Microplastics in total atmospheric fallout : review and monitoring in the Paris region

Abstract : Although the topic of microplastic pollution has been a source of scientific interest since 2004, microplastics in the atmospheric compartment and urban areas have only been studied for a few years. After a summary of the state of literature on the atmospheric compartment, this work compares the methods and results of the first evaluation of microplastic pollution in the Paris region to a more recent monitoring campaign conducted in 2021. In the early study, conducted by Dris and coworkers, total atmospheric fallout samples were collected in two sites in the East of the Paris region between February 2014 and February 2015. Samples were collected over periods ranging from one week to a month. Analyses focused on fibres and relatively large particles, primarily because of methodological limitations. An estimate of 2 to 355 particles/m 2 /d were measured, largely fibers. In the current work, sampling methods were kept similar to the earlier campaigns. Samples were collected over a 5 months period in 2021. Sample acquisition times varied between three and ten days, following rain events and tendencies. Samples underwent a treatment prior to analysis, and were characterized using an automated mapping-based micro-FTIR analysis. Microplastic fragments of smaller sizes were identified and quantified. Preliminary results show an estimate of ~100 particles/m 2 /d
