Berylliosis disease Britannica

Berylliosis, systemic industrial disease caused by poisoning with beryllium, usually involving the lungs but occasionally affecting only the skin. There are two forms: an acute illness occurring most frequently in workers extracting beryllium metal from ore or manufacturing beryllium alloys, and a

Beryllium Disease ILO Encyclopaedia

2021-7-9 Beryllium disease is a systemic disorder involving multiple organs, with pulmonary manifestations being most prominent and common. It occurs on exposure to beryllium in its alloy form or in one of its various chemical compounds. Route of exposure is by inhalation and the disease can be either acute or chronic.

It is opportune in a symposium on sarcoidosis to discuss beryllium disease because it mimics so closely the naturally occurring Boecks sarcoid and yet carries a far graver prognosis. Beryllium was first reported to possess toxic properties by Weber and Englehardt (I933) in Germany. They described bronchitis and acute respiratory disease in workers extracting beryllium from ore.

Although these results are derived from a small sample, this study suggests that the form of beryllium may affect the likelihood of developing CBD. Specifically, exposure to beryl and bertrandite ore dusts or to beryllium salts, in the absence of exposure to beryllium oxide particulates appears to pose a lower risk for developing CBD.

2018-4-14 An estimated 300,000 workers are exposed to beryllium during ore extraction, processing, and manufacturing. Potential toxicities include acute and chronic beryllium disease (CBD) and lung cancer.

Beryllium Disease ILO Encyclopaedia

2021-7-9 Beryllium in all its forms, except for beryl ore, has been associated with disease. The route of entry is by inhalation and in the acute disease there is a direct toxic effect on both the nasopharyngeal mucosa and that of the entire tracheobronchial tree as well, causing oedema and inflammation.

Chronic Beryllium Disease

Chronic Beryllium Disease (CBD) is an occupation-related disease characterized by lung exposure to beryllium. it is also called berylliosis.. Beryllium is a naturally occurring lightweight material that can easily be inhaled in the forms of dust or fumes.

Chronic Beryllium Disease Conditions UCSF Health

Chronic beryllium disease, or CBD, causes scarring of the lung tissue. It occurs when a person inhales dust or fumes of beryllium — a naturally occurring lightweight material — and has become sensitized to this material. Beryllium is used in various industries, such as electronics, aerospace, dental, atomic energy and defense.

Chronic beryllium disease (CBD, chronic pulmonary granulomatosis, berylliosis) is the most common health problem caused by exposure to beryllium. This disease was described for the first time by Hardy and Tabershaw (1946) in fluorescent-lamp workers exposed to beryllium fluoride in Massachusetts and originally named as “Salem sarcoid.”

The Risk Assessment Information System

Chronic beryllium disease is a systemic disease that primarily affects the lungs and is characterized by the development of non-caseating granulomas. The disease most likely results from a hypersensitivity response to beryllium as evidenced by positive patch tests (Nishimura, 1966) and positive lymphocyte transformation tests (Williams and
