Bio-accumulation of lanthanum from lanthanum modified bentonite treatments in lake restoration
Abstract Lanthanum (La) modified bentonite (LMB) is one of the available mitigating agents used for the reduction of the phosphorus (P) recycling in eutrophic lakes. The potential toxicity of the La from LMB to aquatic organisms is a matter of concern. In this study the accumulation of La was invest...

Liver tissues showed the highest La increase, ranging from 6 fold (0.046–0.285 μg La g−1 DW) to ∼20 fold (0.080–1.886 μg La g−1, and 0.122–2.109 μg La g−1) two years following application and from 6 fold (0.046–0.262 μg La g−1) to 13 fold (0.013–0.167 μg La g−1) after five years in pelagic and littoral fish. The La content of the liver from Anguilla anguilla (eel) had increased 94 fold (0.034–3.176 μg La g−1) two years and 133 fold (0.034–4.538 μg La g−1) five years following LMB application.

Abstract Lanthanum (La) modified bentonite (LMB) is one of the available mitigating agents used for the reduction of the phosphorus (P) recycling in eutrophic lakes.
