Department of Aquatic Sciences and AssessmentThird-cycle subject areaEnvironmental assessment, specialising in environmental chemistry.Description of the doctoral project This doctoral project aims to improve the understanding of contaminants of emerging concern in food chains by using bioaccumulation and trophic transfer as a strategy for chemical prioritisation. The project will investigate how contaminants move from environmental sources into organisms and through food chains, and how these processes can be used to identify substances of relevance for ecosystems and One Health. The project will focus on one or more selected food-chain systems, depending on sample availability, collaborations and scientific relevance.The project includes i) selecting relevant food-chain systems, biological matrices and contaminants of emerging concern based on occurrence data, chemical properties, bioaccumulation potential and available samples; ii) applying target, suspect and non-target screening using LC-HRMS to identify known and previously unknown substances in selected biological matrices; iii) assessing bioaccumulation, biomagnification and trophic transfer patterns where suitable data and samples are available; iv) using environmental specimen bank samples, where available, to investigate time trends and support retrospective screening; and v) connecting measured chemical patterns to possible environmental sources.You will work in an international, interdisciplinary team. The project provides access to advanced instrumentation and training in data analysis, scientific communication, and collaborative research.About the positionWe are seeking a PhD student who will advance the understanding of contaminants of emerging concern in food chains, with a particular focus o…DoktorandDoktorander
