This 30‑month PDRA position in microplastics and geochemistry at the University of Lincoln seeks to understand the presence of microplastic contamination in archaeological sediments from sites across the U.K. and their impacts on selected artefacts. The successful candidate will lead a blended field‑ and laboratory‑based research project quantifying the levels and types of plastic polymers in selected archaeological samples. Laboratory work includes analytical geochemistry and chemistry approaches, including a long‑term mesocosm investigation of the potential impacts of microplastics on artefacts of differing composition.

The project is part of the wider AHRC-funded ‘Micro Past’ Project, Challenging the Preservation Paradigm:
The Impact of Microplastics on the Integrity of Archaeological Soils and Sediments, co‑ordinated by the University of York and involving the York Archaeology Trust and the University of Hull. The work will deliver both cutting‑edge microplastics science and an assessment of the impact of plastics on archaeological preservation.

The PDRA will be a member of research groups within the School of Natural Sciences and will work closely with colleagues from across the universities and the wider project partner network.

• Compile and analyse datasets on microplastic concentration in waters, soils and sediments and relevant geospatial data to assess contamination risk at archaeological sites.
• Collaborate with team members to decide sampling locations based on data review and stakeholder engagement.
• Conduct sample digests, filtrations and microplastics analyses using micro‑Fourier Transform Infrared spectroscopy.
• Lead a long‑term mesocosm investigation using soils and sediments spiked with microplastics.
• Collaborate with project partners to integrate laboratory mesocosm findings with archaeological site‑based contamination risk assessments.

The PDRA will also lead the production of high‑quality research outputs, including presentations, reports, papers and other publications of national and international standing.
