This title focuses on the many aspects of the interaction between plants and heavy metals. Not only it describes the effects of heavy metal toxicity on the plant cell and its organs but it also examines the mechanisms that plants adopt to scavenge heavy metals at cellular, physiological, and metabolic level. Plants and Heavy Metals also analyses Hyperaccumulator plants and shows their potential role in phytoremediation technologies in light of the recent research results.

Heavy metal phytotoxicity has been known for more than a century. However, research in the past years has confirmed the immense damage by metal pollution to plants, the soil and ultimately to humans. By reviewing both field and laboratory work, this book deals with the various functional and ecological aspects of heavy metal stress on plants and outlines the scope for future research and the possibilities for remediation.

This book focuses on the menace of metal pollution and its impact on plants, particularly food grains, pulse and vegetable plants covering morphological, anatomical, physiological and biochemical aspects. It includes comparative studies among metal hyper-accumulators (metallophytes) and non-accumulators including exogenous hormonal alleviation in them due to metal stress. Low dose stimulation effects are also reviewed. The most significant feature of the book is its extensive coverage of genomics, metabolomics, ionomics, proteomics and transcriptomics in metal non-hyper-accumulators and hyper-accumulators. Being an edited volume, the book incorporates a variety of research perspectives, enhancing the existing knowledge about metal pollution and points to newer avenues to be researched.

Trace metals occur as natural constituents of the earth's crust, and are ever present constituents of soils, natural waters and living matter. The biological significance of this disparate assemblage of elements has gradually been uncovered during the twentieth century; the resultant picture is one of ever-increasing complexity. Several of these elements have been demonstrated to be essential to the functions of living organisms, others appear to only interact with living matter in a toxic manner, whilst an ever-decreasing number do not fall conveniently into either category. When the interactions between trace metals and plants are considered, one must take full account of the known chemical properties of each element. Consideration must be given to differences in chemical reactivity, solubility and to interactions with other inorganic and organic molecules. A clear understanding of the basic chemical properties of an element of interest is an essential pre-requisite to any subsequent consideration of its biological significance. Due consideration to basic chemical considerations is a theme which runs through the collection of chapters in both volumes.

An in-depth look at the most promising technology for metal remediation. With current cleanup methodologies offering no real solution to the serious environmental implications of toxic metal contamination, there is a growing need among remediation professionals for effective, affordable, nonpolluting alternatives to energy-intensive engineering processes. This book presents one such promising alternative-the extraordinary new technology of phytoremediation. Through first-rate contributions from the top scientists in the field, Phytoremediation of Toxic Metals surveys worldwide pioneering efforts in the use of plants to treat contamination of such metals as lead, cadmium, chromium, and even radionuclides. The authors explore all major aspects of the technology-how it utilizes the metal-accumulating properties of selected or engineered plants to remove toxic metals from soils and water, how to transfer knowledge from the laboratory to the field, and what methods are most viable for commercial application. Complete, state-of-the-art coverage includes: * The economic advantages of plant-based technology * Regulatory considerations for future phytoremediation * Phytoextraction, phytostabilization, and phytofiltration of toxic metals * Photostabilization of metals using hybrid poplar trees * Phytovolatilization for the special case of mercury and selenium * The biological mechanisms of metal-accumulating plants

of metal interactions with subcellular biochemical systems usually either are metabolites of the system affected (porphyrinurias) or represent some specific function of a cellular system being impaired (proteinurias). One typically finds a continuum of symptoms, from the subtle or so-called "no effect" bio chemical and physiological indicators of exposure to severe clinical disease and death. This continuum is the basis of much of the controversy since many health officials follow the traditional practice of applying the "threshold health-effect" concept in evaluating the problems of environmental exposure to metals. The past decade or so, however, has seen a vast increase in our understanding of the effects of elevated concentrations of toxic metals in local populations and ecosystems. At the same time, there is a growing awareness that the effects of the metals which occur naturally in the environment must be distinguished from those imposed by the pollutant fraction. This point was amply document ed in a recent study of cadmium intake and cadmium in a number of human tissues in Sweden, Japan, and the United States, which showed fairly conclu sively that the background exposure in Japan was about threefold higher than in the other two countries (2). One immediate implication is that any health ef fect studies of cadmium in Japan using control groups within that country are liable to underestimate the difference between the exposed and the control groups simply because of the the high "background" intake.

Heavy metal accumulation in soil and water from natural sources or anthropogenic activities have produced severe environmental contamination in some parts of the world due to the persistence of metals in the environment by their accumulation throughout the food chain. The purpose of this book is to present the most recent advances in this field, mainly concerning the uptake and translocation of heavy metals in plants, mechanisms of toxicity, perception of metal and regulation of cell response under metal stress. Another key feature of this book is related to the studies on signaling and remediation processes in recent years, which have taken advantage of recent technological advances including "omic" approaches. In recent years transcriptomic, proteomic and metabolomic studies have become very important tools for analyzing both the dynamics of changes in gene expression and the profiles of protein and metabolites under heavy metal stress. This information is also very useful for plotting the complex signaling and metabolic network induced by heavy metals, in which hormones and reactive oxygen species (ROS) also play an important role. Understanding the mechanism involved in sequestration and hyperaccumulation is very important to developing new strategies of phytoremediation, which are reviewed in several chapters of this book. The information included yields very stimulating insights into the mechanism involved in the regulation of plant responses to heavy metals, which in turn improve our knowledge of cell regulation under metal stress and the use of plants for phytoremediation.

Plants possess a range of potential cellular mechanisms that may be involved in the detoxification of heavy metals and thus tolerance to metal stress. Metal toxicity causes multiple direct and indirect effects in plants that concern practically all physiological functions. The main purpose of this book is to present comprehensive and concise information on recent advances in the field of metal transport and how genetic diversity affects heavy metal transport in plants. Other key futures of the book are related to metal toxicity and detoxification mechanisms, biochemical tools for HM remediation processes, molecular mechanisms for HM detoxification, how metallomics and metalloproteomics are affected by heavy metal stress in plants, and the role of ROS metabolism in the alleviation of heavy metals. Some chapters also focus on recent developments in the field of phytoremediation. Overall the book presents in-depth information and the most essential advances in the field of heavy metal toxicity in plants in recent years.
