Metals And Metalloids Are Ubiquitous Environmental Constituents And Cannot Be Broken Down To Non-Toxic Forms By The Biological System. Once The Ecosystem Is Contaminated With Them, They Remain As A Potential Hazard To Human Health For Many Years. Heavy Metals Are Particularly Important In This Respect. This Book, Which Is A Part Of Man And Environment Series, Discusses Diverse Issues Relating To Heavy Metals And Environmental And Human Health Problems.
Therefore, it is inevitable to keep away from being exposed to heavy metals.
Emissions into the air constitute the greatest source of heavy-metal pollution.
They also contaminate aquatic ecosystems and soils through atmospheric fallout.
This book has up-to-date literature and research findings on the heavy metals such as, mercury, cobalt, cadmium, managnese, copper, chromium, boron, iron, lead, nickel, selenium, vanadium, zinc, arsenic, silver, gold, etc. The author have discussed their histopathological, biochemical, histochemical and enzymological effects in plants and animals, particularly in liver, kidney, heart, muscles, brain, bones, reproductive organs, intestine, endocrine system, etc.

The term "Heavy Metal" is somewhat imprecise, but includes most metals with an atomic number greater than twenty, but excludes alkali metals alkaline earths, lanthanum andactinides. Human civilization started with the accidental discovery of - especially Copper. Since then living organisms have taken long strides with the help of metals.

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
Some 65 of the known 92 elements are metallic in nature.
