Tea is the second most popular soft drink in world after drinking water. And although it is also considered one of the most useful, scientists have discovered a new danger when brewing it in tap water.

In a new study, scientists analyzed several brands of the most popular teas. As a result, it was found that residual chlorine in water can form disinfection byproducts (PPDs) by reacting with compounds in the drink.

According to the researchers, because tea contains many different substances (many of which are beneficial), not least chlorine can play a role in the cup.

Scientists also noted that measured PPD levels in the tea itself were lower than in tap water. In particular, their number was 12%, while another 88% came from water. “The total amount of organic halogens in tea is almost doubled compared to tap water, while 96% of halogenated PPDs are unknown,” the scientists added. remember the purity of the water that is used every day.
