A study was carried out to explore the causes of the
chromium corrosion that specifically occurs in Russia, and the mechanism of corrosion of the
chromium plating was determined.
Supplying
chromium in the preformed complex organic form increases absorption, reduces variability in responses and negates the need for adequate dietary precursors (eg.
Prolonged or repeated exposure to hexavalent
chromium may lead to perforation of the nasal septum with an increased risk of respiratory cancer [2].
The removal of
chromium decreased [as] compared to that obtained from [the] single component Cr(VI) solution," said Dr Hussain.
A review of randomized controlled trials, published in the August issue of Diabetes Care, found that
chromium supplements produced modest improvements in blood sugar and cholesterol in some people with type 2 diabetes but had no effect in non-diabetic patients.
The review analyzed 15 clinical studies of people with diabetes; all showed that
chromium picolinate produced benefits in at least one measure of diabetes management without reports of adverse events.
The most significant health risks result from exposure to hexavalent
chromium particles by inhalation and through skin contact.
In 2003, Nutrition 21, the company that holds a patent on the use of
chromium picolinate to lower blood sugar, petitioned the Food and Drug Administration to approve eight health claims.
Trivalent
Chromium (CrIII)--a naturally occurring element used industrially for brick linings in high temperature furnaces and to make metals, metal alloys and chemical compounds.
Tests of the 10-nm alloy as a coating for steel have shown it to be as hard as
chromium and more resistant to marine corrosion, Schuh says.
The Glendale City Council has chosen to limit
chromium levels to 5 ppb and below - similar to caps adopted by Burbank and Los Angeles - and has so far kept residential drinking water well within state health limits by blending
chromium-tainted groundwater with more expensive water piped in from other parts of California.
The presence of chlorine ions in the water combined with the deflection of the mold brings about a chemical reaction between the chlorine and
chromium in the steel.
