Brewing tea removes lead from water (arstechnica.com)

Summary

A new study in ACS Food & Science Technology finds that brewing tea can help remove toxic heavy metals from water.

Researchers tested various tea types and tea bags, discovering that cellulose tea bags and finely ground black tea leaves were most effective at adsorbing metals like lead, chromium, and cadmium.

Longer steeping times significantly increased metal removal, with a typical three-to-five-minute brew reducing lead by 15%.

While not a global solution, tea consumption may passively reduce heavy metal exposure and its associated health risks.

Now we can choose between heavy metal exposure and microplastics due to teabags https://pmc.ncbi.nlm.nih.gov/articles/PMC10389239/

Count me as Team Microplastics. I'll take the one with subtle, hard to define effects over very obvious toxicity.
