FWIW, I compiled 35 Blackstone Lab tests that I have found online. Here are the current averages of what i've found (which are higher than Blackstone's own universal averages):
Aluminum: 5
Iron: 12
Copper: 6
Lead: 13
You're right in there with the online averages but a tick higher on lead. FWIW out of the 35 analysis', 10 of them had a higher lead count than you.
Not sure if that makes you feel any better...
