Post-Doctoral Research Associate in Microplastics in Archaeological Samples; CHS

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 around the U.K. as well as 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.

The laboratory aspects involve analytical geochemistry and chemistry approaches including a long term mesocosm investigation of the potential impacts of microplastics on artefacts of differing compositions.

This 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 University of York but also involving York Archaeology Trust and University of Hull. The work will deliver both cutting edge microplastics science as well as assessing the impact of plastics on archaeological preservation.

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

• Compiling and analysing datasets on microplastic concentration in waters, soils and sediments and geospatial data relevant to assessing contamination risk at archaeological sites;
• Working alongside others in the team, to decide locations for sampling based on data review and stakeholder engagement;
• Conducting sample digests, filtrations and microplastics analyses using micro-Fournier Transform Infra Red spectroscopy;
• Conducting a long term mesocosm investigation using soils and sediments spiked with microplastics;
• Working with project partners to integrate findings of laboratory mesocosms with archaeological site-based contamination risk assessments

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