Beryllium and inorganic compounds of beryllium in air

The document is set out as follows: introduction (chemical and physical properties; toxicity; first aid; control; determination of beryllium-in-air concentrations); scope (range; limit of detection; precision; interferences; principle (Be dust and fume is collected on a filter which is then treated with 50% nitric acid. Subsequent treatment with concentrated sulphuric acid is necessary when samples of BeO are being analysed. The resultant solution is analysed for Be by atomic absorption spectrometry); reagents; apparatus; procedure. (U.K.)
