Analysis techniques for quantifying nano-and microplastic particles and their degradation in the marine environment (ANDROMEDA) (Analysis techniques for quantifying nano-and microplastic particles and their degradation in the marine environment)

Current methods for microplastic (MP) analysis can be divided into low-cost versus more advanced methods. ANDROMEDA recognizes that further development and validation is needed for both approaches. Low-cost methods are needed to identify a broad range of MP polymers. Advanced methods need further development to push the limit of detectability for smaller sizes of MP and nanoplastics (NP). Within ANDROMEDA, in situ MP detection, efficient sampling and cost-effective laboratory methods will be optimized to. Approaches will be based on hyperspectral imaging, chemical markers and fluorometric detection techniques to quantify and characterize MP and NP down to 1 µm, 0.2 µm or lower. Specific tasks will focus on challenging types of MP such as microfibers, tire wear particles (TWPs) and paint flakes. Quality assurance will be a central theme in all aspects of the project. Communication and data management will ensure strong stakeholder involvement and outreach of the project results.
