Release and Transformation of Polymer-Associated Chemicals from Aged Polypropylene and Polyurethane Microplastics in Freshwater Laboratory and Mesocosm Studies
Microplastics (MPs) release polymer-associated chemicals (PACs) into aquatic environments, yet their environmental release, transformation, and persistence remain poorly understood. We applied nontargeted liquid chromatography high-resolution mass spectrometry to characterize PACs released from polypropylene (PP) and...
