Pollution by marine debris including microplastics has become a serious environmental problem, and scientists all over the world are exploring its status by carrying out a survey on microplastics accumulated in marine species. The effects of marine debris have spread through the food chain to marine species such as polar cod living in the Arctic Ocean and deepwater shrimp (order Amphipoda) living at depth, which should have been hard for the impact of pollution to reach. Moreover, microplastics have even been found in the polar ice.

A group of scientists from Newcastle University in the UK and Wageningen Marine Research in the Netherlands collected the stomach contents of various marine creatures to separate microplastics of approximately 100 μm in size to conduct a survey on the impact of marine debris. This article introduces an example of analysis using an infrared microscope on microplastics collected from polar cod and deepwater shrimp.
