Abstract

The effect of soil amendments on the bioavailability of heavy metals has been progressively examined both in the field and under laboratory conditions. To evaluate the effect of three soil amendments, i.e., chicken manure (CM), peat (PE) and vermiculite (VE) on Cr bioavailability, we planted Lolium perenne (L. perenne) and Pharbitis purpurea (P. purpurea) in soils contaminated with 1000 mg•kg-1 Cr (III) in the laboratory. The results showed that all three amendments decreased the bioavailability of Cr (III). Cr (III) accumulation in L. perenne was most significantly reduced by CM, leading to a Cr (III) concentration that was only 54.1% of that of the control. CM alleviated Cr (III) stress on the plants, most obviously. Therefore, CM have the potential to serve as efficient soil amendments for Cr-contaminated soil.
