The extensive use of organic chemicals for different applications (industry, agriculture, pharmaceutical usage, etc.) leads to low-concentration but long-term exposure of the aquatic environment to their residues. The protection of our coasts and marine waters is a long-standing part of the European Community environmental policy, which is also broader internationally regulated. Various organisations involved (a.o. OSPAR, USEPA, etc.) stress the need for a more integrated, consistent and economically favourable strategy to meet legislative and international obligations. In the context of a recently started Belgian project, we are studying a relatively new approach making use of passive samplers and hybrid high-resolution mass-spec- trometry coupled to liquid chromatography for analysing known and unknown emerging organic micro-pollutants in the ma- rine environment. Amongst others, attention is given to endocrine disrupting compounds (EDCs) including steroidal hor- mones. In this particular study, we present the development and optimization of the analytical method to measure multiple steroidal EDCs. The analytes were separated on a 1.9 μm Hypersil Gold column (10 mm x 2 mm) and quantified in full-scan by a Q-Exactive benchtopTM mass spectrometer. Chromatographic variables like mobile phase flow, acidification, and column oven temperature were optimized by injecting analytical standards. By analysing sea extracts, the mass-spectrometric pa- rameters (sheath gas, auxiliary gas, sweep gas, discharge current, capillary temperature, S-lens RF, and vaporizer tempera- ture) were optimized. Next, 55 steroidal EDCs were successfully extracted from substitute ocean water. In a final step, this method will be validated and applied for the targeted analysis of steroidal EDCs in the marine environment.
