About the Book
Some 65 of the known 92 elements are metallic in nature. The term ‘metal’ designates an element that is a good conductor of electricity whose electrical resistance is directly proportion to absolute 0T. In addition, metals share some distinctive characteristics such as high thermal conductivity and high density. Metallic elements are intrinsic components of the environment. Some 19 heavy metals of the known 65 metals are toxic in nature and cause a great threat to the living as well as non-living world, and so man is no exception. Actually toxic heavy metals are present at <0.1% levels in the earth’s crust but anthropogenic activities such as smelting and mining of ores, releasing industrial wastes, use of metallic compounds in industries and in the production of vehicles and aeroplanes have released a large number of toxic metals and their salts into th environment. So, dispersion of heavy metals in environment has become a most challenging problem. If proper management and mass awakening right from grass root level to top policy makers have not been considered inevitable within time, no force on this earth can check the propagation of carcinogenic characters of the heavy metals. This book will be helpful in solving the crux of heavy metal pollution; as it is compilation of most advanced research articles of the scientists of repute in the concerned field. Besides, the book will be very much helpful for the students, research scholars, professors, scientists as well as for those who have interest in toxicology.
