Brewing tea removes lead from water
That comforting hot cup of tea—or refreshing glass of iced tea on a hot summer day—could help reduce the amount of toxic metals in drinking water, according to a new paper published in the journal ACS Food & Science Technology.
Brewing tea reduces toxic heavy metals in drinking water, study finds
In a new study, Northwestern University researchers demonstrated that brewing tea naturally adsorbs heavy metals like lead and cadmium, effectively filtering dangerous contaminants out of drinks. Heavy metal ions stick to, or adsorb to, the surface of the tea leaves, where they stay trapped until the used tea bag is disposed of.
Tea Leaves Can Steep Away Lead, Study Finds
Researchers found that compounds in black and green tea leaves acted like “little Velcro” hooks on lead molecules.
Brewing tea removes harmful toxins from water, study finds
The process of brewing tea was shown to remove toxic heavy metals from drinking water in a new study from Northwestern University in Illinois. The researchers explain the findings to Fox News Digital.
Brewing tea can remove lead and other heavy metals from water, new study finds
Tea leaves can remove heavy metals such as lead, cadmium and chromium from water. And steeping time has the biggest impact.
Tea brewing benefits: It may help filter out heavy metals, study finds
Brewing tea may help filter lead from water, but it depends on the type, grind, bag and steep time, a new study has found.
Tea can absorb lead, other harmful metals, Northwestern University scientists find
The Evanston researchers discovered brewed black, green and other tea leaves can remove dangerous contaminants as the leaves act like a sponge.
