Year: 2020
Project manager: Vladimir Nikiforov
Project code: 533 802019

The aim of the project is implementation of commercially available fully deuterated polymers as Internal Standards for analysis of Micro- and Nanoplastic.
The project will employ the most advanced instrumental methods for detection, identification and quantification of nano- and microplastic: Pyrolysis-GC-Orbitrap-MS, Hydrolysis-GC/LC-Orbitrap-MS and 2D/3D Raman- and FTIR-microscopy. For the first time Deuterium labeled polymer microparticles, made by the applicants from commercially available deuterated polymers, will be used as internal standards for analysis of micro/nanoplastic. The advantage of Deuterium labelling is its applicability for both mass- and vibrational spectroscopy.
The project focus is on QA/QC in the quantitative analysis for small micro- to nanoplastic particles, similar to standard procedures in the analysis of ultra-trace organic contaminants, and in making improved techniques available to the Fram Centre community and worldwide.
Year 1: Application of two already prepared deuterated polymers, polymethylmetacrylate and polystyrene (PMMA-d8 and PS-d8) in currently employed methods within on-going projects. Reporting at major international symposia (DIOXIN, SETAC, MICRO-2020).
Year 2: A Workshop will be organized in the Fram Centre for members and wider audience for dissemination of gained insights and developed method(s). Peer-reviewed publication(s).
The requested funding will complement existing larger projects and stimulate use of D-labeled polymer standards, harmonization of analytical methods and dissemination of the results.
The international partner, a leading group in Raman Microspectroscopy, Surface-enhanced Raman Scattering and Stable Isotope Raman Microspectroscopy is a critical asset of the project. Together, the partners combine the major recommended microplastics quantification methods of highest standard.
