Eucalyptus - a tree that grows yellow

Tree grows gold

Eucalyptus (Eucalyptus) is a genus of flowering plants in the family Dao kim nuong - native species of Australian origin. In Vietnam eucalyptus is quite familiar to people because it is often grown quite a lot to extract essential oils for eucalyptus oil and wood.

In 2013, the Australian scientific community published a shocking discovery about this plant, which is on leaves containing gold. Because the root pile can be plugged up to 40m to find water when growing in their arid areas. If the roots reach the groundwater near the gold mines, it will attract the gold crystals.

Because gold is not a toxic metal for plant life, eucalyptus has a mechanism to put gold on the ends of plants, such as leaves, to minimize toxic biochemical reactions.

Experts have tested growing eucalyptus in soil containing gold crystals and comparing eucalyptus leaves growing near a Western Australia gold mine, with plants growing 800m away.

As a result, inside the leaves contain gold crystals about 8 micrometres in size.

Why don't we think of gold from here

Because even when eucalyptus is planted on a gold mine, the ratio of gold in the leaves is only about . 46 parts per billion, or about 0.000005% by weight of the leaves. This means that even if you have 500 eucalyptus trees, you will be able to create a small ring.

The number of gold in 500 eucalyptus trees just barely cast 1 ring

Don't be disappointed, though, because even though they don't make much gold, they mean a lot to the environment around us .

Because the process of finding gold mines takes a lot of time, money and is very harmful to the environment. Thanks to eucalyptus trees, we have a less expensive, highly effective method and minimize the negative impacts on the environment.
