Curriculum
Steve Huysman was born on 5 March 1992 (Bruges, Belgium). He obtained a Master of Science in Chemical Engineering Technology at Ghent University, Belgium in 2015. Shortly after his graduation, Steve was employed as a PhD student at the Laboratory of Chemical Analysis, Faculty of Veterinary Medicine, Ghent University. His doctoral research was funded by the Belgian Federal Science Policy Office, in light of the NewSTHEPS project. In May 2018, he was granted the opportunity for a 4-week research stay at the faculty of Molecular Bioscience at Queen’s University Belfast, United Kingdom. Steve Huysman is author and co-author of 7 journal articles, and contributed to several national and international conferences. In 2019 Steve obtained his certificate of the Doctoral School of Life Sciences and Medicine.

Korte beschrijving

Nowadays, a growing societal and scientific concern exists regarding the widespread occurrence of potential endocrine disrupting compounds (EDCs) in the aquatic environment. The most important potential EDC classes comprise the steroid hormones, plasticizers and plastics additives. Indeed, even at very low concentrations, steroidal EDCs may affect the hormonal system of aquatic organisms, while leaching of plasticizers and plastics additives into the aquatic environment is inevitable as a result of their extensive use in numerous applications. Until now, limited knowledge was available on the presence of steroidal EDCs, plasticizers and plastics additives in the marine environment. Therefore, an urgent need existed to monitor the fate and effects, as well as the environmental and human risks posed by these emerging micropollutants in marine ecosystems. Given our lack of knowledge on the occurrence of EDCs, the main goal of this dissertation was to investigate the prevalence of steroidal EDCs, plasticizers and plastics additives in the marine environment. To this end, new analytical methods targeting a broad range of compounds (n=97) were developed, optimized and validated. Not only instantaneous sampling techniques were examined, but also novel long-term sampling techniques were investigated (i.e.: active and passive sampling). Both were applied extensively in the Belgian Part of the North Sea (BPNS), from 2016 to 2018. Finally, the potential negative effects of the detected concentrations were assessed.
