Description
Marina Popova and co-authors test whether lake life can trap radioactive elements in a contaminated freshwater lake. Their 2026 study models Lake Dryazlo, a nutrient-poor lake in the Tver region, using its water and bottom sediments in the lab. They track four radionuclides: strontium, uranium, plutonium, and americium.
Phytoplankton soaked up notable amounts of all four during a single growing season. Sediments locked away the heavier actinides depending on their minerals and microbial activity. Adding a phosphate fertilizer boosted plankton growth and raised removal from the water several fold, while also fixing actinides in new mineral phases. The authors present living barriers as a practical option for cleaning radionuclide ponds. The approach could aid decommissioning of radioactive waste storage sites.
