Although beryllium has been studied in animals and humans (Witschi 1968, 1970; Muller-Quernheim 2005), not enough studies have been conducted regarding its toxicity in plants or its biochemistry within plants.Some previous studies reported that beryllium is a nonessential and phytotoxic element that impairs the growth and yield of …
Dust control is the primary preventive measure. If the rock you mine contains beryllium, follow proper clean-up and housekeeping measures to keep the dust from becoming airborne. • Use water to suppress the dust. • Wet sweep or use a vacuum with a high-eficiency filter that is specifically designed to capture beryllium dust.

The rule reduces the PEL for beryllium to 0.2 micrograms per cubic meter of air (μg/ m3) averaged over 8 hours, and establishes a short-term exposure limit (STEL) for beryllium of 2.0 μg/m3 over a 15-minute sampling period. Employers must use engineering and work practice controls to prevent excessive beryllium from becoming airborne where ...
Abstract. Exposure to beryllium remains a significant occupational hazard, clinically resulting in berylliosis, or chronic beryllium disease (CBD). This scarring lung disease is an interstitial lung disease characterized by granulomatous inflammation that affects 2–10% of those exposed. Serving as a model for other granulomatous disease, …
Beryllium oxide is used to make ceramics for electronics and other electrical equipment because of its heat conductivity, high strength and hardness, and good electrical insulation. Metal slags and fly ash (a byproduct of coal-fired power plants) may also contain trace amounts of beryllium (considerably <0.1% by weight).
