In the US, about one million law enforcement officers train at indoor firing ranges, 20 million citizens practice target shooting, and 16,000-18,000 indoor firing ranges exist.
We reviewed 36 studies that measured blood lead levels at shooting ranges. The studies were from 15 countries, but most were from the US. About two-thirds of the studies looked at people who used shooting ranges for work.
We found blood lead levels of at least one of the participants in 31 of 36 studies had an elevated blood lead level. This means more than the current adult blood lead reference level of 5µg/dL, or 5 micrograms of lead per decilitre of blood, as recommended by the US Centers for Disease Control and Prevention and National Institute of Occupational Safety and Health.

So in 5 of the studies no one had raised lead levels, not a great point.
"At least one of the participants" out of how many?
Does "at least one" mean 1/30 people or 25/30 people.
What do the people do for a living? Outside of that? Other environmental factors?
Basically this said "we tested a bunch of shooters and some had raised lead", and seemingly the majority did not.
Meaningless.

Old thread I know but to keep it all in one, I have a hypothetical question.
Say a mate of mine has just been tested. Results are .60 umol/L and 12.4 ug/dL Up from last year. Health Dept sent a letter asking why.
Now old mate shoots a Black Powder cartridge rifle and cast his bullets under the house with a fan blowing gently sideways to keep the fumes away. He has been casting less than last year but blood count is still higher.
He does not want to quit shooting and casting.
Any ideas on what is happening and why and what else he can do to reduce the count.?
