1. Beryllium By: Chelsea, Chris, Julie

2. Chronic Beryllium Disease(CBD) • Lung Disease • Takes 15 to 30 years to show up • Locate in the chemical compounds of coal, oil, volcanic dust, and two types of mineral rocks (bertrandite and beryl) • Has a distinct smell Effects -persistent coughing -shortness of breath -chest pain, -Fever -night sweats -blood in spit -rapid heart beat -loss of appetite -weight loss

3. Case Study • A study of 689 patients(421 men) with beryllium disease consisted of 28 deaths from lung cancer • Adjustments of smoking did not make a difference • A point later was made that one was more pronounced with acute disease than among those with chronic disease.

4. Construction workers at Department of Energy (DOE) • less than 1% have been found to have CBD. • Machinists in beryllium operations • 10 to 14% of the workers have gotten chronic beryllium disease. • No cure for chronic beryllium disease. • Treatment is available that can help slow the progression of the disease

5. Use/work in areas which are as ventilated as possible Work with non-beryllium metals, alloys, ceramics and salts. Do not eat, drink or smoke in areas where beryllium is in use. Before entering work areas where beryllium is used, change into work clothes, including shirt, pants and shoes. At the end of the work shift take a shower and thoroughly clean your hands and hair before changing into street clothing. Use respirators for tasks that result in higher exposures.

6. HistoryCases of chronic berylliosis were first described in 1946 among workers in plants manufacturing fluorescent lamps in Massachusetts. Chronic berylliosis resembles sarcoidosis in many respects, and the differential diagnosis is often difficult. It occasionally killed early workers in nuclear weapons design, such as Herbert Anderson.[49]A new case of chronic beryllium disease is described, occurring in a 33-year-old man who had worked with beryllium alloys in 1961. Weight loss and muscle pains were the main clinical features while radiological changes were minor. Serial lung function studies showed improvement after corticosteroids, but impairment of gas transfer remained.

7. Fun facts • Beryllium is the lightest alkaline earth metal • The element beryllium is rare in the universe because beryllium was created by the Big Bang and is not typically formed by the nucleosynthesis reactions of stars. • The name originates from the Greek word beryllos meaning beryl. • Beryllium was discovered in France by Nicolas-Louis Vauquelin in beryl and in emeralds in 1798 and was isolated as the metal independently by Friedrich Wöhler and A.A. Bussy in 1828.
