Research Unit

At the Unit for Contaminant Chemistry we study all aspects of the occurrence of pollutants in the environment.

Areas of particular focus include:

Discovery of new contaminants
Understanding chemical, physical and biological pathways of contaminants
Development of novel tools and techniques

We strive to synthesize scientific understanding about:

Sources
Transport
Transformation
Bioaccumulation
Pharmacokinetics of environmental contaminants

These are integrated into mathematical models that inspire new scientific hypotheses and support environmental decision-making.

Project Description

Per- and polyfluoroalkyl substances (PFAS) are widely used in healthcare due to their unique properties. However, their extreme persistence and potential health and environmental impacts have created an urgent need to understand where PFAS are used, why they are used, and whether safer alternatives can meet essential performance requirements.

As part of the PFAROS Innovative Health Initiative (IHI) consortium, this project will:

Map PFAS uses in the healthcare sector using:Determine functional requirements driving PFAS selection
- Literature review
- AI-assisted data mining
- Search methods
- Stakeholder engagement
Identify alternatives using function-based substitution principles and PFAROS data resources
Conduct alternatives assessments integrating:Develop recommendations for PFAS substitution in healthcare
- Hazard
- Exposure
- Technical performance
- Full life-cycle impacts
Identify near-term replacements and research gaps

The student will work closely with PFAROS partners across academia and industry and gain experience in alternatives assessment and regulatory-relevant research supporting Europe’s transition toward safer healthcare materials.
