    "title": "Images of airborne particles including microplastics captured using Burkard spore traps at Hull, UK and Gqeberha, South Africa (March, July, and August 2023)",
    "abstract": "This dataset contains images of airborne particles captured by Burkard spore traps, a method commonly used for global pollen monitoring. The images can be used for the identification, characterisation, and quantification of outdoor airborne particles, including microplastics.\r\n\r\nBurkard spore traps continuously sampled air for seven days at the following times and locations:\r\n- The University of Hull, UK (53° 46’ 16.87” N; 0° 22’ 2.64” W) starting at 10:00 on 10/03/2023\r\n- The University of Hull, UK (53° 46’ 16.87” N; 0° 22’ 2.64” W) starting at 11:00 on 18/07/2023\r\n- Nelson Mandela University, Gqeberha, South Africa (34° 0'4.66\"S; 25°40'2.40\"E) starting at 13:00 on 03/08/2023\r\n\r\nTraps 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.\r\n\r\nThis dataset consists of screenshot images of airborne particles during downstream analysis with Fourier Transform Infrared (FTIR) spectroscopy, used to identify materials, in OMNIC Picta software. Low-resolution screenshots are provided because the original images are no longer available.\r\n\r\nFiles are named using the convention Burkard_City_Country_Month_DataCollectionDay_ParticleNumber.jpg, e.g.:\r\n- Burkard_Gqeberha_SA_August_1B_3.jpg\r\n- Burkard_Hull_UK_March_C4_48.jpg\r\n\r\nThis dataset was produced under Natural Environment Research Council (NERC) project 'Development of the first global standard for airborne microplastic monitoring' (grant reference: NE/X010201/1).",
