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.
