The study, titled, “Environmental Manganese and Cancer Mortality Rates by County in North Carolina: An Ecological Study,” was published online last month by Biological Trace Element Research.
Lead researcher John Spangler, M.D., professor of family and community medicine at Wake Forest Baptist, found that groundwater manganese appears to be positively associated with total cancer, colon cancer and lung cancer death rates, while airborne manganese concentrations appear to be inversely associated with total cancer, breast cancer and lung cancer death rates.
“People need manganese in trace amounts, but if you get too much of it, manganese can be dangerous,” Spangler said. “It’s my hope that the impact of this study will be to spark additional interest and research. This really just raises the concern that something may be going on and argues for further research into these issues.”
To determine whether environmental manganese is related to cancer at the county level in North Carolina, Spangler conducted an ecological study using data from the North Carolina State Center for Health Statistics, North Carolina Geological Survey, U.S. Geological Survey, and U.S. Census.
He found that airborne manganese was associated at the county level with an 14 percent decrease in total cancer deaths, a 43 percent decrease in breast cancer deaths and a 22 percent decrease in lung cancer deaths. Additionally, Spangler found there was up to a 28 percent increase in county-level colon cancer deaths and a 26 percent increase in lung cancer deaths at the county level related to elevation of manganese in groundwater as opposed to air.
“That’s pretty astounding. These are the first data we know of to document a potential relationship between environmental manganese and population-level cancer death rates,” Spangler said. “The positive association between groundwater manganese and specific cancer mortality rates might be a function of the high concentrations measures, while the inverse relationship between air manganese and death rates might point toward adequate (e.g. healthy) county-level manganese exposures.”
Spangler points out that because manganese now replaces lead in gasoline globally, the amount of manganese in the environment is increasing and may worsen the groundwater concentration numbers in the future. The effects of these ecological findings should be confirmed at the individual level or in animal models, he said.

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
