Abstract:
As a result of a 3-year program to improve analytical methods utilizing Py-GC/MS to measure atmospheric microplastics (AMPs) on particulate matter (PM) air filters, we report on the experimental aspects that need to be carefully considered to ensure reliable measurements. PM filter issues such as sampling methods, filter selection, pretreatment, storage, and removal of interfering organics and inorganics from sampled PM filters are presented. The impact of these issues on identification and quantification of AMPs by Py-GC/MS and their mitigation are discussed. PM filters of various sizes, i.e., TSP, PM10, and PM2.5. were sampled in Tokushima, Osaka, and Koriyama Japan.
