UltraCat Catalytic Filter Systems For Chrome / Hexavalent Chrome
Hexavalent chromium, Chromium VI, is one of the valence states (+6) of the element chromium. It is usually produced by an industrial process. Chromium (VI) is known to cause cancer. In addition, it targets the respiratory system, kidneys, liver, skin and eyes.
Chromium Compounds Hazard Summary /EPA
Chromium occurs in the environment primarily in two valence states, trivalent chromium (Cr III) and hexavalent chromium (Cr VI). Exposure may occur from natural or industrial sources of chromium. Chromium III is much less toxic than chromium (VI). The respiratory tract is also the major target organ for chromium (III) toxicity, similar to chromium (VI). Chromium (III) is an essential element in humans. The body can detoxify some amount of chromium (VI) to chromium (III).
The respiratory tract is the major target organ for chromium (VI) toxicity, for acute (short-term) and chronic (long-term) inhalation exposures. Shortness of breath, coughing, and wheezing were reported from a case of acute exposure to chromium (VI), while perforations and ulcerations of the septum, bronchitis, decreased pulmonary function, pneumonia, and other respiratory effects have been noted from chronic exposure.
Human studies have clearly established that inhaled chromium (VI) is a human carcinogen, resulting in an increased risk of lung cancer. Animal studies have shown chromium (VI) to cause lung tumors via inhalation exposure.
Tri-Mer offers a wet Chrome Scrubber that has been used for trivalent chrome (Chrome III) for many decades. The Tri-Mer UltraCat ceramic filter system, a completely dry system, has also been proven to remove both chrome compounds in airborne applications with significant efficiency, warranting large-scale industrial installations. This involves special configuration of the system. Please reference Particulate Matter control (PM Control.)
