Labile P, Fe, and sulfide with the high spatial resolution in sediment porewater of five sites (A–E) of Dianchi Lake (China) were measured at same locations using AgI/Chelex-100, Chelex-100, and ferrihydrite DGT (diffusive gradients in thin films) probes. DGT derived P/Fe/S concentrations in sediment porewater on millimeter or sub-millimeter scale in order to reveal the element remobilization process and the mechanism of “internal P-loading-of sediments in Dianchi Lake. Decomposition of alga biomass in the uppermost sediment layer and the reductive dissolution of Fe-bound P in the anoxic sediment were the two main processes causing P release. A dynamic numerical model-DIFS (DGT-induced flux in sediments) was used to assess sediment-P reactivity (capacity of solid pool and rate of transfer) and P release risk by kinetic parameter-em class="EmphasisTypeItalic ">T _C (1089?0,450 s), distribution coefficient-em class="EmphasisTypeItalic ">K _d (167.09?02.0 cm3 g?), resupply parameter-em class="EmphasisTypeItalic ">R (from 0.242 to 0.518), and changes of dissolved/sorbed concentration, R and M at the microzone of DGT/porewater/sediment.
