Beryllium complexes salicylic acid

Beryllium poisoning is treated with large doses of sodium salicylate, or smaller doses of aurine tricarboxylic acid. The latter, which has three salicylate moieties linked to a central carbon atom, does not assist the excretion of this metal, as salicylate does, but keeps it, in the tissues, as a very insoluble complex.
