Chronic lead absorption. Result of poor ventilation in an indoor pistol range.
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 100 mug/100 ml, free erythrocyte protoporphyrin levels greater than 450 mug/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.
