Fine micro- and nanoplastics concentrations in particulate matter samples from the high alpine site Sonnblick, Austria.

We report atmospheric fine micro- and nanoplastics concentrations from particulate matter (PM) samples of two size fractions (PM, fine micro- and nanoplastics, and PM, nanoplastics), which were collected at the remote high alpine station Sonnblick Observatory, Austria. Active sampling was performed from June 2021 until April 2022. Analysis was done using TD-PTR-MS to detect 6 different plastic types.
