Determination Of Trace Metals In Various Environmental Samples.

      Аннотация: The role of metals in the metabolism, maintenance of biological system, steel preparation and pharmaceutical preparation has been recognized for many decades. Pollution due to toxic metals is considered to be of immense importance due to the non-biodegradable nature and long biological half lives.Exposure to very low concentrations of metals like Pb, Se, Cu, Co, Zn, Ni and Cd may produce adverse effects on health and behavior of population. Although metals such as copper, nickel, selenium, cobalt, chromium, cadmium and zinc are essential for human beings, chronic metabolic disturbances may result from excess or deficiency of these metals.Therefore, the knowledge on the role of metals and their presence in biological systems has been the principal target of many a research study in the past and is still continuing. Hence, the continuous research on the study of metals of biological samples, pharmaceutical preparation and steel preparation is conducted to fulfill the lacunae if any, existing in the earlier studies. Hence the author has taken up research in this field and selected the topic “Determination of trace metals(Se, Cr, Co, Cu, Ni, Cd and Zn) in various environmental samples"
