Assessing human exposure to emerging contaminants using high-resolution MS

SVERIGES LANTBRUKSUNIVERSITET

Department of Aquatic Sciences and Assessment Third-cycle subject area Environmental 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 position We are seeking a PhD student who will advance the understanding of contaminants of emerging concern in food chains, with a particular focus on bioaccumulation, trophic transfer and advanced chemical screening. To achieve this aim, you will develop and apply analytical workflows for the detection and identification of known and previously unknown compounds in complex biological matrices, including sample preparation, extraction and clean-up strategies. The project will also include semi-quantitative analysis of detected compounds and the assessment of bioaccumulation, biomagnification and trophic transfer patterns in selected food-chain systems. Where suitable samples are available, environmental specimen bank material may be used to investigate time trends and support retrospective screening. The duties also include preparation of biological and environmental samples, extraction and analysis of target and non-target compounds, processing of large HRMS datasets, data analysis, statistical evaluation, interpretation of chemical patterns in relation to environmental sources, collaboration with national and international partners, and scientific manuscript writing in English. Requirements To meet the general entry requirements you must have been awarded a second-cycle (Master’s) qualification, satisfied the requirements for courses comprising at least 240 credits of which at least 60 credits were awarded in the second-cycle, or acquired substantially equivalent knowledge in some other way in Sweden or abroad (Higher Education Ordinance 1993:100, Chapter 7, Section 39). Specific entry requirements for the third-cycle courses and study programme in environmental assessment, specialising in environmental chemistry. To meet the specific entry requirements, you must have knowledge of aquatic ecology, aquatic biogeochemistry, statistics or ecotoxicology. The undergraduate degree must include a degree project.  You must also meet the equivalent English language requirements as those necessary for the Swedish upper-secondary qualification Engelska B/6. Your profile Applicants shall hold an MSc in analytical chemistry, environmental chemistry, chemistry, ecotoxicology, environmental science, food science or equivalent. Specialisation in chemical analysis of organic contaminants and experience with LC-MS, LC-HRMS, GC-MS or other advanced mass spectrometry techniques are valuable merits. Experience with suspect and non-target screening workflows is highly desirable. Previous experience with chemical analytical laboratory work, particularly involving complex biological, food, biota, soil or sediment matrices, is advantageous. Knowledge of contaminants of emerging concern, bioaccumulation, biomagnification, trophic transfer or time-trend analysis is considered a merit. Data processing skills using statistical computing, visualisation and data analysis tools (e.g. R, Python or similar) are also considered a merit. Emphasis is also placed on personal characteristics such as strong interpersonal skills, analytical and problem-solving abilities, accuracy, motivation, and the capacity to work independently as well as in collaboration with others.

Department of Aquatic Sciences and Assessment Third-cycle subject area Biology Description of the doctoral project   Antimicrobial resistance (AMR) is one of the most pressing global health challenges of our time. A key driver of AMR spread is the horizontal transfer of antibiotic resistance genes via conjugative plasmids — mobile genetic elements that move between bacteria. Plasmid-dependent phages (PDPs) are viruses that specifically infect bacteria carrying these plasmids, making them a potentially powerful but largely overlooked tool in controlling resistance gene transmission. This PhD project is part of ECOPHARM, a research project funded by the Knut and Alice Wallenberg Foundation (Wallenberg Academy Fellows 2025) and is based at the Department of Aquatic Sciences and Assessment, SLU Uppsala. The overarching aim of ECOPHARM is to decipher the mechanisms driving PDP interactions with conjugative plasmids and bacterial hosts, and to understand their impact on antibiotic resistance gene transmission in aquatic environments. As a PhD student, you will investigate the diversity, ecology, and functional interactions of plasmid-dependent phages in aquatic ecosystems. The work will combine environmental sampling, cultivation-based approaches, metagenomics, genome analysis, and experimental infection assays. You will work in a dynamic and internationally connected research environment at the intersection of microbial ecology, virus-host coevolution, and AMR research. To learn more about our research you can check out our webpage https://www.bionomics-mmlab.com/ About the position The PhD student will be expected to: Design and carry out field sampling of aquatic environments to characterize PDP communities Perform laboratory experiments to study PDP–plasmid–host interactions under controlled conditions Apply metagenomic and bioinformatic tools to analyze microbial and viral community data Contribute to experimental work on phage isolation, cultivation, and infection assays Present findings at lab meetings, national and international conferences, and contribute to scientific publications Adhere to lab policies on data management practices Communicate progress and bottlenecks timely and clearly Collaborate with national and international project partners within the ECOPHARM network Requirements To meet the general entry requirements you must have been awarded a second-cycle (Master's) qualification, satisfied the requirements for courses comprising at least 240 credits of which at least 60 credits were awarded in the second-cycle, or acquired substantially equivalent knowledge in some other way in Sweden or abroad (Higher Education Ordinance 1993:100, Chapter 7, Section 39). Specific entry requirements for the third-cycle courses and study programme in biology. To meet the specific entry requirements, you must have at least 90 HEC in biology-related subjects. This must include a degree project and at least 30 HEC must be at second-cycle level.
