In february I´ve started a thread that is actually a blog. It starts out: If NO is an issue, than Mn is (shown two times, 2005 and 2006, #16), if nitric oxide is involved, then manganese is of importance.
Later on I did some wider speculation and its well known momentums fit into each other very well,
including a speculation on one single momentum (therefore written very small in #30)
Now I recognized that its implicated danger of "non-toxic" Mn has been found seemingly in reality, but please notice also the inverse relationship, it might be not all clear.
5. Conclusion
The mean concentration of Mn in drinking water in Huai’an city was much higher than the concentration according to the national standards for drinking water quality. And the ratio of superscale is very high. Mn concentration is carcinogenic to people, which correlates with cancer incidence and mortality. Measures for mental pollution prevention and control must be taken immediately.
4. Disscussion, ...
Another important finding was that Mn concentration in drinking water in Huai’an city correlated with cancer incidence and mortality. In our city, for a 1 μg/L increase in Mn concentration, there was a corresponding increase of 0.45/105 cancer cases and 0.35/105 cancer deaths. At first glance, this finding appears to be unbelievable. A large ecological study was carried out in North Carolina, and they also found manganese concentration in groundwater correlate with cancer mortality [12]. There are also some other studies showed the relationship between Mn and cancer. Mn is a component of the important antioxidant enzyme, manganese peroxide dismutase (MnSOD) which mitigates the oxidative damage from reactive oxygen species, one pathway thought to participate in carcinogenesis, such as lung cancer and breast cancer [13, 14]. An inverse relationship between breast cancer and hair manganese was documented [15, 16].
Though World Health Organization (WHO) found among the general population, the average estimated Mn intake from drinking water is substantially lower than the intake of Mn from the diet, typically 20 μg/d [17], our findings point out that mental pollution should be taken into account. Factors such as age, chemical species, dose, route of exposure, and dietary components influence both the absorption and bioavailability of manganese in human [18–21]. Thus the measures for mental pollution prevention and control should be of diversity.

Edit: I changed the titel from "proven" to "confirmed" (originally I had "shown").
I put the thread because this famous and serious issue fits in my Mn theory of ME/CFS which I tried to explain in http://forums.phoenixrising.me/index.php?threads/my-low-manganese-diet-my-success-so-far.57677/

The follwing study found for a second time that manganese is correlated with cancer.
