I have a question regarding firing ranges. My son is almost 15 years old and is interested in shooting high caliber rifles at a local outdoor firing range. As you well know, typical rifle ammunition is lead based. It goes without saying that he may readily ingest microscopic amounts of lead dust/vapor that are likely blowing around in the environment of the rifle range. Would these extremely small ingestions pose any developmental brain threat to a 15 year old? Also, there is plenty of data regarding the brain development issue in young children. At what age can a parent no longer be concerned about lead and brain development? I recognize that lead can cause brain related symptoms in adults, but these would be different from the brain development concerns of children. I find very little written about lead and the teenage brain. Any information you can provide will be appreciated.
