River Thames microplastic pollution study launched by University of East London
A new study examining microplastic pollution in the River Thames is underway, with researchers from the University of East London aiming to build a clearer picture of water quality across the river and provide evidence to support future environmental policy. The project, led by Dr Ria Devereux from the university’s sustainability research institute, will collect and analyse water samples from locations stretching from Teddington in south-west London to Southend-on-Sea in Essex.
Researchers say the work will help identify whether microplastic pollution levels in the Thames are changing and how environmental pressures, including storm activity, may be affecting the river system.
The Thames has previously recorded some of the highest levels of microplastics found in any river in the world, making ongoing monitoring an important part of understanding the condition of the waterway.
“The River Thames is one of the most internationally recognised urban rivers in the world, yet we are still learning about the scale and complexity of microplastic pollution within it,” Dr Devereux said. “This project is about providing robust scientific evidence that can support better environmental decision-making and help policymakers understand where interventions may be needed most.”
The research team will collect three litres of surface water from seven publicly accessible riverside locations: Teddington, Westminster, St Katharine Docks, Limehouse, North Woolwich, Tilbury, and Southend. Once collected, the samples will be filtered in a laboratory to capture microscopic particles. Researchers will then examine the filters under a microscope and record the size, shape and colour of suspected microplastics.
Selected particles will undergo further analysis using Fourier-transform infrared spectroscopy, known as FTIR, allowing scientists to confirm whether the particles are plastic and identify the material type.
The study is intended to help researchers understand how microplastic pollution levels vary along the Thames and whether those levels are increasing or decreasing over time. It will also examine how changing environmental conditions and storm events may influence the concentration of microplastics throughout the river system.
Alongside the scientific research, the project will produce policy briefings and bring together regulators, environmental organisations and policymakers through a stakeholder workshop hosted at UEL’s Royal Docks Centre for Sustainability.
