Title of dataset | Microplastics in marine sediments-North Sea and Skagerrak |
Narrative summary of dataset | This work was carried out for the Danish Environment Protection Agency (EPA) targeting microplastics (MP) in Danish marine sediments. It addresses the geographical distribution of MP in sediments from 23 stations, among which, 19 were analysed in 2022 (https://www.emodnet-ingestion.eu/submissions/submissions_details.php?menu=39&tpd=1185&step=001Denmark), and four were analysed in 2023. One of these four samples were collected from Skagerrak, and three were from the North Sea. It attempts to map the level and geographical distribution of MP in sediments from the North Sea and Skagerrak. The monitoring should furthermore create a baseline for future efforts to assess temporal changes of MP in Danish marine sediments. |
Summary of processing methodology | Samling: Top 2 cm sediments sampled with HAPS. Steps in sample reparation: sediments were pre-oxidised in 30% H2O2 -> wet sewed with Milli-Q water -> freeze-dried -> first density separation with sodiumpolytungstate times -> Enzymatic treatment with proteases/cellulase -> fentonoxidation, second density separation -> FTIR analysis. |
