EEA/Norway Grants Programme LV05 NORWEGIAN-LATVIAN RESEARCH COOPERATION ACTIVITY Establishing of the Scientific Capacity for the Management of Pharmaceutical Product Residues in the Environment of Latvia and Norway NFI/R/2014/010 3

NO-LV RESEARCH COOPERATION ACTIVITY Research Project NFI/R/2014/010 Overall objective of the Project is 1) to enhance the growth of research-based knowledge 2) through the scientific cooperation between Norway and Latvia, 3) developing a scientific capacity for the administration of pharmaceutical residues in the Latvian and Norwegian environment 4

Project Background and Justification Continuous increasing consumption of pharmaceutical products (PP) PP residues are introduced into the aquatic environment from: – municipal treatment plants – hospital effluents – livestock farming – households PP presence in the environment - a serious threat to environment and human health – antibiotics  resistant bacteria strains – hormones  endocrine disrupting effects 5

Publications on Occurence of Pharmaceuticals in the Environment 6 Journal of Hazardous Materials 175 (2010) 45–95

Project Concept The knowledge about PP, their short and long- term environmental impacts, possible degradation mechanisms and management strategies is essential Advanced high resolution liquid chromatography - mass spectrometric method will be developed to obtain information about the PP contamination status 7

The Aim of the Study To develop and validate an ultrasensitive and selective analytical method for combined quantitative analysis of pharmaceuticals in the environmental water samples Ultra-High Performance Liquid Chromatography coupled to a hybrid quadrupole Orbitrap mass spectrometer (UHPLC- q-Orbitrap) will be used together with on-line sample preparation (SPE) Results obtained in Riga and Oslo will be compared 2-3 Peer-reviewed publications on analytical performance and application advantages of the elaborated method 8
