Exposures to beryllium (Be), even at extremely low levels, can cause severe health effects in a percentage of those exposed; consequently, occupational exposure limits (OELs) promulgated for this element are the lowest established for any element. This work describes the advantages of using highly alkaline dye solutions for determination of Be in occupational hygiene and environmental samples by means of an optical molecular fluorescence technique after sample extraction in 1-3% (w˖w) aqueous ammonium bifluoride (NHHF). Improved attributes include the ability to further enhance the detection limits of Be in extraction solutions of high acidity with minimal dilution, which is particularly beneficial when NHHF solutions of higher concentration are used for extraction of Be from soil samples.

Purpose: The purpose of this descriptive correlational study was to describe the coping behaviors used by Army wives during deployment separation, the perceived effectiveness of the coping behaviors used, and the correlation between the two variables.

Data Sources: A secondary analysis was conducted to examine coping use and perceived effectiveness, measured by the Jalowiec Coping Scale (JCS), in a sample of 102 Army wives surveyed during deployment separation.

Conclusions: The most used coping subscales from the JCS were the optimistic and supportant and the most effective were the supportant and confrontive.

Analytical methods for the determination of trace beryllium in soils are needed so that anthropogenic sources of this element can be distinguished from native (background) levels of beryllium. In this work, a collaborative interlaboratory evaluation of a new extraction and fluorescence-based procedure for determining beryllium in soil samples was carried out to fulfil method validation requirements for ASTM International voluntary consensus standard test methods. A Canadian reference material, CCRMP Till-1 soil, with a background beryllium concentration of 2.

Beryllium metal and beryllium oxide are important industrial materials used in a variety of applications in the electronics, nuclear energy, and aerospace industries. These materials are highly toxic, they must be disposed of with care, and exposed workers need to be protected. Recently, a new analytical method was developed that uses dilute ammonium bifluoride for extraction of beryllium and a high quantum yield optical fluorescence reagent to determine trace amounts of beryllium in airborne and surface samples.
