In last decades
there has been an increase in consumption of bottled mineral waters (BMW)
instead of tap water due to recent problems about tap water’s resources
depending on safety concern in all over the world.  Although bottled waters are often remarked as
safer than tap water, at some cases this approach may be not true especially if
those products contain higher levels of trace elements and some toxic heavy
metals.

BMW always
contains various minerals and trace elements. We know that some of these
elements such as selenium (Se) zinc (Zn) are essential for living organisms and
they are required for normal biochemical reactions. On the other hand, other
toxic elements, called toxic heavy metals (THM), potentially could be harmful
for human health when they present in excessive levels in these products. Thus,
chronically exposures to these elements such as lead (Pb), cadmium (Cd)
associate with chronic illness and
cancers. In this respect, for the evaluation of probable health
risks arising from these elements depend on a special point that is determine
of those elements in interesting products. Based on above information we aimed
in this study determining the THM
levels in natural mineral water (NTM) and fruit-flavored BMW sold in local markets
in Turkey. Also, we investigate whether the geographic location, which is about
production site, effect the metal level or not. Arsenic (As), cadmium (Cd), chromium (Cr), lead (Pb),
nickel (Ni) are determined in 93
samples belong to 13 different firm by using Graphite Furnace
Atomic Absorption Spectroscopy (GFAAS) technique. The samples consisted of 27
natural mineral water and 66 flavored (strawberry, lemon, cherry). Our results
showed that the toxic metal levels determined in the samples don’t contain any
risk in terms of toxicological aspect if they are consumed. However, it is very
important that similar studies within more extensive sample should repeat in
certain periods in terms of protection of public health and observing the
subject recently.
