Gold Nanoparticles exhibit intrinsic surface reactivity and high surface areas and can strongly chemisorb Mercury, Lead and Cadmium. The size, surface structure and interparticle interaction of nanomaterials determine their unique properties and the improved performances and make their potential application in many areas. Monitoring the levels of Hg , Pb, Cd along with Malathion and Chloropyrifos pesticides using Gold Nanoparticles is a continuous research and it is necessary to detect the concentration levels of Hg, Pb, Cd and Malathion, Chloropyrifos pesticide residues in various...

The growth of population along with new technological developments and unchecked industrialization, have upset the delicate balance of nature. In thickly populated cities like Tirupati, this problem has further aggravated by a high density of population, massive industrialization and consequent problems of urban planning. All these leads to "Environmental Degradation". "ENVIRONMENTAL DEGRADATION" means lowering of environmental quality at local, regional, and global scales by both Natural Processes and Human Activities. For example volcanic eruptions, earthquakes, submergence and emergence,...

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...
