This piece nailed someting really important about natural thresholds in biology. The Pompeii versus Herculaneum compairson perfectly shows how therapeutic dose is separated from toxicity by such a thin margin. I once dealt with calcium supplementation studies where we saw similar nonlinear effects past optimal levels. The concept that ancient water sources could create these divergent health outcomes in neighboring populations adds a really practical dimension to volcanic chemistry most people never think about.

Let me post up my Lithium in water supplies PToDM. There are some interesting studies on crime in communities with lithium dissolved in their water supplies, too.
