Beryllium produces a range of health effects from sensitization without evidence of disease to clinically apparent pulmonary disease. Chronic beryllium disease may be misdiagnosed as sarcoidosis. New immunologic tests promise early detection of beryllium disease and differentiation from other interstitial lung diseases.Web

Patients with chronic forms complain of insidious and progressive exertional dyspnoea, cough, chest pain, weight loss and asthenia. Symptoms may not manifest themselves until 20 years after exposure has ceased. Chest X-ray shows signs of diffuse infiltration, often with hilar adenopathy, reminiscent of the sarcoidosis picture.Web

AEC recommended 0.01 μg/m3 as a community air standard in 1949. Today, 0.01 μg/m3 averaged over a 30-day period remains an EPA ambient air quality criterion for beryllium.

Patients who have early beryllium disease but do not yet have symptoms may not require treatment. However, they need to be medically monitored. Some people who are detected at the early stages may go many years without needing treatment.

It is well established that beryllium causes sensitization (beryllium sensitization, BeS) and chronic beryllium disease (CBD). This chapter assesses the risk of those conditions posed by occupational exposure to beryllium. We first review the epidemiologic literature on BeS and CBD and then present the current clinical description of CBD with diagnostic, testing, …Web

Beryllium was used in fluorescent lights until 1949, when its health hazards were documented, including pneumonia-like acute beryllium disease, severe skin rashes, heart disease and lung cancer.

Introduction. An increased mortality from lung cancer was originally reported in workers from two beryllium plants in the United States (Lorain and Reading), who were first employed before 1955 and who were exposed to high levels of beryllium, including soluble beryllium compounds 1, 2.These and an additional five plants were included in a study of 9225 …Web

Key Points. Anyone working with or around beryllium metal, ceramics, alloys, or salts is at risk of developing beryllium sensitization or disease from inhaling small particles. Very low concentrations of beryllium in air can cause sensitization and disease. People living near a plant that uses beryllium and families of workers have developed CBD.Web

Beryllium is a silvery-white, lustrous, relatively soft metal of group 2 of the periodic table. The metal is unaffected by air or water, even at red heat. When copper and nickel are alloyed with beryllium they not only become much better at conducting electricity and heat, but they display remarkable elasticity.Web
