Inorganic lead concentrations ranged from 3.4 to 12 milligrams per cubic meter (mg/cu m) while firing standard 148 grain ammunition. Exposures ranged in duration from 7 to 10 minutes. Corresponding 8 hour time weighted average (TWA) concentrations of lead in the shooters' breathing zones ranged from 0.05 to 0.25mg/cu m, with a mean of 0.16mg/cu m, compared with the OSHA 8 hour TWA exposure standard for inorganic lead of 0.05mg/cu m.
