Beryllium

Pollution of this metal is also associated with the development of industry, and, moreover, the most modern nuclear power. For enterprises with large powerful sources of atomic energy (beryllium is a source of neutrons in nuclear reactors), in factories and quarries, where the concentration of this element reaches 0,01 mg per 1 m3 of air, can already be observed signs of poisoning. There are three degrees of poisoning: I - the so-called fever foundry, passing through the 24 or 48 hours; II - toxic pneumonia, appearing even after several years; III - chronic poisoning, called berylliosis, or industrial sarcoidosis in lungs. Statistics show that 100 such poisoning is 10 deaths. The first case was noted already in 1930, but then in 1 m3 of air was only 25 mg of beryllium.
Beryllium belongs to those non-radioactive elements, the use of which has increased over the last 20 years by about 500 %, while, for example, boron, 78 % of chromium - 50 %, copper - by 30 %, manganese - by 45 %, Nickel - by 70 %, zinc - by 44 %.
The needs of industry in this element has increased dramatically, and it bothers doctors and nutritionists, the more that beryllium is also used in rocket engines, not only in missiles for atmospheric research, but also in military technology. It is known that the missiles for atmospheric research uses several Tony beryllium a year, and how many in the military equipment? In the USSR from 1963 are looking for material that could replace the item.
Beryllium is a rare element on our planet - has many valuable properties. It is very light (4.5 times lighter than iron) and bombarded with alpha particles becomes a rich source of neutrons. Enrico Fermi used drugs radium and beryllium in experiments that gave the world the first reactor.
For many years beryllium together with zinc fill color of a street lamp with fluorescein light of those who subsequently proved harmful. Beryllium does not rust. Another huge advantage: beryllium powder, constantly used in fuel mixtures for missiles, when burned, release large amounts of energy.
But one drawback it outweighs all its advantages: it is toxic, moreover, even in small quantities. More it affects women, and sometimes men's killing.
Experiments on chickens showed that beryllium poisoning them fatally. Even if there were chickens from poisoned eggs, they were freaks with different strains. And chickens poisoned beryllium, carrying eggs larger than normal, as if he were trying in this way to get rid of the poison.
