Zusammenfassung: | Endocrine disrupting chemicals (EDCs) are of growing concern in aquatic ecosystems due to the potential of modulating the endocrine system in aquatic species by interfering with reproduction and developmental processes. Bisphenol-A (BPA) belongs to the EDCs and has been documented to induce estrogenic effects in fish. This study aimed to develop a reliable method based on molecularly imprinted polymers solid phase extraction (SPE MIPs) and LC-MS/MS for the analysis of BPA in liver and muscle samples in invasive round goby Neogobius melanostomus sampled in the river Rhine in Basel, Switzerland. Additionally, all fish samples were analysed for the liver protein vitellogenin to provide an unspecific indication of EDC induced endocrine effects. The study also aimed to investigate any sex- and size-specific differences in BPA contamination and the overall condition of the target species, by documenting condition indicators including total length, total weight, liver weight and hepatosomatic index (HSI). BPA contamination of the sampled round goby was below limit of quantification. A further improvement of the method is needed to detect low contaminations especially in liver samples, where high matrix interferences occurred. Vitellogenin measurements indicated the presence of EDCs. |
