In recent years, the eutrophication of Caohai Lake has intensified, presenting a significant trend to an algae-type “muddy-water state” in some areas.
TOC and TN both had highly significant correlations with OSF-Si and Valid-Si, which demonstrated that Valid-Si had excellent coupling relationships with C and N in the sediments.
