Lead poisoning can be dangerous to anyone. But it's especially harmful to children.
Their smaller, growing bodies make them more susceptible to absorbing and retaining lead.
Recently, kids and teenagers across the country have exposed themselves to the poisonous metals by participating in gun clubs.
The Seattle Times looked into the issue after unsafe levels of lead were found in blood tests of 20 young people shooting at a gun club in Vancouver, Washington.
As one of the teenagers recalled, "We would get lead on our hands and eat finger food."
The investigation also found that employees of the gun ranges were at risk and little was being done to monitor or ensure safety.
