Metals and the Mind - The Weston A. Price Foundation

Mar 03, 2019· Aluminum is a very common metal, comprising up to 14 percent of the earth’s crust, so it is in the dust and in the air. Aluminum is also an additive in anti-perspirants. I have a theory that in warm climates, where people use a lot of anti-perspirants, they are exposed to a lot more aluminum than people living in colder climates.

History of Metals Timeline Infographic

What Is the Current Price of Iron Per Pound? | Reference

The current daily price of iron fines as of August 2014 was $92.61 per ton, which equates to approximately 0.04 cents per pound. Scrap iron prices per pound vary depending on the facility purchasing the iron and any daily fluctuations in pricing. Scrap iron is typically bought by the ton, with per pound rates based on the ton rate.

Are Heavy Metals Toxic? - Baseline of Health

In summary, don’t have a knee jerk reaction to the label “heavy metals.” (Both calcium and iron are technically heavy metals.) Yes, obviously, when it comes to “toxic” heavy metals, less is better than more. But the issue is far more nuanced than a simple label–or even nuers on a chart for that matter.
