NCIt definition : A white colored, crystalline, inorganic compound that emits toxic fumes of beryllium
oxides upon heating. Beryllium hydroxide is mainly used to produce beryllium metal
and alloys. Inhalation exposure to its dust irritates the nose, throat and lungs and
can cause pneumonitis. Prolonged exposure can result in a chronic beryllium disease
called berylliosis causing granuloma and fibrosis formation in the lungs. Beryllium
is associated with an increased risk of developing lung cancer. (NCI05);
