Boron is a non metallic element and the only non-metal of the group
13 of the periodic table the elements. Boron is electron-deficient,
possessing a vacant p-orbital. It has several forms, the most common of
which is amorphous Boron, a dark powder, unreactive to Oxygen, water,
acids and alkalis. It reacts with metals to form borides.
The most economically important compound of Boron is Sodium
tetraborate decahydrate Na2B4O7 · 10H2O,
or borax, used for insulating fiberglass
and Sodium perborate bleach. Boric acid is an important compound used in
Boron in the environment
Boron is not present in nature in elemental form. It is found
combined in borax, boric acid, kernite, ulexite, colemanite and
borates. Vulcanic spring waters sometime contains boric acids.
Humans can be exposed to Boron through fruit and vegetables, water, air and consumer products. we have a regular daily intake of about 2 mg and about 18 mg in out body in total.
When humans consume large amounts of Boron-containing food, the Boron concentrations in their bodies may rise to levels that can cause health problems. Boron can infect the stomach, liver, kidneys and brains and can eventually lead to death. When exposure to small amounts of Boron takes place irritation of the nose, throat or eyes may occur. It takes 5 g of borc acid to make a person ill and 20 grams or more to put its life in danger.
Eating fish or meat will not increase the Boron concentrations in
our bodies, as Boron does not accumulate within the tissues of
Boron is an element that occurs in the
envIronment mainly through natural processes.
Boron exposure through air and drinking water is not very likely
to occur, but the risk of exposure to borate dust in the workplace
does exist. Boron exposure may also occur from consumer products
such as cosmetics and laundry products.
