Scientists in Germany have found that water in many commercially sold plastic bottles is contaminated with chemicals which act like female hormones in the body.
The study found that waters in PET plastic bottles had around twice as much estrogen contamination as those in glass bottles. Before you think it may be a water processing or filtering issue in Germany only, think again: the estrogen comes from common plastic bottle ingredient bisphenol A, which leaches out of the plastic bottles.
The only bright side: only 12 out of 20 brands tested had a serious issue, indicating that it may have some relationship to how each bottle is manufactured.
A scientist told The Local that it’s not yet known whether the water contamination could present a health risk.
