Most people are exposed to low levels of beryllium in air, food, and water. People can be exposed to higher levels of beryllium if they work mining, processing, or otherwise working with beryllium. People living near these industries or near hazardous waste sites may also be exposed to high levels of beryllium. Health Effects
Berylliosis is a pneumoconiosis that results from inhalation of dust of the metal beryllium. The disease initially was described in individuals who manufactured fluorescent light bulbs, but more recent cases involve workers in the aerospace, nuclear weapons, and electronics industries and other industries where beryllium is used.

5. PRODUCTION, IMPORT/EXPORT, USE, AND DISPOSAL . Copperberyllium alloy is commercially the most important beryllium alloy. Copperberyllium master alloy is manufactured by an arcfurnace method in which beryllium oxide is reduced by carbon in the presence of molten copper at 1,800–2,000 EC. The resulting master alloy usually contains ...
Even the Defense Department's beryllium stockpiling program could not prevent a fouryear slump that began in 1988. Sales declined by nearly 23 percent, from million in 1988 to million in 1991, and the company went from a net surplus of million to a 44 million deficit.

Beryllium is primarily produced using bertrandite and beryl ores. However, 90% of the current production is derived from bertrandite ore. The rising demand for the metal is anticipated to compel ore mining companies to invest in new sites. However, depleting raw material resources are estimated to be a key concern for the industry.
