Microlitter particles in water surface sampled with ferrybox in Danish waters 2019 - 2020

In a pilot study, microlitter was sampled with a Ferry Box system on the commercial ferry (M/S Color Line Fantasy) between Oslo and Kiel. The system acquired samples in the Danish part of the Skagerrak and Kattegat. In total thirteen samples were collected from September 2019 to February 2020 using mesh sizes 100 and 500 µm. Eleven samples were successfully processed. The samples were subsequently processed and analysed for chemical composition using FTIR. Microplastic amounts found ranged from 0 to 1.85 fragments or fibers per m3 (average 0.71 per m3).
