From March 14th to March 27th 2021, researchers from CNR-ISMAR participated in the scientific cruise “PoPlast2021” on board the Italian research vessel “G. Dallaporta”.  The cruise was performed in the Northern Adriatic Sea and focused on the quantification of macro and micro-plastic pollution in front of the Po river delta. The scientific activities during the cruises were disseminated to primary school students through a series of live streaming events, which allowed the students to ask questions to the researchers on board the ship.
