Details of plastic ingestion and fibre contamination in North Sea fishes.

This study combines published datasets with unpublished data on plastic ingestion in several North Sea fish species. The combined dataset of 4389 individuals from 15 species allows the analysis of spatial distribution and temporal variability of plastic uptake in fish. Airborne fibre contamination was observed to be the main contributor to fibres encountered in the samples.

Plastic ingestion by juvenile polar cod () in the Arctic Ocean.

One of the recently recognised stressors in Arctic ecosystems concerns plastic litter. In this study, juvenile polar cod () were investigated for the presence of plastics in their stomachs. Polar cod is considered a key species in the Arctic ecosystem.

The use of potassium hydroxide (KOH) solution as a suitable approach to isolate plastics ingested by marine organisms.

In studies of plastic ingestion by marine wildlife, visual separation of plastic particles from gastrointestinal tracts or their dietary content can be challenging. Earlier studies have used solutions to dissolve organic materials leaving synthetic particles unaffected. However, insufficient tests have been conducted to ensure that different categories of consumer products partly degraded in the environment and/or in gastrointestinal tracts were not affected.
