Drinking and tap water supplies in
many geographic areas contain chromium. Certain contaminants, such as
hexavalent chromium(chromium-6), steel and pulp mills, a metal used in metal
processing, and the tanning industry, aren't removed by standard tap filters.
Acidic environments with high organic content lend wings to the reduction of
chromium-6 to nontoxic trivalent chromium(chromium-3). Public health worries
are centered on the presence of chromium-6 that is classified as "likely
to be carcinogenic to humans" by the U.S. Environmental Protection
Agency(EPA). In addition to this chromium-6 in drinking water has been linked
to certain stomach cancers. Exposure of animals to chromium-6 in drinking water
induced tumors in the alimentary tract, with responses in the mouse small
intestine. The widest form of DNA damage induced by chromium-6 is Cr-DNA
adducts, which cause mutations and chromosomal breaks. Otherwise, chronic
iron(Fe) overload results primarily from genetic disarray characterized by
increased iron absorption and from diseases that require frequent transfusions.
In this study, 12 spring waters and 7
tap waters analyzed. Inductively Coupled Plasma-Mass Spectroscopy(ICP-MS)
system was utilized for metals concentration in spring and tap waters. Furthermore,
Ion Chromatography(IC) system was evaluated for anion and cation determination
in spring and tap waters. The chromium levels were above the limit values in
the tap waters, moreover, above the limit values in 25% of the spring waters
and proximate to the permissible limits in 75%. Therewithal, the iron
concentrations in tap water, both in spring water, were above the permissible
limits.
People in Yozgat city drink
chromium-polluted tap water, much of it likely in the cancer-causing hexavalent
form. Moreover, people here also use tap water to prepare meals. Given the
scope of exposure and the magnitude of the potential risk, we believes require
public water suppliers to test for it. However, we believe that it is necessary
to support the independent bodies like ours(BOZOK UNIVERSITY-BILTEM-TOXICOLOGY
LABORATORY) to carry out analyzes at certain intervals.
Key Words: chromium, iron, drinking water, toxicity
