About the book
From time immemorial, heavy metals have proved to be a source of concern for the environment, namely Zn,Hg and U and Cr to name a few. It is the persistent efforts of scientists across the globe to get rid of harmful effects of these heavy metals. Since Cr is one of the essential elements in human body functions, it is necessary to study their role and also their toxicity in a particular oxidation state. Be it the aquatic environment like the sea, the biological systems like the soil, plants and atmosphere in general, Cr toxicity plays an important role in studying variations of heavy metal toxicity. Chromium is an important mineral for obese people, and it is one of the key minerals in controlling blood sugar and lipid levels. As the main ingredient of glucose tolerance factor (GFT), chromium helps insulin in reducing the blood glucose, by stimulating glucose uptake from the muscles and other tissues. When the Chromium levels are lower, the circulating level of (GFT) is lower, and as a result, insulin is less effective in reducing blood sugar. Hence, blood sugar remains high, stimulating further insulin release, which is again blocked from being effective. Researchers have been putting efforts in this kind of environmental study and it has shown very encouraging results. It is my sincere effort to bring together the researchers in this field of science which is the recent trend in keeping our health, environment safe and clean, devoid of heavy metals that can play havoc in our daily lives if care is not taken to a microscopic level. The role of Cr in body functions and also in the environment will be elucidated in this book.
