Get to know... Dércia Santos

My scientific research focuses on aquatic ecotoxicology, particularly on how emerging contaminants affect aquatic species. My academic path has been closely connected to the University of Trás-os-Montes and Alto Douro (UTAD), where I completed a degree in Genetics and Biotechnology, followed by a master’s in Biotechnology for Health Sciences. My master’s thesis, which evaluated the effects of endocrine-disrupting pollutants on zebrafish (Danio rerio) embryos, marked the beginning of my engagement with environmental and aquatic sciences. In 2022, I obtained my PhD in the International Doctoral Program in Marine Science, Technology, and Management (Do*Mar), and in collaboration with the Spanish Institute of Oceanography–Oceanographic Center of Vigo (IEO-CSIC), I focused may research on the combined effects of microplastics and metals in zebrafish (Danio rerio) and blackspot seabream (Pagellus bogaraveo), setting the stage for future research on the biological impact of plastics on fish health and how it can affect aquaculture and fisheries sustainability.  

Throughout these years, I continued to work extensively on assessing and understanding the toxic effects of microplastics - an emerging and pervasive pollutant - on fish fitness, survival, neurodevelopment, and reproduction. 

My research interests include deepening our understanding of the ecological consequences of emerging contaminants and contributing to the development of more effective strategies for ecosystem protection and sustainable management. Ultimately, my work aims to underscore the urgent need for environmental monitoring, informed policy interventions, the adoption of sustainable practices, and a transition toward a circular economy that reduces pollutant inputs into aquatic environments.
