WE TAKE ACTION BY COMBINING
engadine, switzerland 2021
Up to 14,000 tons of plastic end up in Swiss soil and water every year. Initial studies carried out in Swiss lakes and rivers showed that microplastics were found in each of the examined water and sediment samples.
More recent studies have even shown the presence of microplastics in snowfall in Swiss mountain regions, which would be an indicator of atmospheric transport and subsequent microplastic deposition.
The aim of this study is to provide the first detailed evidence of microplastics (> 0.1mm) in the waters of the Upper Engadine at 1820 meters above sea level.
In general, studies on microplastic measurements are carried out as time-limited measurements (snapshots).
Therefore, for our study, samples are taken weekly at the same locations for a period of two months in order to obtain the most accurate picture possible with regard to the occurrence, quantity, size and type of the microplastic.
This planned project will be the first Alpine study of its kind, serving to track the changes in microplastic presence in Alpine waters over a period of time.
The Azores are a remote group of islands in the Atlantic at the very edge of the North Atlantic Gyre.
This expedition will be the second of its kind and a follow up expedition to our expedition in 2019, which was the first one ever that has been conducted in the Azores, allowing us to predict and monitor the amount of microplastics in this remote area.
In order to obtain the most accurate picture possible, detailed data on the quantity and composition of the materials found there is needed.
