Abstract
Two series of laboratory experiments mimicking dredging of the uppermost phosphorus (P) rich sediment layers of the shallow eutrophic L. Müggelsee were carried out to study the extent of P release from deeper sediment layers, and changes in P mobility by means of fractional P composition of the in 10 cm steps ‘dredged’ sediment cores. In the first run over 38 days, the aerated controls reached 55%, and the ‘dredged’ cores from 18.1% (−10 cm) down-core to 0.4% (−50 cm) of the non-aerated control (50.82 mg P m−2 d−1 = 100%). In the second run over one year, the fractional P composition in the revealed sediment layers changed slightly. The water-soluble P (H2O-P) increased for the respective ‘dredged’ horizon by between 1.5 and 5.6% TP. The redox-sensitive P (BD-P) increased in each horizon from the intact core to the situation following ‘dredging’, as well as with depth in each horizon from 4.9% TP (−10 cm) to 11.4% TP (−40 cm). The organic bound P portion (NaOH-NRP) decreased least (1.7% TP) in the uppermost layer and most (15.6% TP) in the deepest horizon exposed to water after ‘dredging’. Based on the changes in P pools following dredging at the future sediment–water interface, it is predictable that dredging without reduction of the external loading may give only temporary improvement followed by a slow return to the present situation.
