Hazardous Substances Data 7440-41-7(Hazardous Substances Data)
Toxicity Elemental Be and its compounds are very poisonous by inhalation or intravenous route. Chronic inhalation of beryllium dusts or fumes can cause a serious lung disease, berylliosis, after a latent period ranging from several months to many years. Inhalation of airborne dusts can also cause an acute disease manifested as dyspnea, pneumonitis and tracheobronchitis with a short latency period of a few days. Skin contact with soluble salts of the metal can cause dermatitis. Beryllium also is a carcinogen. There is sufficient evidence of its inducing cancer in animals and humans. It is one of the US EPA's listed priority pollutant metals in the environment.
