CONCLUSIONS

1. Rep. Moldova records a more important tea consumption than Romania.

2. Even if we found a lower level of fluoride in Moldova marketed teas, its toxic effect is highly amplified by the large concentration

of fluoride in country's drinking waters.

3. In Romania the risk of fluorosis increases

at consumption of more than 2 cups of tea per

day and it’s higher in children.

4. We recommend a moderate tea consumption,

especially in areas with increased fluoride levels

in drinking water.
