The Beryllium Thread
I'm putting this in here so that it won't hang around the top of the lounge while I cut and paste information in to post after post.
This is part of my ongoing offseaon attempt to get us ranked on the first page of some search engine(s) when nerds search for "beryllium". Before you PM me with "Why?", the answer is simply that I am sitting around reading log files at work and cutting and pasting into this thread requires absolutely NO mental stress.

Beryllium is a light, hard, silver gray metal with unique properties such as strength, electrical and thermal conductivity, and resistance to corrosion (Stonehouse and Zenczak,1991). These properties have contributed to the use of the metal and its oxide in a wide variety of technological applications shown in Table 1 below (Weston et al., 2005). Recent estimates indicate that as many as 134,000 current workers in private industry and government may be exposed to beryllium in the United States (Henneberger et al., 2004). Some workers exposed to beryllium dusts and/or fumes develop may develop an immune response known as sensitization that can be detected in the blood with the beryllium lymphocyte proliferation test (BeLPT). Sensitized workers may have or may develop chronic beryllium disease (CBD), a slowly progressive respiratory disease characterized by the formation of lung lesions called granulomas. These granulomas and accompanying fibrosis cause impairment of the lung’s ability to expand fully and to oxygenate the blood. The rate of progression from less severe to severe disease can vary widely. There is no cure for CBD, although symptoms can be treated.

Since 1998, NIOSH has been conducting research in collaboration with the leading producer of beryllium and beryllium-containing products in the United States. The goal of this research is to prevent sensitization and CBD by developing a better understanding of the work processes and exposures that may present a potential risk for workers, and to develop effective interventions that will reduce the risk for adverse health effects. NIOSH also conducts genetic research on sensitization and CBD, independently of this collaboration.
