Dr. Greger's articles are usually pretty good, but I've never heard of plants being able to pull up Lead from the soil.

Written By Michael Greger M.D. FACLM on June 5th, 2018
China burns about half of the world’s coal, spewing heavy metals such as mercury and lead into the atmosphere that affect the development of neighboring children. What if you don’t live in China or eat anything produced there? You could still be exposed to the mercury that settles in the oceans if you eat fish and other seafood. What if you drink something from China? Tea. China is one of the world’s biggest tea exporters, but their rapid industrialization has raised concerns about contamination with lead, a toxin that can affect almost every organ in the body. The more lead there is in the soil, the more lead there is that ends up in the tea leaves. And, the closer to the highway the tea is grown, the higher the lead levels. This suggests that leaded gas, which wasn’t banned in China until the year 2000, may be playing a role in the contamination of tea grown there.
