Hub researchers have developed a practical framework to improve how micro and nanoplastics are detected and measured in the environment. The work provides clearer guidance for scientists and stronger evidence for policy and regulation.
Microplastics and nanoplastics are now found in water, soil and air. Yet measuring them accurately remains a major scientific challenge. Differences in laboratory methods can produce inconsistent results, making it difficult to compare studies or assess risk with confidence.
Research supported by the Sustainable Communities and Waste Hub addresses this gap through a new analytical toolkit.
Bringing methods together
The toolkit reviews and evaluates a wide range of laboratory techniques used to detect and characterise micro and nanoplastics. It examines:
- Mass-based methods that identify plastic types through chemical signatures
- Microscopy and spectroscopy approaches that count and classify particles
- Separation techniques that isolate particles by size and density
By comparing strengths and limitations, the research shows how combining methods can produce more reliable and comprehensive data.
Supporting better policy and practice
Consistent measurement underpins effective environmental regulation. This work:
- Improves comparability of data across studies
- Highlights gaps in quality assurance and reference materials
- Provides a roadmap for more standardised monitoring
Stronger analytical foundations will support risk assessment, waste policy and pollution management.
Informing future research
The study also identifies priorities for next-generation tools, including automation and improved detection of very small particles. These advances align with the Hub’s focus on generating practical, policy-relevant evidence to address emerging waste and pollution challenges.
By strengthening how micro and nanoplastics are measured, the research helps build the scientific base needed to guide sustainable communities and waste management decisions
