Purpose: Beryllium is known to have adverse health effects and is classified as carcinogenic to humans. However, data on systemic beryllium exposure in humans are rare and especially human toxicokinetics are largely uncharted. As such, the first reported multi-annual course of blood and urine concentrations after a high exposure scenario …
Other agencies have taken action in re-evaluating their occupational exposure guidelines for beryllium. ... The primary health concerns related to beryllium—sensitization, CBD, and lung cancer—make up the bulk of the literature. A much smaller database was found on other toxicity end points, such as reproductive and developmental effects. ...

Beryllium is a steel-gray metal that is quite brittle at room temperature, and its chemical properties somewhat resemble those of aluminum. It does not occur free in nature. Beryllium is found in beryl and emerald, minerals that were known to the ancient Egyptians. Although it had long been suspected that the two minerals were similar, …
This Guideline provides the clinical criteria diagnostic for beryllium sensitization and chronic beryllium disease (CBD; old term = berylliosis), based on the latest available medical literature and consultation with leading experts in the field. This Guideline does not address exposure prevention, workplace safety, or treatment.
Beryllium is a lightweight metal with unique mechanical and thermal properties that make it ideal for use in many applications and industries including defense, aerospace, telecommunications, automotive electronics, and medical specialties. Beryllium is a naturally occurring metal found in several minerals. It is most commonly extracted from ...
Your lungs respond to beryllium by developing collections of cells known as granulomas, which may eventually cause scarring. This scarring reduces your lungs' ability to function. As the inflammation response continues, over time, symptoms may eventually appear, including: Difficulty breathing/ shortness of breath.
Prognosis. Prevention. Chronic beryllium disease is lung inflammation caused by inhaling dust or fumes that contain beryllium, a metal that is used in small amounts in many industries. People with chronic beryllium disease may gradually develop coughing, difficulty breathing, fatigue, and night sweats. Acute beryllium disease is now rare ...
The committee has reviewed the literature describing exposure to beryllium to provide a basis for examining questions relevant to the identification of exposure-response relationships and the development of health-protection standards. Worker-protection standards are the focus of this effort, but an understanding of natural background …

Beryllium usually affects the respiratory system, although it can affect other parts of the body as well. Listed below are different types of illnesses or health effects associated with beryllium. The body develops hypersensitivity to beryllium. No symptoms, but the body identifies beryllium as foreign.
Symptoms of acute beryllium disease include irritation of the lungs, nose, and throat, as well as trouble breathing and tiredness. People with chronic beryllium disease develop lesions (masses) in the lungs that can lead to scarring. They may experience chest pain, cough, and/or shortness of breath. Skin contact with beryllium may cause an ...
This standard means this beryllium standard, Section 5205. (c) Permissible Exposure Limits (PELs). (1) Time-weighted average (TWA) PEL. The employer must ensure that no employee is exposed to an airborne concentration of beryllium in excess of 0.2 μg/m 3 calculated as an 8-hour TWA. (2) Short-term exposure limit (STEL).
DOE G 440.1-7A, Implementation Guide for use with 10 CFR 850, Chronic Beryllium Disease Prevention Program; Safety and Health Regulatory and Policy Response Line; Beryllium-Associated Worker Registry - The goal of the registry is to determine the incidence and prevalence of beryllium sensitization and chronic beryllium disease …
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 ...
Exposure Evaluation and Controls. Exposure to beryllium via inhalation of airborne beryllium or dermal contact with beryllium-containing dust, fume, mist or solutions can cause health effects. The following resources provide information on exposure limits and analytical methods used to evaluate workers' beryllium exposure.
The United States Occupational Safety and Health Administration (OSHA) has set the permissible exposure limit of beryllium to 0.2 micrograms per cubic meter of air, …
Biomonitoring studies on levels of beryllium provide physicians and public health officials with reference values so that they can determine whether people have been exposed to higher levels of beryllium than are found in the general population. Biomonitoring data can also help scientists plan and conduct research on exposure and health effects.

Our vision and mission are the attainment by all peoples of the lowest possible burden of water and sanitation-related disease through primary prevention. About us.
Beryllium is a naturally occurring element that is extracted from ores and processed into metal, oxides, alloys, and composite materials. Industrial use of beryllium, such as machining metal parts, can lead to BeS and CBD (1). The major applications of beryllium are in automotive electronics, telecommunications, computers, aerospace,
