One potential hyperaccumulator plant in Papua New Guinea that could be used for mine rehabilitation to remediate polluted water and land is the Alyxia buxifolia, also known as the Sea Boxwood.
This plant has been found to have a high tolerance for heavy metals and can absorb and accumulate these pollutants in its tissues, making it an effective natural remediation tool for contaminated environments. Alyxia buxifolia has been used successfully in other countries for phytoremediation purposes and could potentially be a viable option for mine rehabilitation in Papua New Guinea.
What are other plants used in highland region mining area
1. Pteris vittata (Chinese brake fern): This fern is known for its ability to accumulate and tolerate high levels of arsenic, making it useful for phytoremediation in contaminated mining areas.
2. Vetiveria zizanioides (vetiver grass): This grass is commonly used for soil stabilization and erosion control in mining sites, as it has deep roots that can penetrate and break up compacted soil while also helping to absorb pollutants.
3. Phragmites australis (common reed): This tall grass species is often used for phytoremediation in mining areas, as it can effectively absorb and accumulate heavy metals and other pollutants from water and soil.
4. Lycopersicon esculentum (tomato plants): Tomato plants have been used for phytoremediation in mining areas due to their ability to absorb and accumulate heavy metals such as lead and cadmium.
5. Brassica juncea (Indian mustard): This plant species is known for its ability to hyperaccumulate heavy metals such as lead, cadmium, and nickel, making it a valuable tool for phytoremediation in mining areas.
