In this, the second newsletter from the PlasticsFatE project (www.plasticsfate.eu) you can find out how the team has been especially busy with selecting and providing a panel of relevant and representative test materials (polymers with various sizes, shapes, surfaces, ages etc.) to test the performance and applicability of available methods to MNPs, including sample preparation, physicochemical measurement, biological assays, fate modelling, and to adapt and develop them further, where needed. On page 11, you can read about and access our first policy brief in which the five MNP projects have come together to translate science into policy-relevant data. This issue also describes our engagement with other initiatives, recent and forthcoming activities and events, and provides links to all our publications so far.
