Moreover, ACGIH® states, "Exposure to soluble beryllium salts (sulfate, ammonium carbonate, beryllium carbonate, and to a lesser extent, beryllium hydroxide) may occur during extraction of the metals from the ore (Deubner et al., 2001). These salts are considered the main source of beryllium sensitization during beryllium extraction" (ref. 29).

Beryllium dissolves readily in nonoxidizing acids, such as HCl and H 2 SO 4, but not in nitric as this forms the oxide and this behavior is similar to that of aluminium metal. Beryllium, again similarly to aluminium, dissolves in warm alkali to form the beryllate anion, Be (OH) 2− 4, and hydrogen gas.
