Pilot study on method development of microplastic analyses

Important results from the project

In this project different methods for sampling, processing and analysis of microplastics in different matrices from different sources were reviewed and evaluated. The strengths and limitations of the methods, including methods for quality control and quality assurance, were described. Increased harmonization of these methods is crucial to ensure comparable data in different research studies but also to enable operational environmental monitoring and emission control.

Expected long term effects

The expectation is that by describing current methods for microplastics analysis and the challenges that exist with these, the project can speed up the standardization work. The project also points to the need for these standardization to be verified through inter laboratory comparisons against reference laboratories to ensure data quality and comparability.

Approach and implementation

The project was implemented as a literature study where IVL systematically investigated relevant scientific literature. While the project group included senior researchers in both polymeric materials and optical- and analytical methods for detecting microplastics, knowledge base and external experts could be effectively identified. Project staff also interviewed external experts and participated in microplastics seminars for knowledge building. The project plan and budget have been followed.
