Predicting the long-term effects of iron addition on phosphorus dynamics in streams using modelling and high-resolution in-situ techniques. KU Leuven
Excessive phosphorus (P) concentrations are the primary cause of eutrophication of freshwaters. To mitigate the negative ecological effects of eutrophication, P may be immobilised in the sediment. The chemical immobilisation of P by adding ferric iron (Fe(III))-based materials is the most widely adopted one. However, biogeochemical processes in sediment gradually lower the P trapping efficiency, e.g. Fe(III) reduction leading to Fe(II) ...
