Results of metal and As fractionation in sediments with and without DWTR after incubation.

The individual fraction content is the mean content in sediments with or without DWTR after incubation under different conditions. The error bars indicate the variations in each fraction proportion among the 8 samples. For each metal and As, the left column is the element in sediments with DWTR, whereas the right column is the element in sediments without DWTR. *And **represent significant differences at p < 0.05 and 0.01, respectively, for metal and As fractions between sediments with and without DWTR.
