NCIt definition : An inorganic substance that contains the metallic element beryllium with excellent
thermal and electrical conductivity and is corrosion resistant. Beryllium compounds
are used in the electronics, automotive, aerospace, defense and nuclear industries.
Inhalation exposure to beryllium compounds can cause pneumonitis, and prolonged exposure
can result in berylliosis, characterized by occurrence of granulomatous fibrosis in
the lungs. Beryllium compounds are known human carcinogens and are associated with
an increased risk of developing lung cancer. (NCI05);
