What health effects are associated with beryllium? According to NIOSH (the National Institute for Occupational Safety and Health, 2011), "workers exposed to particles, fumes, mists and solutions from beryllium-containing materials may develop beryllium sensitization or chronic beryllium disease, a potentially disabling or even fatal …

Beryllium exposure remains an ongoing occupational health concern for workers worldwide. Since the initial Occupational Safety and Health Administration (OSHA) ruling on a permissible exposure limit (PEL) for beryllium in 1971, our understanding of the risks of beryllium sensitization and chronic beryllium disease (CBD) has evolved substantially. …

Two distinct mechanisms of injury can result from beryllium exposure. In acute disease, high levels of beryllium exposure can result in inflammation of the upper and lower respiratory tract and airways, bronchiolitis, pulmonary edema, and chemical pneumonitis. (Kim 2004). Acute beryllium disease occurs less commonly than chronic beryllium ...

Berylliosis is a rare disease caused by prolonged exposure to the chemical element beryllium. Beryllium is a known carcinogen, or cancer causing agent, for both humans and animals, and it is commonly found in factory settings producing springs, gears, and cogs. Berylliosis occurs in 2 to 5% of workers exposed to beryllium and is a systemic ...

Chronic beryllium disease remains a common illness in industries that use beryllium and beryllium alloy. It differs from most pneumoconioses in that it is a cell-mediated hypersensitivity disease. Beryllium is presented to CD4 + T cells by antigen-presenting cells, principally in HLA-DP molecules. T cells in the blood, lungs, or other organs, in …

Exposure to beryllium and certain beryllium compounds can result in beryllium sensitization, which may develop into a disease of the lungs called chronic beryllium disease (CBD). Beryllium sensitization is an "allergic" condition to beryllium that can develop primarily after a person breathes air containing beryllium mists, dusts, and fumes.

beryllium disease develop lesions (masses) in the lungs that can lead to scarring. They may experience chest pain, cough, and/or shortness of breath. Skin contact with beryllium may cause an allergic response or lead to beryllium sensitization. Studies in animals have shown that eating or drinking beryllium may cause stomach damage. If you work ...

2.1 Occupational Disease. Chronic beryllium disease (CBD), which is a cell-mediated granulomatous hypersensitivity, is the most common chronic occupational reaction to beryllium and typically involves the lungs and skin, with isolated reports of granulomas in the liver, kidney, muscle, and lymph nodes [9, 12].Acute beryllium disease (ABD) with …
