文摘
- •
Diffusive gradients in thin films (DGT) probes were used to measure As profiles.
- •
As profiles were measured under larval bioturbation and varying flow rates.
- •
Active larval bioturbation decreases the concentration of labile As in sediments.
- •
Higher hydrodynamic intensities decrease the concentration of As in sediments.
- •
Labile As and Fe concentrations are correlated, suggesting As-Fe coupled cycling.
