Is Manganese Damaging Your Brain – or Your Child’s?
Your body needs tiny amounts of manganese to function properly, but elevated levels can be toxic, especially in children. The heavy metal has been linked to developmental and brain problems in kids, as well as to Parkinson’s-like neurological conditions.
Now, researchers at the University of California, Riverside, have discovered that underground drinking water in certain parts of the United States and three Asian countries – Bangladesh, Cambodia, and China – may contain high levels of manganese.
The potential problem appears to be huge: More than 41 million people in 26 U.S. states rely on the glacial aquifer water system where the researchers found elevated manganese levels. Groundwater can be contaminated with a number of heavy metals, including arsenic, which has been subject of several studies evaluating water safety.
