AABEN,
The sky is not falling, no matter what the "internet" tells you. The original question regarded "reloading ammunition in a basement". That was the question I answered, and for your information, I've studied lead contamination thoroughly, from real experts, not the internet, where every Tom, Dick and Harry feels they are an "expert". My conclusions are based on science, and hands on experience, not internet lore.
My EXPERTS work for the Environmental Protection Agency (EPA) and the National Shooting Sports Foundation (NSSF), and you can look both of those up on the internet if that will make you feel better. Both of those agencies have studied lead contamination, it's causes and the results, along with courses of prevention and how to mitigate contamination once it occurs. I was responsible for writing the Best Management Practices manual for our range, which was recognized by the EPA as one of the most thorough and comprehensive management plans for lead issues in the nation, and was put up for a national award for it.
If you choose to live in a bubble, that's your choice, but don't try to tell me what's correct about lead issues when you have no idea of the amount of study I've done on the issue. You might try doing a search on this forum and look up this subject in past threads for a better understanding of the whole issue before you start jumping down my throat....
Now if you want to talk about bullet casting, that's a whole other issue, and yes, I do that, too. A lot of bullet casting, like in many, many thousands of bullets per year. I don't wear a HazMat suit when I'm casting, but I do take the precautions the industry and regulatory agencies proscribe. And my lead level is still well within the normal range, according to my last blood test.
And I'll repeat, your post didn't make any sense in the context of the OP's question.
Hope this helps.
Fred
