Download or read book Effect of Heavy Metal Pollution on Plants written by N. W. Lepp and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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
Download or read book Plant ABC Transporters written by Markus Geisler and published by Springer. This book was released on 2014-09-06 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the fascinating superfamily of plant ATP-binding cassette (ABC) transporters and their variety of transported substrates. It highlights their exciting biological functions, covering aspects ranging from cellular detoxification, through development, to symbiosis and defense. Moreover, it also includes a number of chapters that center on ABC transporters from non-Arabidopsis species. ABC proteins are ubiquitous, membrane-intrinsic transporters that catalyze the primary (ATP-dependent) movement of their substrates through biological membranes. Initially identified as an essential aspect of a vacuolar detoxification process, genetic work in the last decade has revealed an unexpectedly diverse variety of ABC transporter substrates, which include not only xenobiotic conjugates, but also heavy metals, lipids, terpenoids, lignols, alkaloids and organic acids. The discovery that members of the ABCB and ABCG family are involved in the movement of phytohormones has further sparked their exploration and provided a new understanding of the whole family. Accordingly, the trafficking, regulation and structure-function of ABCB-type auxin transporters are especially emphasized in this book.
Download or read book Heavy Metal Remediation written by Dhamendra Kumar Gupta and published by Nova Science Pub Incorporated. This book was released on 2014-01-01 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants have a very specific and efficient mechanism to obtain, translocate and store nutrients from the surrounding environment. The precise mechanism that helps a plant in nutrient translocation from root to shoot also, in the same way, transfers and stores toxic metals within their structure. Metal toxicity generally causes multiple direct or indirect effects on plants, affecting nearly all of their physiological functions. Plant tolerance to heavy metals depends largely on plant efficiency in uptake, translocation and sequestration of heavy metals in specific cell organelles or specialized tissues. The main purpose of this book is to present a holistic view of the recent advancement in the field of accumulation and remediation using plants, the green solar powered alternative to ameliorate heavy metal from the polluted environment. The key features of the book are related to metal transporters and metal accumulation mechanisms under heavy metal stress in plants, plant transcriptional regulation and responses under metal contamination, multiple toxic metal contaminations and its phytoremediation approaches etc. Based on the advancement of research in recent years, the information compiled in this book will bring an in-depth knowledge on the bioaccumulation of metals, their transportation in natural conditions or genetically modified plants and their strategy to cope with the toxicity to survive in the hostile environment.

This book was released on 2005-03-03 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excessive levels of heavy metals can be introduced into the environment, for example, by industrial waste or fertilizers. Soil represents a major sink for heavy metals ions, which can then enter the food chain via plants or leaching into groundwater. In Heavy Metal Ions in the Environment, the author looks at where heavy metals ions come from, how they interact with the environment and how they can be removed from the environment – by a process known as remediation. This book serves as a valuable addition to an increasingly important field of study, which is, at present, served by a limited number of archival texts. - Includes comprehensive coverage of heavy metal ions in the environment - Is practical and easy to read - Is suitable for students and researchers in environmental science and environmental or chemical engineering
Download or read book Metal Toxicity in Higher Plants written by Marco Landi and published by . This book was released on 2020-01-08 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metals are important environmental pollutants and their toxicity is a problem of increasing significance for ecological, nutritional, and environmental reasons. These pollutants, ultimately derived from a growing number of diverse anthropogenic sources (industrial effluents and wastes, urban runoff, sewage treatment plants, boating activities, agricultural fungicide runoff, domestic garbage dumps, and mining operations), have progressively affected more and more different ecosystems. Even agricultural lands are progressively becoming enriched of metals due to long-term use of phosphatic fertilizers, sewage sludge application, dust from smelters, industrial waste and bad watering practices in agricultural lands.Among these metals, Cu, Fe, Mn, Mo and Zn are pivotal micronutrients, while Ag, As, Cd, Cr, Hg, Pb, Sb and V and are non-essential for plants and have no known function as nutrients and seem to be more or less toxic to all plants and microorganisms. Sodium excess deserves particular attention. Several agricultural lands are indeed becoming familiar with the problem of salinization, due to the use of fresh water which contains a high level of NaCl or due to intensive fertilization, especially in arid and semi-arid environments characterized by poor rainfalls. Overall, the presence of both essential and non-essential metals in the atmosphere, soil and water, in excessive amounts, can cause serious problems to all organisms. Knowledge of plant-metal interactions is important for the safety of the environment, but also for reducing the risks associated with the introduction of trace metals into the food chain. Although intense research has been conducted during the last 30 years, many aspects remain to be clarified concerning the effect of metals in higher plants.Our goal for this book is to critically review existing literature related to the specific effects of different metals in plants, as well as to provide new evidence about plant-metal interactions in order to clarify mechanisms of metal uptake, translocation, and partitioning and the effect of metal toxicity. Consequences related to accumulation of metals in food products have been described. Physiological and biochemical mechanisms adopted by plants to cope with metal excess and possible implications for phytoremediation of metal-contaminated soils are also discussed. Therefore, we believe that this book will provide a comprehensive overview regarding some aspects of metal toxicity in plants and it will be useful for scientist working in this field of research, but it will also be of practical interest to environmentalists, policy-makers, and resource managers working on the topic. We wish to thank all the authors who joined this book project by contributing their valuable work. Lastly, we extend our sincere thanks to Nova Science Publishers for their efficient support.
Download or read book Cellular and Molecular Phytotoxicity of Heavy Metals written by Mohammad Faisal and published by Springer Nature. This book was released on 2020-10-19 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant growth and development is closely dependent on the plant environment, including the wide-spread presence of organic and inorganic xenobiotics and pollutants. Currently, heavy metals are the most common inorganic environmental pollutants and they have pronounced effects and consequences not only for plants, but also for the ecosystem in which the plants form an integral component. It has been suggested that these contaminants accumulate in agricultural crops, thus entering the food chain and posing a significant health risk. Plants growing in polluted sites exhibit altered metabolism, reduced growth, and decreased biomass production. These pollutants adhere to plant roots and exert physical or chemical toxicity and subsequently cell death in plants. Yet, plants have developed various defence mechanisms to counteract the toxicity induced by heavy metals. Only detailed study of the processes and mechanisms would allow researchers and students to understand the interactions, responses, and adaptations of plants to these pollutants; however, there are several unresolved issues and challenges regarding the interaction and biological effects of heavy metals. Therefore, this volume provides relevant, state-of-the-art findings on environmental phytotoxicity and the mechanisms of such interactions at the cellular and molecular levels. This volume consists of chapters on relevant topics contributed by different experts or group of experts so as to make available a comprehensive treatise designed to provide an in-depth analysis of heavy metals phytotoxicity. This book may serve as a reference to scientists, researchers and students in the fields of toxicology, environmental toxicology, phytotoxicology, plant biology, plant physiology, plant biochemistry and plant molecular biology, and especially those interested in heavy metals toxicology.
