Spectroscopy of Marine Microplastic – qualitative and quantitative approach, interface characterization, selected case studies and main challenges
AI summary Read the abstract
Researchers presented outcomes from spectroscopy studies of marine microplastics including polar regions, food web transfer experiments, and complex matrix identification. The multi-site approach demonstrated how spectroscopic techniques can characterize microplastics across diverse environmental and biological contexts.
This talk presents the main outcomes of a few research case studies, for instance, marine microplastic in polar regions of Svalbard and Falklands, transfer in a food web, ecotoxicity of debris with different morphology, plastic tide in the Mediterranean, feasibility of identifying MPs in complex matrix, ghost nets recycling, primary microplastics impact and their presence in ground fishbaits. All issues will be shown from the spectroscopist's perspective. The aim is to focus on the material aspect, surface morphology of synthetic materials, leakage of added compounds, and underly the possibilities offered by spectral analysis. The main challenges and opportunities related to FTIR and Raman spectroscopy will be discussed shortly. In particular, a comprehensive overview of the proposed numerical description parameters and quantification of spectral signals will be considered. One of the aims of this paper is to open a discussion on future steps to go from simple polymer identification to the monitoring of structural changes and weathering that highly influence an overall ecotoxic effect of materials. Finally, the process of ageing and its quantification strategies will be presented.
