“…This study investigates the autofluorescence properties of four commonly used types of polymers that are often found in the atmosphere as MPs: 36,57–62 PET, PP, PE and PS. We used pure samples (>99.9%) of PET, PP and PE as fine powders purchased from Nanochemazone (Canada), denoted by the superscript “a” and more realistic self-fabricated MP samples from everyday packaging products via a cryo-milling procedure, denoted by the superscript “b”.…”

The rapid spread and accumulation of microplastics (MPs) in environmental ecosystems result from extensive plastic usage. MPs have been found in both indoor and outdoor air. Outdoor MP levels vary widely across global cities, with reported ranges from 36 to 118 MPs m−2 day−1. However, differing measurement units complicate comparisons. Indoor MPs are particularly concerning due to the significant amount of time people spend indoors. For instance, MP concentrations in workplaces like reception areas and nail salons were found to be 309 ± 214 and 46 ± 55 MPs m−3, respectively. Technological limitations hinder the identification of MPs, with methods like µ-ATR-FTIR, µ-FTIR, and µ-Raman identifying MPs of different sizes. MPs smaller than 0.3 µm pose a health risk as they can be internalized in lung cells, while MPs larger than 10 µm are too large to enter alveolar macrophages. This review highlights the current understanding of airborne MPs, focusing on their sources, transport, and deposition mechanisms. It aims to provide a foundation for further studies to deeply assess the presence, abundance, and occurrence of MPs in aerosols, a subject that remains underexplored.
