The requirements of beryllium monitoring are discussed. Emphasis is placed on developing an analytical procedure which is rapid. simple to operate, of adequate sensitivity. and of reasonable accuracy. For air analysis, berylliumbearing dust is collected on a membrane filter: the beryllium is obtained in solution and determined spectrophotometrically. using aurine tricarboxylic acid (aluminon) as reagent. Interference owing to other metals is avoided by the addition of suitable complexing agents. A sensitivity of .0.1 mu g beryllium can be achieved. (auth)
