Effects of Dredging and Lanthanum-Modified Clay on Water Quality Variables in an Enclosure Study in a Hypertrophic Pond

Abstract: An enclosure experiment was conducted between July and September 2009 to compare the effectiveness of a phosphate fixative, the lanthanum-modified bentonite clay Phoslock ® (LMB), dredging, and their combination in controlling eutrophication in a hypertrophic urban pond in Heesch, The Netherlands. In total, 25 water quality variables were monitored. Multivariate analysis revealed that the combination LMB-treated and dredged enclosures deviated most from the pond (reference) and the controls, and showed the str… Show more

“…In each pond, a fish stock assessment was performed that revealed a very high fish biomass over 1000 kg ha −1 (Table 1, [31][32][33]) with a majority (77-85%) being sedimentresuspending fish, such as carp and bream ) from external and internal sources for ponds Dongen, Eindhoven (based on [28]), and Heesch. The critical P loading thresholds for clear to turbid (red lines) and turbid to clear (green lines) were determined with the PCLake Metamodel [30].…”

“…To our knowledge, few eld-based studies have accessed the geochemical conditions leading to the suppression of P uxes from the sediments in the presence of DOC. 40 These studies point to a key interplay between La 3+ , DOC, and Fe, [40][41][42] which we set out to better understand using eld data and thermodynamic modelling.…”
