Here is some great news, brought to us by Natural News on a rare plant found to be able to remediate heavy metals.
The new species, dubbed Rinorea niccolifera, was identified in the western region of Luzon Island in the Philippines. The soils in this area are well-known for being high in heavy metals, an environmental condition that is hostile to most species of plant. Yet, the newly discovered plant is able not only to grow in such conditions but also to thrive. The plant actively pulls nickel out of the soil, accumulating it in its tissues up to a concentration of 18,000 parts per million — 100 to 1,000 times higher than the maximum concentrations tolerated by most plants.
Nickel hyperaccumulation such as that observed in R. niccolifera is so rare that only 450 plant species have been identified that are capable of it, out of an estimated 300,000 extant species of vascular plant worldwide. Even among plants found in nickel-rich soils, only 0.5 percent to 1 percent are capable of hyperaccumulation.
“[Hyperaccumulator] plants have great potentials for the development of green technologies, for example, ‘phytoremediation’ and ‘phytomining,'” researcher Augustine Doronila said.
My comment; For countries like China where 1/5th of the country is poisoned with heavy metals these plants would be the solution to the pollution. This is about nickel, we need to get more for cadium, for lead, for mercury etc but the green folk and the microbes and fungi will all need to help clean up the mess we have made.
