Make money doing the work you believe in
And “high levels” isn’t even the point/necessary, possibly: chronic arsenic exposure at even low levels can produce “Ebola” symptoms like dramatic hemolysis. The fact that we can potentially map higher arsenic levels in the red areas thus strengthens the hypothesis lurking here.
Shedding the classical toxicology model (“dose makes the poison”) is long overdue…but all the researchers I knew who were driven to study the biological effects of low doses of toxins over time, and on different age/developmental groups, and at different times of the year, and under different types and levels of stress—they all got Shut It Downed. There are a few peer-reviewed publications still out there…on the topic of the interactive effects of various biocides and nitrates/nitrites alone and in combination (conclusion: N ramps up effects exponentially)…but the lid got slammed shut on the topic. I knew a couple epidemiologists who tried to approach the problem from that angle. Same result: no money, peer pressure, career injury, threats.
I’ve known three “alternative” (traditional) health care providers who were certain from observation/experience that arsenic, cadmium, and mercury could cause hemolytic reactions.
With arsenic the focus in the literature/PR is generally on cancer and kidney disease. That’s where the money is. I understand that the global health foundations/organizations are going big on building dialysis centers in sub-Saharan Africa. Here’s just one of many citations on the issue. You will see how the entire approach/model is aligned with TESTING and MARKERS and subsequent treatments of the usual sort. Not involving environmental factors.
