuticals was developed as a part of a still ongoing Masters project at NMBU/UNIS (Siri Havstein Aspnes). The method validation, 2.5 L sewage water from the outlet of Longyearbyen (Svalbard was collected in June 2015). The Water samples were extracted with a already established high volum solid phase method on HLB columns (WATERS, Milford, CA)  after filtration (Whatman, GF/C 24 mm, 1.2 um pore). Aliquots of 2 sewage water samples and one blank samples are currently analysed for the following substances at NMBU, NORUD and evt. NILU:  Metronidazole, Ciprofloxacin, Ketoprofen, Trimetoprim, Prednisolone , Sulfamethoxazole , Tetracycline, Penicillin G; 13C3 koffein is used as Internal. standard. In addition, the following substances are purchased as stanards for the extention of the method after a QUEChERS apporach is established during winter 2015/2016: Ethinyl Estradiol, Atorvastatin, Acetgyl Salicylcic acid, Simvastatin, Metoprolol, Lorsatan, Amlodipine, Zopiclone as well as 13C-Ibuprofen as additional Internal standard.

The method currently under development is based on the study by Cerquerira et al. (Cerqueira M.B.R., Guiherme J.R., Caldas S.S., MArtins M.L:, Zanella R., Primel E.G. (2014) Evalaution of QuEChERS mehod for the extraction of pharmaceuticals and personal care products from drinking water treatment sludge with determination by UPLC-ESI-MS/MS. Chemosphere 1007:74-82.) The method will be available for application in early spring 2016.

Plans for 2015: Representative samples from three Arctic locations (Effluent, influent and biota) will be collected from three Norwegian Arctic settlements/ towns: Tromsø, Longyearbyen, Kirkenes.T he QuEChERS based method will be applied and distribution profiles will be determined. The method will be refined and implemented into the analytical  programs of NORUD, NILU and NMBU. A first environmental toxicological study will be performed in close collaboration with our Russian partners from SRCES RAS). Preferably, the study will be performed as MSc project in close collaboration with all partners involv ed.

For the Management

Currently the focus of the initial year is laid on chemical analysis. We expect, that the entire project group will be involved during the application and sample collection phase in 2016.

Conclusions

The project is planned as a pilot study specifically aiming at validating methods for characterization of biochemical transformation processes and assessment of environmental effects.A QuEcHERS based multi compound analysis method is currently under development and will be applied in sample materias (Sewage, effuent, biota) from three Arctic locations. The filed work is planned for 2016.
