Surpassed only by water, tea is the second most consumed beverage worldwide. When boiled tap water is used to brew tea, residual chlorine in the water can react with tea compounds to form disinfection byproducts (DBPs). Researchers measured 60 DBPs in three types of tea, unexpectedly finding lower levels in brewed tea than in tap water. However, they also detected many unknown DBPs with uncertain health effects.
Although disinfection is important to ensure drinking water safety, a downside is DBP formation. Tea contains about 500 compounds, including polyphenols, amino acids, caffeine and others, that can react with chlorine to form DBPs, some of which have been linked in epidemiological studies with cancer and adverse birth outcomes. In addition, DBPs can form from reactions with compounds in the tap water itself. Susan Richardson and colleagues wanted to conduct a comprehensive survey to measure 60 known DBPs in three green and black teas popular in the U.S.
The researchers brewed the teas and then measured the compounds using gas chromatography-mass spectrometry. Levels of the 60 DBPs were higher in tap water than in the brewed teas, likely because many compounds evaporated or were absorbed by tea leaves. However, the 60 known DBPs comprised only 4% of the total organic halogen in tea, indicating that the majority of these compounds in tea are uncharacterized. The team identified 15 of these compounds -- which likely form from the reaction of chlorine with natural phenolic and polyphenolic precursors in tea leaves -- for the first time in the beverage. Although no "safe" levels have yet been established for most DBPs, for the ones that are regulated, an average person would need to drink 18-55 cups of tea per day to exceed the limits established by the U.S. Environmental Protection Agency, the researchers say.

I drink a lot of tea and herbal teas. I get my water from my well.
I saw Miley with a BB gun looking for right wing extremists
Sorry
People eventually die from drinking water.
Well water eliminates your issue.
I grew up on well water.
I use spring water for my tea and I don’t boil it! I do buy British tea. Pretty snobby but so much better than any other I’ve tried. I drink green tea too.
I find that using water containing Chlorine and/or Floride to brew tea makes it unpalatable anyway.
there used to be a tea...Nabob tea....best in the world.....Kraft bought the company and discontinued this tea....figures...
If you are drinking water from the tap you are poisoning yourself. We filter every drop we consume through a Berkey water filter. It takes out everything. Best $215 we ever spent.
It also eliminates the problem of breathing in chlorine vapors when I take a shower, and I'd expect that to be a bigger health issue for people than what chlorine doesn't boil off from the water that they use when they make tea.
are these bad things measured n PPT - parts per trillion?
Drink untreated water in the field, see what happens...
One year I decided to review the water testing results the city was required to post and I noticed they were over the limit for chloramine. It made me call them to register a complaint, as the water came from wells and not a lake, so no algal blooms needed to be corrected.
I believe it had been an accidental excessive increase for a period of time.
I, and all of my neighbors for many miles drank “untreated water” from wells, and our water all checked out with the occasional testing (aside from an occasion or two with higher nitrites from fertilizer used in the fields, I believe).
Why sorry? it’s not your fault the chlorine reacted with the tea to give you hallucinations. You didn’t know.
To paraphrase Hugo Chavez, does it smell like the Devil was just standing here?
(sulfur smell)
It’s always something!
I only drink grain alcohol and rain water. Fluoridating the water is a Communist conspiracy trying to rub us of our precious bodily fluids.
Not at all.
Maybe it’s location, but down in FL outside of Jax, my friends water smelled like sulfur...
