Thread: Help Offered – Range Contamination

It is probably more a case of "what you don't know you don't know".

One of the classic cases of lead poisoning was here Lead poisoning of Port Pirie children: a long history of looking the other way

I served my time in a fertiliser works. The sulphuric acid making plant was all made of lead, huge quantities of lead sheeting, lead pipes, special pumps with lead impellors etc. (great for me as I was into BP shooting then). The guys that worked with the lead were called "lead burners" - was a recognized trade way back. They were regularly blood tested for lead absorption. I can remember on the odd occasions members of that department being stood down from working with lead due to getting excess reading in their blood tests. Stood down until subsequent blood tests showed level had dropped. And of course standards were pretty slack back then. Look how we used to treat asbestos.

My smallbore club (long since folded) shot in a war memorial hall, thru under the stage. The mound was the highly polished hall floor. I used to see dusty powder out in front of the mound at the end of a night's shooting. I used to assume it was all burnt powder but have often wondered if there was any minute lead dust in it as well. And despite regular cleans our lead traps and the area were a mess with lots of dust everywhere. They backstops were angle plates which directed the lead into sand traps but the bullets striking the plates inevitably generated lead dust.

And yes my current house roof although having no lead head nails has lead flashing, and we are on tank water.
