Effect of amendment on phytoextraction of arsenic by Vetiveria Zizanioides from soil
Abstract: The present study was undertaken to evaluate the growth response of Vetiveria zizanioides amended with organic amendments to arsenic (As) in contaminated soils and its ability to sequester As. The test results indicate that the plants exhibited high tolerance to As in the soils and their normal growth continued even though As concentration reached 500 mg/kg. However, when As ...

Influence of phosphate and citric acid on the phytoextraction of As from contaminated soils
The influence of phytoextraction in arsenic (As) contaminated soil on the phosphate and citric acid addition were investigated using Pteris vittata L. (Chinese brake fern). The As uptake in the fronds increased 85% in As–spiked soil when phosphate was added. The addition of citric acid for 2 weeks to the phosphate added soils resulted in the highest As uptake by 75% compared to only ...

The fate of arsenic in contaminated paddy soil with gypsum and ferrihydrite amendments
Ferrihydrite and gypsum (CaSO4·2H2O) are two chemicals which were suggested to reduce the bioavailability of arsenic (As) in agricultural field. The efficiency of those chemicals added in the paddy field was investigated by pot culture in this study. The results showed As uptake by rice under ferrihydrite treatment was significantly lower than that in the control (36% in shoot), however, plants ...

Characterisation of antimony, arsenic, cadmium, copper and tin occurrences at an abandoned sulphide-mining area
Contamination levels in top-soil, vascular plant and surface water samples from the Sao Domingos mining area, Portugal, were determined by Instrumental Neutron Activation Analysis (INAA) and Compton-Suppression Neutron Activation Analysis (CSNAA). The total levels of As, Cd, Cu, Sb and Sn are reported with a discussion of plant uptake and transfer coefficients. Comparative analysis of the same ...
