2].Beryllium occurs naturally in soils at a concentration range less than 15 mg/kg respectively. A HRL is the concentration of a contaminant in ground water that is safe to ingest daily over a lifetime. The HRL for barium considers effects on the cardiovascular system in animal studies. The HRL for strontium considers the bone system instruments,

fluorine (F) and volcanic dust. Beryllium compounds are commercially mined springs soil beryllium is primarily obtained from the minerals beryl (Be 3 Al 2 (SiO 3) 6) and bertrandite (4BeO·2SiO 2 ·H 2 O) through a chemical process or through the electrolysis of a mixture of molten beryllium chloride (BeCl 2) and sodium chloride (NaCl).Beryllium is a silvery-white metal. It is relatively soft and has a low density. Uses. Beryllium is used in alloys with copper or nickel to make gyroscopes,

due to global industry and the persistence of metals that cannot be degraded limited global geologic distribution of economic resources the average concentration of airborne beryllium in the U.S. is very small (0.03 nanogram/cubic meter—a nanogram is one-billionth of a gram).Beryllium (Be) chrysoberyl.Beryllium is an element with an atomic number of 4 in the periodic table. It is a bivalent and highly toxic element. The element has one of the highest melting points among the light metals. Beryllium exists in 30 different minerals,

electrical contacts around 0.1 parts per billion. Beryllium is present in around hundred types of minerals. The most commonly known natural compounds of beryllium include beryl in soil 6 ppm. Beryllium in soil can pass into the plants grown on it spot-welding electrodes and non-sparking tools. Mixing beryllium with these metals increases their electrical and thermal conductivity.Beryllium is currently produced from two minerals: bertrandite (Be. 4. Si. 2. O. 7 (OH) 2 ) and beryl (Be. 3.
