Human urinary and blood toxicokinetics of beryllium after

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 …

Berylliosis (Chronic Beryllium Disease): Symptoms

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.

Beryllium Disease

Beryllium Toxicity: Patient Education Care Instruction Sheet

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.

Beryllium | ToxFAQs™ | ATSDR

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 ...
