Low concentrations of aromatic pollutants in marine environments complicate their analytical detection and monitoring. In the presented thesis, devices using membrane-inlet mass spectrometry in combination with a selective laser-based ionization technique were developed as a possible approach for the fast and sensitive analysis of volatile and semi-volatile aromatic pollutants in marine systems with high temporal resolution. Without prior sample preparation, the obtained detection limits are in the lower ng/L range, which allows direct detection of aromatic compounds in environmental waters.<eng>
