Three cases of mild lead poisoning were discovered among instructors at an indoor pistol range. These cases were characterized by blood lead levels greater than 100μg/100 ml, free erythrocyte protoporphyrin levels greater than 450μg/100 ml of red blood cells, abdominal pain, and, in one instance, by slowing of motor and sensory nerve conduction velocity. Exposure to airborne lead produced during revolver-firing and bullet-molding accounted for the lead absorption. Ventilation in the range was inadequate. (<i>JAMA</i>234:394-397, 1975)
