millwrights at the plant were at risk for direct exposure to beryllium through machining copper–beryllium (Cu–Be) alloy tools with 1–2% beryllium content, such as chisels, scrapers,and screwdrivers. These tools were machined using belt sanders in one of two tool and die shops. Workers also reported that some workers occasionally honed ...

Beryllium in soil can pass into the plants grown on it, provided it in a soluble form. Typical levels in plants vary between 1 and 40 ppb, too low to affect animals which eat these plants. Beryllium is found in 30 different minerals, the most important of which are bertrandite, beryl, chrysoberyl, and phenacite.
Abstract. Objective: Workers at a beryllium ceramics plant were tested for beryllium sensitization and disease in 1998 to determine whether the plantwide prevalence of sensitization and disease had declined since the last screening in 1992; an elevated prevalence was associated with specific processes or with high exposures; exposureresponse relationships differed for longterm workers hired ...
Dec 31, 2015· Background. Inhalation of beryllium (Be) has been associated with 2 pulmonary syndromes, which are an acute chemical pneumonitis and a granulomatous lung disease known as chronic beryllium disease (CBD), or berylliosis. In acute beryllium disease, the metal acts as a direct chemical irritant, causing a nonspecific inflammatory reaction...
