Beryllium and its compounds are listed as toxic chemicals under the Emergency Planning and Community Right-to-Know Act of 1986; estimates of releases of beryllium and its compounds into air, water or land must be reported annually and entered into the national Toxic Release Inventory (TRI).
Heavy metals are naturally occurring elements that have a high atomic weight and a density at least 5 times greater than that of water. Their multiple industrial, domestic, agricultural, medical and technological applications have led to their wide distribution in the environment; raising concerns over their potential effects on human health and the environment.

Beryllium is a poisonous earth metal that inhibits the alkaline phosphatase, acid phosphatase, phosphoglycerate mutase, hexokinase, and lactate dehydrogenase enzyme systems in the body. Exposure through food and water is not clinically significant, owing to the low level of exposure and the limited absorption of beryllium by the stomach and ...
Treat symptomatically. Contact poison treatment specialist immediately if large quantities have been ingested or inhaled. Airborne particles of beryllium alloys can, if inhaled to excess, cause irreversible lung damage in people who are sensitive to beryllium. Prevention of this adverse health effect (called berylliosis or, more precisely, chronic
Beryllium oxide was less toxic than beryllium sulfate, due to its relative insolubility in the lung. Based on limited comparisons among compounds and species, rats and monkeys appear to be more sensitive than hamsters and guinea pigs. Exposure to 0.43 mg beryllium/m. 3 .
· Beryllium is also used in the production of nuclear weapons. With that, you may not be surprised to learn that beryllium is one of the most toxic elements in existence. Beryllium is a Class A EPA carcinogen and exposure can cause Chronic Beryllium Disease, an often fatal lung disease. Sources of Beryllium Exposure. Every day, we''re all exposed ...
· The Occupational Safety and Health Administration says coal and copper slag contain traces of highly toxic beryllium, arsenic and other contaminants. ... a Canada-based company with a copper …
· Also, airborne beryllium particulates are toxic requiring shops to follow stringent safety precautions for safe machining. Beryllium metal (>98 percent Be) is extremely stiff and lightweight and has a modulus of elasticity almost 50 percent greater than …
Jones Day represented Materion Brush Inc., a fully-integrated manufacturer of beryllium-containing products, in litigation in which plaintiffs alleged that they were exposed to beryllium alloy particulates in the manufacture of golf clubs. Plaintiffs worked for Karsten Manufacturing Corporation in 1979-97. Karsten made golf clubs, sold under the Ping brand name, with heads of cast copper ...
Because small amounts of beryllium are toxic and are added to many copper, aluminum, nickel, and magnesium alloys, workers are often unaware of their exposure and its risks. In addition to workers in these industries, a few people living near beryllium refineries also have developed beryllium disease.
Beryllium copper is a valued metal alloy known for its high strength and hardness, combined with high electrical and thermal conductivity. It is non-ferrous, non-magnetic, and non-sparking.
