          <gmd:abstract>
            <gco:CharacterString>Burkard Spore Traps, commonly used for global pollen monitoring, were used to capture airborne particles, allowing the subsequent identification, characterisation and quantification of outdoor airborne particles including microplastics.

Burkard traps continuously sampled air for 7 days from the University of Hull (UK.) (53° 46’ 16.87” N; 0° 22’ 2.64” W) at 10:00 on 10/03/2023 and 11:00 on 18/07/2023 respectively, and Nelson Mandela University, Gqeberha (SA). 34° 0&#x27;4.66&quot;S; 25°40&#x27;2.40&quot;E starting at 13:00 on 03/08/2023. Traps were on flat roofs with the sampling orifice at least 1 m above the surface and at least 2 m away from the building edge.

Tape adhesive was glycine jelly and an oxidative digest using 30% hydrogen peroxide was performed to remove organic mater. This dataset contains screenshot images of airborne particles during downstream analysis with Fourier Transform Infrared (FTIR) spectroscopy, used to identify materials.</gco:CharacterString>
