| Thirty-six bottled water samples representing water from around the world were analyzed for metal content by using flame atomic absorption spectroscopy. The analyzed metals were Ca, Na, Mg, K, Ni, Pb, Cr, Fe, Cu, Zn, Mn, Mo, and Al. Information on the source, water treatment method and listed contents for each bottled water sample were compared and contrasted with respect to the results found. While some bottled water samples listed zero mg Na per serving, results indicated that Na was present in the water sample. Other similar examples will be reported upon. |
