Lead
Lead doesn't stain the way iron does because it's not as soluble in water as
iron is, and the lead molecules are much heavier, making transport by water
much slower.
When lead was used for pipes carrying drinking water it was believed that it
was completely insoluble. Ttragically, this is not true.
If you want to see what happens to the human brain as a result of lead
poisoning, visit Euroope, especially the UK.
If you want a form of lead that is completely inert, find some that's been
saturated with sufluric acid. The resulting precipitate PbSO4 is chemically
inactive.
This is what forms in car batteries, rendering them un-rechargeable. The
lead in those batteries is referred to as being 'sulfated', by mechanics.
