Cold brew Green Tea / Heavy Metals / Lead ?

As stated in the article you posted, lead levels can vary depending on where your tea comes from and where the water you are brewing your tea in comes from. Their study also used oolong tea from China which are leaves that are older and has more possiblity of contamination. The Green and White Teas which are younger leaves would have less contamination. Japanese Green Tea has tested to have very little if any traces of lead in it. One link that I found helpful was : https://nutritionfacts.org/video/lead-contamination-of-tea/ Remember there is more than the tea to consider, the water used is also important. There are so many healthful effects of tea!! Well worth continuing to enjoy your tea. I hope this helps!!

I have not heard of this problem with lead in tea. I think it cannot be too widespread or more people would have heard this. To be honest the only problem like this I had heard of with tea was Japanese tea grown too close to the Fukoshima site of the meltdown. I am fairly confident there is no lead pollution in New York water especially Long Island where I live.
