Pharmaceuticals are recognized as newly emerging pollutants and have recently gained more attention on their effects in aquatic environment. Pharmaceuticals include a hundreds of compounds which differ by their physico–chemical properties and environmental behaviour. Most of these compounds are water soluble and non-volatile, others are polar and less adsorbable, while some others are lipophilic and show a certain tendency to bioaccumulation and adsorption on suspended sediments. Increased analytical capabilities in liquid chromatography and mass spectrometry revealed that discharged pharmaceutical can easily undergo transformation in aquatic systems resulting in different molecules with contrasting effects to the ecosystem elements. Nevertheless the extent of this problem, the transport and fate of pharmaceuticals in the aquatic environment remains poorly understood.
Estuarine systems, being situated between land and marine environments, are likely important sites for pharmaceutical attenuation due to high input loads and biogeochemical activity. In shallow estuarine systems, sediments are frequently resuspended, therefore they act as an effective absorber and carrier for such contaminants, thereby affecting their long-term fate and toxicity. However, it remains unclear how pharmaceutical can effect biogeochemical processes within sediments. The aim of present PhD project is to determine transport and fate of pharmaceuticals along river-lagoon-sea continuum combining analytical, biogeochemical and mass calculations. It will reveal the extent of pharmaceutical pollution in the aquatic environment and putative effects on different ecosystem components. The project, in particularly, interests in how pollution by pharmaceuticals affect biogeochemical processes such as nitrification and denitrification which are important in mitigating eutrophication in the coastal lagoons. Finally, project is seeking to develop a simple bioassay for fast, reliable identification and quantification assessment of pharmaceuticals in estuarine samples.

Skills/Qualifications
We are looking for motivated student who holds master’s degree in a relevant field (ecology and environmental research, biogeochemistry, biology, geochemistry, chemistry, pharmacological or natural sciences). Applicant should have the interest and ability to learn new research methods as needed for attaining the tasks, should be able to work independently as well as in an interdisciplinary team; hence good communication skills are important. Good English language skills are necessary. Working experience in liquid chromatography and mass spectrometry brings advantages.
PhD student will join to the young, leading “Aquatic Biogeochemistry and Ecosystems Functioning” research group, which conducted number of studies targeting nutrient and gas cycling, mediated by macrofauna, micro- and macroalgae as well as solute transport along river-lagoon-sea continuum. Therefore, the excellence of group relies on a combination of technical and scientific know-how. The scientists from the group are continuously involved in development and application of novel tools for biogeochemical processes analysis. The group is building an international research network that consolidates interactions among scientists from different countries (Italy, Sweden, Germany, Poland, France, Denmark, USA and etc.). The thesis will be carried through the collaboration with GGF project (INBALANCE, 2017–2021) and national and EPA projects.
