CHROMIUM (III) AND CHROMIUM (VI) IN RELATION TO HUMAN PHYSIOLOGY: A REVIEWPANKAJ VERMA, SHARAD CHANDRA SRIVASTAVA AND MADHU TRIPATHIAbstract Chromium is an essential element for human body. It is the present naturally in onions, tomatoes, oysters, whole grains, bran cereals, and potatoes. It controls level of sugar in human body by interacting with insulin. The most common form of chromium is chromium (III) and chromium (VI). When level of chromium exceeds than the permissible or acceptable limit, then it creates adverse effect on human physiology. Out of most common states, chromium (VI) is highly toxic than chromium (III). Now chromium is widely used in leather industry as a tanning agent. During the tanning process some part of chromium salts discharged as such in aquatic environment that create various health hazards in human beings. To overcome the problem of chromium toxicity, various techniques are used but advance processes like bioremediation, nanotechnology, absorption, and adsorption are very useful in reduction of toxic level of chromium.
