Solid gallium is a blue-gray metal with an orthorhombic crystal structure. Gallium of great purity is silver in color. It is a solid at room temperature, but like mercury, cesium and rubidium, it becomes liquid when heated slowly. In solid form, it is soft enough to be cut with a knife. It is stable in water and air, but reacts or dissolves in acids and bases.

Health Effects of Gallium

Gallium is an element that occurs in the body in very small quantities. For example, a person weighing 70 kilograms has about 0.7 milligrams of gallium in their body. If this amount of gallium were to be concentrated in a cube, the cube would only have an edge length of 0.49 millimeters.
Gallium has no proven function in the body. It probably only occurs in this one, as it can be found in small traces in the environment, in the water and in remains of vegetables and fruits. It is known that some vitamins and commercially distributed water contain trace amounts of gallium of less than 1 mg / L.
Pure gallium is not a harmful substance in human skin contact. It is often touched because one is impressed that it melts in the hand, whereupon it stains the hand. The radioactive compound 67-Ga-Citrate can even be injected into the body and used for gallium sensing with no harmful effects. Gallium, while not harmful, should not be used in large doses.
Some gallium compounds can really be very dangerous. For example, acute exposure to gallium (III) chloride can cause the following symptoms: breathing difficulties, chest pain, laryngitis and its vapors can even cause very serious diseases such as pulmonary edema or partial paralysis.

Environmental effects of gallium

Gallium discussions relate to nuclear weapons and pollution. Gallium is used to hold some nuclear bombs together. If these fall apart, however, plutonium oxide powder is formed, which also contains gallium. This makes the plutonium unusable as a fuel because the gallium destroys some other elements. However, when the gallium is removed, the plutonium becomes useful again. The problem is that the process of removing the gallium entails a very large amount of radioactively contaminated water.
Gallium is an ideal element to use in the bomb pits, but pollution is harmful to the environment and human health.
Even efforts to decontaminate the contaminated water would fail because of the cost of the process. Scientists are working on a different method to clean up the plutonium, but this will take years of research.
