Fig. 3: Polymer types of microplastics normalised by number of stations within surface and subsurface samples for different water masses.
From: Microplastics distribution in the Eurasian Arctic is affected by Atlantic waters and Siberian rivers

Plastic types are listed from the lowest density to the highest density: polyethylene (PE), polypropylene (PP), polystyrene (PS), polyamide (PA), Acryl (fibres), polyurethane (PUR), others (nitrile butadiene rubber (NBR), styrene acrylonitrile resin (SAN), polyoxymethylene (POM), poly(2,6-diphenyl phenylene oxide) (PPPO), and phenoxy resin), Polyester (fibres), polyvinyl chloride (PVC) and Polytetrafluoroethylene (PTFE).
