About the position

The Department of Plant Science, Faculty of BioSciences at the Norwegian University of Life Sciences (NMBU) has a vacant three-year PhD-position with the project title “PFAS Pollution as a Threat to Safe Food: Understanding PFAS dynamics in vegetables - Uptake, Translocation, and Physiological responses". The PhD-student will be connected to the NFR financed project “PFAS in Agriculture: Risks and Mitigation (PFARM)" led by NIVA (2026-2029). One important aim of the PFARM-project is to make a risk assessment for PFAS for Norwegian conditions. The data from the PhD-student will focus on the understanding of uptake mechanisms of PFAS and lay the foundation for the risk assessment that will primarily be done by NIVA.

Per‑ and polyfluoroalkyl substances (PFAS), often referred to as “forever chemicals" due to their persistence and tendency to bioaccumulate, represent a growing global concern. Their accumulation in water, soil, biota, and plant‑based foods poses a significant threat to food safety. This PhD project will generate new insights into PFAS behavior under Northern environmental conditions and in vegetable species relevant for Northern food production.

The primary objective is to characterize PFAS uptake patterns in selected vegetable crops and to identify the key factors governing these patterns, including climatic conditions, soil properties, and plant species or organ specificity. Targeted PFAS analyses will be carried out using high‑resolution LC/QTOF mass spectrometry at the NIVA laboratory to determine PFAS concentrations in plant tissues. Additionally, the project will investigate plant physiological responses to PFAS exposure, including growth, photosynthesis, and protective mechanisms.

The applicant is made aware that an application for a PhD position at NMBU is at the same time an application for admission to a PhD programme at the institution. The documentation that is necessary to ensure that the admission requirements are met must be uploaded as an attachment.

Main tasks

Conduct controlled-environment experiments using different vegetable species and varying climate and soil conditions.
Perform growth analysis and gas‑exchange measurements to assess photosynthesis, transpiration, and overall plant performance.
Analyze plant samples for PFAS using high‑resolution LC/QTOF mass spectrometry.
Carry out metabolite profiling to gain physiological insight into how food plants respond to PFAS exposure.

The successful candidate is expected to enter a plan for the progress of the work towards a PhD degree during the first months of the appointment, with a view to completing a doctorate within the PhD scholarship period.

Competence

The successful applicant must meet the conditions defined for admission to a PhD programme at NMBU. The applicant must have an academically relevant education corresponding to a five-year master's degree with a learning outcome corresponding to the descriptions in the Norwegian Qualification Framework, second cycle.
