Short summary
The pyritic material studied here had the highest Cr(VI) retention, whereas the lowest corresponded to granitic material. The highest Cr retention was achieved at very acid pH. The amendment with 12 t ha-1 mussel shell did not cause marked changes in Cr(VI) retention. Regarding Cr(VI) fractionation, the soluble fraction was dominant in mussel shell and in the unamended and amended granitic material, whereas more stable fractions dominated in the pyritic material and in the forest soil.
