Summary

Researchers applied pyrolysis-GC/MS to distinguish between different commercial polyesters in microplastic fibers — including those labeled generically as '100% polyester' in consumer products such as toys, bedding, and carpets — to improve the specificity and standardization of microplastic reporting.

Microplastic fibers, defined as synthetic polymer fibers between 1 µm and 5 mm in length, are a significant source of microplastic pollution. Consumer products such as stuffed toys, bedding, carpets, curtains, and clothing are often made of material labeled "100 Also see: https://micro2024.sciencesconf.org/559006/document
