Lead in tea

Just came across this link:

It is a Canadian site so I am not sure if it will be accessible to international people.

I do not agree with some of the comments in this news report but here is the gist of the report. The University of Alberta did a study on the amount of lead in 30 brands of store bought tea. They found that 73% of the teas had more than the acceptable level of lead for pregnant woman. This is a problem when combined with lead people absorb from other sources such as prenatal vitamins. The highest levels were in teas that came from China. One of the researchers reported that they believe the tea leaves absorb the lead from the air, soil, and water. The lead most likely coming from burning coal. (Of an interesting note, the researcher stated that tea plants have been found to concentrate lead, aluminum and floride in the leaves). They found that the Indian-sourced teas had the lowest levels of lead. The researcher said they recommend pregnant women drink no more than 3 cups of tea per day. There were no real recommendations for non pregnant people. They did not name the brands of teas they tested.
