Deeply concerned about slightly elevated levels of lead in range staff
Probably 5x boosted
Notice that nobody will quantify "Elevated" , or "above normal"
How about some numbers instead of Media speak for the shock value.
Were the lead levels in the dangerous range? And only half of the staff?
Was something besides employment contributory?
As Stack_exchange says lead is dealt with routinely in industry through proper testing and mitigation IF a problem is found.
Air sampling is a regular event in the shipyard business and there are any number of labs that can do it.
The range needs to be fully operational as on a normal weekend for valid sampling, however.
Anything less would be useless.
Mitigation might be as simple as wearing the appropriate HEPA respirator, or reducing hours worked.
