Enhancing Secure Service Authentication Protocol For Vanets

Abstract :

Heavy metal contaminations are becoming growing common issues in developing countries like India and elsewhere. Rapid urbanization, industrialization and excessive population growth are the most leading causes of environmental degradation. Heavy metals such as Pb, Zn, Cd and As etc., are the major toxic pollutants which show harmful effects on living system. Lead is one of such contaminants, which disrupts the food chain and it is poisonous even at very low concentration. The existing purification technologies used for removal of contaminants from wastewater are not only expensive but causes harmful impact on ecosystem subsequently. Bioremediation is an ecofriendly technique which is both ecologically sound and economically feasible. It is an attractive and alternative choice to the existing cleanup methods and is less expensive. Here different parts of Amla tree are used as Bio adsorbent such as stem, external bark, rachis and leaves were taken in the form of charcoal to remove, detoxify or immobilize heavy metals. Removal concentration of lead was analyzed by using Atomic Absorption Spectrophotometer (AAS). The objectiveof this study is to evaluate the current condition of Bioremediation as an innovative technique and to discuss its usefulness and prospective in the remediation of lead tainted water.
