About the Project
This project is one of a number that are in competition for funding from the Red-ALERT CDT for entry in September 2025.
Overview of the Research:
This PhD project investigates the ecological impact of traffic-related microplastics pollution, particularly tyre rubber and its additives, on small rivers in the UK. Focusing on the Cam and Wellow catchment areas, with potential expansion to other regional priority sites, the study aims to address a critical knowledge gap. While recent US and EU research has shown that antioxidant additives like 6PPD from tyre rubber particles cause fish mortality in small rivers, their effects on UK catchments remain largely unknown.
The project’s primary objectives include identifying pollution hotspots during heavy rainfall events, comparing traffic-related pollution risks to other ecotoxicological threats, assessing the ecological impact of tyre rubber additives on small river ecosystems, and developing recommendations for interventions and best practices. Initially, priority highway drainage discharge sites and high-risk areas for traffic-related aquatic pollution will be identified. This will be followed by establishing comprehensive sampling and analysis protocols for water, sediment, and ecological surveys, considering seasonal variations in rainfall and contaminants.
Data collection will involve sampling at both priority and less polluted sites, analysing for microplastics, tyre rubber particles, and associated additives. River corridor surveys will be conducted to evaluate the relationship between traffic-related pollution and ecological health.
This project will significantly enhance the understanding of traffic-related chemical and microplastic pollution in UK river systems, aligning with priorities of local authorities and regional partners. Expected outcomes include a comprehensive assessment of tyre rubber additive risks in small UK rivers, identification of pollution hotspots, and best practice guidelines for road design and retrofit run-off management schemes.
The PhD training covers environmental science and ecology, focusing on rivers, soil, and sediments; chemical and microplastic analysis; field research and data management, including sampling strategies and large dataset analysis; urban engineering, flooding and run-off management; knowledge of environmental regulations; and communication skills, encompassing presentation skills and scientific writing.
This project exemplifies interdisciplinary research, bridging Environmental Science, Ecology, Environmental Analysis, and Urban Engineering, while incorporating Environmental Legislation. Led by a diverse team of supervisors, each representing a distinct discipline, the study integrates multiple fields to address complex environmental challenges comprehensively.

Candidate Requirements:
Applicants should hold, or expect to receive, a First Class or good Upper Second-Class UK Honours degree (or the equivalent) in a relevant subject. A master’s level qualification would also be advantageous.
This PhD project is ideal for students with a strong background in Environmental Science, Environmental Chemistry, Analytical Chemistry, Ecology, or Environmental/Chemical Engineering. Candidates from related disciplines with relevant expertise are also encouraged to apply. Practical experience in environmental fieldwork and/or laboratory techniques is highly desirable. The interdisciplinary nature of this research provides an excellent opportunity for candidates to apply and expand their skills in a cutting-edge environmental research project.
*Non-UK applicants must meet the programme’s English language requirement prior to a formal offer being made.
