Coastal regions are specific ecosystems often polluted by anthropogenic organic emissions. Organic-geochemical analysis requires a sensitive methodology, enabling detection and identification of a wide qualitative spectrum of organic compounds. Within the scope of this thesis, the coastal area of Kavala City in Northern Greece has been considered as a model region to study anthropogenic organic emissions, due to the significant local density of anthropogenic emission sources. Marine water, sediment and soil samples have been retrieved and extracted with organic solvents. The extracts have been investigated qualitatively and quantitatively by non-target screening approach based on gas-chromatography-mass spectrometry.
Such a procedure meets the requirement for detection and identification of a broad range of organic xenobiotics. Moreover, the concept of anthropogenic markers has been used in the systematization of the results for identification and evaluation of source specific contributions. The results enabled a weighing of the anthropogenic impact with respect to the marine and terrestrial environment as well as the appearance of emission hot spots. Finally, petrogenic and pyrogenic emissions in the investigated area have been determined by two different methods followed by correlation of the results.
Additionally, the investigation revealed rarely described or unknown compounds which could be clearly allocated to anthropogenic origin due to their structural properties. Information on occurrence, production and application has been compiled by means of literature research in order to assess their usefulness as source indicators.
Finally, the outcome of the investigation stresses the importance of taking rarely documented contaminants under serious consideration in monitoring programs.
