Rare rain forest tree bleeds toxic metal: BRAND-NEW CALEDONIA: A rare rain forest tree that grows on the island of New Caledonia in the South Pacific bleeds a very poisonous metal when it is reduced by the bark.
According to the details, when the bark of Pycnandra acuminata is reduced, it hemorrhages, oozing out a bright blue latex that contains up to 25 percent nickel, a steel highly toxic to most plants.
If these metal-containing plants are dried as well as shed to ash, they can yield very rich, top-quality steel ore, creating far much less contamination as well as utilizing much less power than required in conventional mining.
Dr Antony van der Ent, a scientist at the College of Queensland informed BBC, “Pycnandra acuminata is a big (up to 20m tall) rare jungle tree, restricted to remaining spots of jungle in New Caledonia.”
” As a test-subject it is challenging because it expands extremely gradually, and also it takes years to get it to generate blossoms as well as seeds. It is endangered by logging as a result of mining activities as well as bush fires.”
“The development of hyperaccumulation has actually advanced sometimes over in extremely various families, and most likely has taken numerous years. These plants are located on normally metal-enriched dirts,” the researcher added.
It could be a method to safeguard versus insect assaults or probably to stand up to fungal infections.
