The continued occurrence of chronic beryllium disease (CBD) suggests the current occupational exposure limit of 2 microg beryllium per cubic meter of air does not adequately protect workers. This study examined the morphology and measured the particle surface area of

At the facility studied, only two air samples out of 110 were above the detection limit, and none was close to the California PEL. Even though we found no beryllium levels close to the PEL, the facility could still easily

Beryllium metal and its oxide and alloys are materials of industrial significance with recognized adverse effects on worker health. Currently, the degree of risk associated with exposure to these materials in the workplace is assessed through measurement of beryllium aerosol

The structure and harmonic vibrations of Be(n)O(n) (n=3-10) clusters have been investigated using density functional theory. All structures are found to be cumulenic D(nh) rings (equal bonds, alternating angles), with one intense out of plane mode and three infrared-active degenerate
