Mikroplastik i havmiljøet - Metode til kvantificering af mikroplastik i havvand, blåmusling og fisk
AI summary Read the abstract
This Danish pilot study adapted methods for identifying microplastics in marine biota and used them to assess microplastic occurrence in seawater, blue mussels, eel pouts, sculpin, and Atlantic cod at two coastal sites near Copenhagen. The work contributes baseline data on microplastic contamination in Danish coastal ecosystems.
This study examines the methods used for identifying microplastic in marine biota. The methods were modified and used in a pilot-study describing the occurrence of microplastic in seawater and biota on two coastal locations near Copenhagen. Coastal seawater, blue mussles (Mytilus edulis), eel pouts (Zoarces viviparous), sculpin sp.(Cottidae sp.) and Atlantic cod (Gadus morhua), were examined for microplastic in the organism. For improving detection of microplastic, organic matter was removed using an alkaline sodium hypochlorite solution (NaClO). After removal of organic matter, samples were filtered and examined under microscope at 40x. For blue mussel the whole organism was analyzed, and stomach and gut were analyzed on fish. The organisms were pooled by species. It is shown that microplastic is present in both coastal seawater and biota. Chemical digestion using base seems to be the best method to remove organic material and make identification of microplasticpossible. This study discusses the need for improving methods to identify and characterize microplastic. Præsenteret som foredrag på det 18. danske havforskermøde.

This Swedish study examined the occurrence of microplastics in blue mussels (Mytilus edulis) collected from the West Swedish coast, contributing to data on microplastic contamination in edible shellfish from the North Sea region. The findings are relevant to assessing human dietary exposure to microplastics through seafood consumption.
Exploration of occurrence and sources of microplastics (>10 μm) in Danish marine waters
AI summary Read the abstract
Microplastics larger than 10 micrometers were quantified in Danish marine waters of the Kattegat and southern Skagerrak, an area receiving Baltic Sea inflow and urban runoff from Copenhagen and Malmö. The study establishes baseline concentrations and identifies urban and riverine inputs as key sources to these regional seas.
Screening for microplastics in sediment, water, marine invertebrates and fish: Method development and microplastic accumulation
AI summary Read the abstract
Researchers developed improved methods for extracting microplastics from biological samples and sediments, using enzymatic digestion that achieved 97% particle recovery without damaging the plastics. When applied to field samples from the North Sea and Swedish coast, they found microplastics in 8 of 9 invertebrate species tested and in 68% of brown trout. Mussel tissue contained roughly a thousand times more microplastic particles per kilogram than surrounding sediment or water.
Testing a monitoring strategy for floating microlitter with manta-trawl sampling in Danish coastal waters
AI summary Read the abstract
This Danish monitoring project developed and tested a coastal sampling strategy for floating microplastics using manta-trawls at beach litter monitoring sites. The study found relatively low microplastic concentrations in Danish marine surface waters, providing baseline data and an evaluated monitoring protocol for ongoing national microplastic surveillance.
