Short summary
Phosphorus (P) release from sediments can delay recovery of eutrophicated waters. For the Stockholm inner archipelago (Baltic Sea), a P budget shows that legacy P release was small and restricted to the 20 years following the large P load reduction in 1975. Current P release is largely a seasonal P recycling in oxic conditions and the area is still a poor P sink. Short P turnover time in the area means that measures binding P in sediments will not be very effective in improving water quality.
Phosphorus (P) release from sediments can delay recovery of eutrophicated waters. For the...
