Plant Adaptation And Phytoremediation

The problems engendered by the conflicting imperatives of development and ecology show no sign of ending, and every day more locations are added to the list of landscapes poisoned by human activity. This vital book, featuring an international set of authors, is a key reference for researchers and environmental managers, as well as anyone involved in the mining industry or landscape remediation. The comprehensive coverage of current approaches to phytoremediation begins by examining the problem. It looks at natural and human-induced toxins, and their effects on natural vegetation as well as agricultural crops. Particular attention is paid to the two largest challenges to remediation – heavy metals, and the salt stress that is impeding agricultural productivity worldwide. The text moves on to focus on the efficacy of different plant species in removing toxic pollutants from the environment. Along with analysis of a number of case studies, this section includes new and updated information on the mechanism of toxin-tolerance in plants.

Adaptive Phytoremediation Practices: Resilience to Climate Change discusses current phytoremediation practices under an ever-pressing need for environmental remediation due to increasing pollution in a changing climate. Phytoremediation is increasingly relevant due to plants’ high effectiveness and sustainability during remediation and the ability of potential phytoremediation plants to adapt to changes in climate. Changing climatic conditions cause various biotic and abiotic stresses in plants and thereby negatively affect a plant’s establishment, growth, and yield. Therefore, the integration of suitable climate-resilient plants and adaptive remedial practices along with proper agro-biotechnological interventions is of paramount importance to mitigate the rapidly growing pollution. This book is an important reference for environmental scientists, particularly those working in pollution management and remediation, forming an up-to-date collection of phytoremediation practices that provide sustainable solutions as a holistic approach for carrying out phytoremediation under changing climatic conditions. Provides up-to-date research and understanding on how to design, refine, and implement adaptive phytoremediation practices Focuses on enhancing resilience in plants toward climate change and explanations of the characteristics of resilient plants for adaptive phytoremediation practices in a changing climate Presents methods and solutions for adapting phytoremediation practices to climate change

This book addresses the crucial aspects of plant adaptation strategies in higher as well as lower plant groups. Stress induced by changing environmental conditions disrupts or alter various physiological and metabolic processes in organisms, however, plants have evolved various defence strategies to cope with external perturbations. The book discusses speciation changes in response to extreme ecological conditions such as cold, heat, aridity, salinity, altitude, incidental UV radiation and high light intensity, which are particularly relevant in the current scenario of global warming. It also explores the effects of human activities and emission of phytotoxic gases. Further, it describes the overall adaptation strategies and the multifaceted mechanisms involved (integrated complex mechanism), ranging from morphological to molecular alterations, focusing on plants’ capabilities to create an inner environment to survive the altered or extreme conditions. This book is a valuable tool for graduate and research students, as well as for anyone working on or interested in adaptation strategies in plants.

The soil is being contaminated continuously by a large number of pollutants. Among them, heavy metals are an exclusive group of toxicants because they are stable and difficult to disseminate into non-toxic forms. The ever-increasing concentrations of such pollutants in the soil are considered serious threats toward everyone’s health and the environment. Many techniques are used to clean, eliminate, obliterate or sequester these hazardous pollutants from the soil. However, these techniques can be costly, labor intensive, and often disquieting. Phytoremediation is a simple, cost effective, environmental friendly and fast-emerging new technology for eliminating toxic heavy metals and other related soil pollutants. Soil Remediation and Plants provides a common platform for biologists, agricultural engineers, environmental scientists, and chemists, working with a common aim of finding sustainable solutions to various environmental issues. The book provides an overview of ecosystem approaches and phytotechnologies and their cumulative significance in relation to solving various environmental problems. Identifies the molecular mechanisms through which plants are able to remediate pollutants from the soil Examines the challenges and possibilities towards the various phytoremediation candidates Includes the latest research and ongoing progress in phytoremediation

Phytoremediation: Biotechnological Strategies for Promoting Invigorating Environs focuses on phytoremediation’s history, present and future potential, discussing mechanisms of remediation, different types of pollutant and polluted environs, cell signaling, biotechnology, and molecular biology, including site-directed DNA and the omics related to plant sciences. Sections focus on phytoremediation as an economically feasible and environmentally safe strategy, including its mechanisms from macroscopic to microscopic level, strategies of assisted phytoremediation, the role of omics on innovations on the field, the development of genetically modified plants (GMPs) to deal with pollutants, the future prospects of targeted genetic engineering in phytoremediation and remediation advantages and disadvantages. Other sections in the book explore the phytoremediation of specific environs (water and soil) and specific contaminants that are of major worldwide concern. Presents phytoremediation mechanisms at a microscopic level (molecular mechanisms) Covers remediation in different environs and in different kinds of pollutants Conveys the economic aspects relating to phytoremediation

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

Phytoremediation Potential of Perennial Grasses provides readers with the knowledge to select specific perennial grass species according to site-specific needs. In addition, it demonstrates the potential opportunities for grass-based phytoremediation to yield phytoproducts, especially biomass-based bioenergy and aromatic essential oils as a green economy while in the process of remediating contaminated sites. The book brings together recent and established knowledge on different aspects of grass-based phytoremediation, providing this information in a single source that offers a cutting-edge synthesis of scientific and experiential knowledge on polluted site restoration that is useful for both practitioners and scientists in environmental science and ecology. Provides a holistic approach to grass-based phytoremediation, covering the ecological, economic and social issues related to its management Addresses the key role that grass-based phytoremediation plays in maintaining ecosystem services in polluted sites Includes strategies to mitigate costs related to the phytoremediation of polluted sites
