Influence of Sulfur on the Arsenic Phytoremediation Using Vallisneria natans (Lour.) Hara

Influence of Sulfur on the Arsenic Phytoremediation Using Vallisneria natans (Lour.) Hara Influences of sulfur (S) on the accumulation and detoxification of arsenic (As) in Vallisneria natans (Lour.) Hara, an arsenic hyperaccumulating submerged aquatic plant, were investigated. At low sulfur levels (<20 mg/L), the thiols and As concentrations in the plant increased significantly with increasing sulfate nutrient supply. If sulfur levels were above 20 mg/L, the thiols and As concentrations in the plant did not increase further. There was a significant positive correlation between thiols and As in the plant. As(III) is the main form (>75%) present in the plant after exposure to As(V). Sulfur plays an important role in the arsenic translocation and detoxification, possibly through stimulating the synthesis of thiols and complexation of arsenite-phytochelatins. This suggests that addition of sulfur to the arsenic-contaminated water may provide a way to promote arsenic bioaccumulation in plants for phytoremediation of arsenic pollution. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Bulletin of Environmental Contamination and Toxicology Springer Journals
