Hyperaccumulators plants

WebHyperaccumulators are known for their capability of absorbing metals in anomalous amounts. The initial phase of the project is focused on the identification and propagation of these plants for copper and arsenic uptake. These potential hyperaccumulators will also be used to stabilize the mined out areas and facilitate plant succession. WebThis study was focused on determining Arsenic (As), Lead (Pb), Cadmium (Cd) and Zinc (Zn) in 33 indigenous plants and 12 soil in-situ plant samples in Thai Nguyen Province, Vietnam.
