Adapting Methods for Isolation and Enumeration of Microplastics to Quantify Tire Road Wear Particles with Confirmation by Pyrolysis GC-MS.

ABSTRACT: The complex, varied composition (i.e., rubbers/elastomers, carbon black, fillers, additives, and embedded road materials) and wide density range of tire road wear particles (TRWPs) present challenges for their isolation and identification from environmental matrices. Reliable quantification is important for understanding the environmental fate and potential adverse effects of TRWPs. To address environmental monitoring needs, the present work adapts a series of isolation and identification steps from methods commonly applied for microplastic analysis for single-particle-level enumeration of TRWPs from environmental samples. We present the method performance of a two-stage density separation with saturated NaCl and sodium polytungstate to isolate TRWPs from sediment matrices, the compatibili
