Public Health Danger In The Shower?

by Jon Henshaw

Wake Forest University School of Medicine is reporting that Manganese (Mn) may be giving 8.7 million people brain damage from showers. If there’s enough Mn in the water, they say a 10 minute shower can do damage after it’s inhaled through aerosolized water (aka steam).

Manganese (Mn) is an essential trace element but is neurotoxic at high doses. Showering with Mn-laden water has never been evaluated as a central nervous system (CNS) delivery vector for Mn, even though intranasally administered Mn in laboratory animals circumvents the blood–brain barrier and passes directly into the brain via olfactory pathways.

…Long-term shower exposure to Mn-laden water may pose a significant risk for CNS neurotoxicity via olfactory uptake in up to 8.7 million Americans. If our results are confirmed, regulatory agencies must rethink existing Mn drinking water standards.
