Accumulation of As, Ag, Cd, Cu, Pb, and Zn by Native Plants Growing in Soils Contaminated by Mining Environmental Liabilities in the Peruvian Andes
Researchers tested native Andean plants growing in mining-contaminated soils for their ability to absorb heavy metals like lead, arsenic, and copper, finding that different plants accumulate different metals in their roots, stems, and leaves. This phytoremediation research is relevant to understanding how contaminated soils near plastic production and waste sites might be cleaned up.
Phytoaccumulation of Heavy Metals in South Kazakhstan Soils (Almaty and Turkestan Regions): An Evaluation of Plant-Based Remediation Potential
Researchers tested whether sowing peas could be used to clean up heavy metal contamination in the soils of South Kazakhstan, where mining and industrial activities have left elevated levels of copper, nickel, and cobalt. They found that the pea plants were able to accumulate these metals in their roots and biomass, showing promise for phytoremediation. The study suggests that growing metal-accumulating plants in polluted soils could be a practical strategy for reducing heavy metal contamination in agricultural regions.
