First observation of labile arsenic stratification in aluminum sulfate-amended sediments using high resolution Zr-oxide DGT.

Arsenic contamination in sediments has received increasing attention because it may be released to the water and threaten aquatic organisms. In this study, aluminum sulfate (ALS) was used to immobilize As in sediments through dosage-series and time-series experiments. Diffusive gradients in thin films (DGT) was used to obtain labile As at a vertically 2.0mm… CONTINUE READING
