DIFFERENCES IN ALUMINIUM CONTENT OF VARIOUS TEA POWDERS (BLACK, GREEN, HERBAL, FRUIT) AND TEA INFUSIONS

European chemical bulletin, 2012
Trace elements play an important role in human health. Some trace elements are essential, but some are harmful – especially in higher concentrations. Aluminum is not considered as an essential element for human beings, but has, in contrary, been correlated with various human pathologies for example Dementia, Parkinson and Alzheimer disease.
