The shipwrecks at Måseskär

In an area west of the island of Måseskär in Skagerrak, 28 ships were scuttled after World War II. Over the years, low levels of chemical warfare agents have been detected in sediment and in fish, indicating that the ships contain dumped chemical warfare agents.

In 1992, low concentrations of sulphur mustard were detected in the sediments in the area, and in 2016 and 2017, low concentrations of the chemical warfare agent (CWA) Clark I was found in Norwegian lobster, flatfish and shrimps. Further studies are performed to investigate which wrecks contain chemical warfare agents, the extent of the contamination and their potential impact on the environment.
