Abstract:

The aim of this research project was to investigate the efficiency of fulvic acid or straw water as an amendment to enhance the uptake of arsenic from groundwater by Vetiveria. Fulvic acids and straw water were applied to arsenic-contaminated groundwater at different concentrations (0.1% and 0.01%). It was found that when the higher concentration of straw water was added to the groundwater solution, the efficiency of arsenic accumulation by roots was increased 47.8%. Straw water not only enhances the growth of Vetiveria, but also improved arsenic accumulation in both shoots and roots. In contrast, the addition of fulvic acids (at high or low concentrations) resulted in the reduction of Vetiveria growth. Specifically, a high concentration of fulvic acid reduced arsenic accumulation in roots whilst a low concentration of fulvic acid decreased arsenic accumulation in shoots.
