Magnesium Chloride - The
Great Salt Lake - Toxic Mercury
Toxic Mercury Lurking in Great
Salt Lake - "Sea Water"
There is a growing concern of Mercury
in magnesium products coming from the Great Salt
Lake. Federal scientists studying the lake have
found some of the highest levels of mercury ever
measured anywhere. Why? Because "Mercury is
a highly toxic element that occurs naturally in
the environment but also has been introduced through
human activity. Utah's industrial and mining past
has exposed the lake to mercury pollution."...
"We thought we would find some high levels
of methylmercury," said David Naftz, the USGS
research hydrologist who is heading the Great Salt
Lake project, "but not some of the highest
(the USGS) has ever found."
According to water tests done by
Kennecott Utah Copper last summer, two years after
samples that triggered alarms about mercury throughout
Utah. Kennecott's samples taken in the lake's "deep
brine layer," about 20 feet below the surface,
were as high as 80.5. Krabbenhoft noted that .5
is considered a "level of substantial concern".
Preliminary analyses shows that methylmercury levels
in the "deep brine layer" are among the
highest ever measured by the USGS. The deepest waters
of the Great Salt Lake may contain even more toxic
mercury than previously known.
Serious concerns have arised about
purchasing products coming from the Great Salt Lake.
Companies making claims about purity and the absence
of mercury should be reviewed.
USA Today's Story - "Researchers
Study Mercury in the Great Salt Lake"
years ago, in an alarming finding, U.S. Geological
Survey tests showed the lake had some of the highest
mercury readings ever recorded in a body of water
in the United States. The
state (of Utah) warned people not to eat certain
kinds of ducks because of the mercury.
