This book sheds light on this global environmental issue and proposes solutions to reduce contamination through multi-disciplinary approaches. Water is considered a vital resource because it is necessary for all aspects of human and ecosystem survival. However, due to natural processes and anthropogenic activities, various pollutants have been added to the groundwater system. Among these, heavy metals are some of the most serious pollutants. Cd, a toxic heavy metal used in Ni-Cd batteries, the coloration of plastic and various discarded electronic products released into the water system causes serious health issues. The chronic exposure to Cd produces a wide variety of acute and chronic effects in humans.This edited book brings together a diverse group of researchers to address the challenges posed by global mass poisoning caused by cadmium contamination of water bodies. This book contains three sections. The first section describes the different sources and distribution of cadmium in water ecosystem. The second section explains the health risks linked to cadmium toxicity. The third section addresses sustainable cadmium toxicity mitigation strategies and the potential applications of recent biological technology in providing solutions.

This edited book brings together a diverse group of researchers to address the challenges posed by global mass poisoning caused by lead contamination of soil and plants. Lead is among the elements that have been most extensively used by man over time. This has led to extensive pollution of surface soils on the local scale, mainly associated with mining and smelting of the metal and addition of organic lead compounds to petrol. Release of lead to the atmosphere from various high-temperature processes has led to surface contamination on the regional and even global scale. Lead is particularly strongly bound to humic matter in organic-rich soil and to iron oxides in mineral soil and is rather immobile in the soil unless present at very high concentrations. In addition, plants grown on lead-rich soils incorporate lead and thus the concentration of lead in crop plants may be increased. Lead enters in the food chain through consumption of plant material. A high concentration of lead has been found to be harmful to vegetation. As the lead concentration increases, it adversely affects several biological parameters and eventually renders the soil barren. The book sheds light on this global environmental issue and proposes solutions to contamination through multi-disciplinary approaches.This book contains three sections. First section describes the different sources and distribution of lead in soil and plant ecosystems. Second section explains the health risks linked to lead toxicity. Third section addresses sustainable lead toxicity mitigation strategies using the potential applications of recent biological technology.This book is a valuable resource to students, academics, researchers, and environmental professionals doing field work on contamination throughout the world.

This book delivers an outline to graduate, undergraduate students, and researchers, as well as academicians who are working on lead toxicity with respect to remediation. It covers sources of lead contamination and its impact on human health and on prospective remediation through multi-disciplinary approaches with application of recent advanced biological technology.
