Since Vauquelin's first production of metallic chromium, small amounts of native (free) chromium metal have been discovered in rare minerals, but these are not used commercially.
Arica and Bayramoglu (2005) also showed the utilization of native, heat and acid-treated microalgae Chlamydomonas reinhardtii for biosorption of chromium (VI) ions.
Travelling expositions of "natives" existed even earlier.
The carcinogenic plume of hexavalent chromium, meanwhile, which was discovered 10 years ago, is migrating towards nearby Native lands and the regional aquifer.
But the keyword is "perfectly" — as Google notes, "It's important to us that the Mac port of Chromium feels and performs like a native Mac application, and that it provides the kind of high-quality experience Mac users expect".
The MKT's leather is made using an organic tanning method, free of harsh chromium additives.
Sensitive and accurate measurement of blood chromium is very important to assess the chromium nutritional status.
Both sensors exhibit high selectivity to hexavalent chromium even in presence of trivalent chromium.
Metals included small amounts of lead, chromium, zinc and cadmium.
The most prominent example of toxic chromium is hexavalent chromium (Cr VI)).
