Metal mobilization and redistribution

A laboratory study on the Eastern Gotland Basin found that reoxygenating anoxic sediments releases several metals into the water column, particularly redox-sensitive elements like manganese, uranium, and molybdenum, which appeared in higher concentrations than previously recorded in the region.

• Reoxygenation of sediments from the North and South Eastern Gotland Basins over a 96-hour period led to the release of several metals into the water column, including Arsenic, Ba, Co, Mn, Rb, U, K, Sr, and Mo. The highest concentrations of released metals were redox-sensitive elements, specifically manganese (Mn), uranium (U), and molybdenum (Mo).
• The concentrations of manganese (Mn), molybdenum (Mo), uranium (U), and arsenic (As) released during the experiment exceeded previously measured levels in the Eastern Gotland Basin.
• Electroconductivity (EC) measurements indicate that the release of metals occurs during the initial 12 hours of the reoxygenation process.
