Metals and Metalloids in Soil-Plant-Water Systems: Phytophysiology and Remediation Techniques examines the impact of metal/metalloid contamination on the plant lifecycle, along with microbes present in soil. Highlighting uptake and translocation, the book also examines antioxidant, photosynthesis and growth characteristics of plants grown in metal contaminated soil. Beginning with an introduction to different sources of soil and water pollution, chapters assess the environmental cytotoxicity pollution impact on plants, as well as how the generation of reactive oxygen and nitrogen species in plant tissues is affected. The book also discusses various soil remediation methodologies, including the potential applications of metal oxidizing microbes and nanomaterials. This is an essential resource for researchers and students interested in plant physiology, soil science, environmental science and agriculture. Provides a comprehensive overview of metal and metalloids speciation, fractionation, bioavailability and transfer to plants Analyzes properties of plants grown with excess metals/metalloids in soils Highlights applications of biochar and other biostimulants for sustainable metal/metalloid remediation

This third edition of the book has been completely re-written, providing a wider scope and enhanced coverage. It covers the general principles of the natural occurrence, pollution sources, chemical analysis, soil chemical behaviour and soil-plant-animal relationships of heavy metals and metalloids, followed by a detailed coverage of 21 individual elements, including: antimony, arsenic, barium, cadmium, chromium, cobalt, copper, gold, lead, manganese, mercury, molybdenum, nickel, selenium, silver, thallium, tin, tungsten, uranium, vanadium and zinc. The book is highly relevant for those involved in environmental science, soil science, geochemistry, agronomy, environmental health, and environmental engineering, including specialists responsible for the management and clean-up of contaminated land.

Understanding metalloids and the potential impact they can have upon crop success or failure Metalloids have a complex relationship with plant life. Exhibiting a combination of metal and non-metal characteristics, this small group of elements – which includes boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), and tellurium (Te) – may hinder or enhance the growth and survival of crops. The causes underlying the effects that different metalloids may have upon certain plants range from genetic variance to anatomical factors, the complexities of which can pose a challenge to botanists and agriculturalists of all backgrounds. With Metalloids in Plants, a group of leading plant scientists present a complete guide to the beneficial and adverse impacts of metalloids at morphological, anatomical, biochemical, and molecular levels. Insightful analysis of data on genetic regulation helps to inform the optimization of farming, indicating how one may boost the uptake of beneficial metalloids and reduce the influence of toxic ones. Contained within this essential new text, there are: Expert analyses of the role of metalloids in plants, covering their benefits as well as their adverse effects Explanations of the physiological, biochemical, and genetic factors at play in plant uptake of metalloids Outlines of the breeding and genetic engineering techniques involved in the generation of resistant crops Written for students and professionals in the fields of agriculture, botany, molecular biology, and biotechnology, Metalloids in Plants is an invaluable overview of the relationship between crops and these unusual elements.

Plant Metal Interaction: Emerging Remediation Techniques covers different heavy metals and their effect on soils and plants, along with the remediation techniques currently available. As cultivable land is declining day-by-day as a result of increased metals in our soil and water, there is an urgent need to remediate these effects. This multi-contributed book is divided into four sections covering the whole of plant metal interactions, including heavy metals, approaches to alleviate heavy metal stress, microbial approaches to remove heavy metals, and phytoremediation. - Provides an overview of the effect of different heavy metals on growth, biochemical reactions, and physiology of various plants - Serves as a reference guide for available techniques, challenges, and possible solutions in heavy metal remediation - Covers sustainable technologies in uptake and removal of heavy metals

While not all metals in Soil--plant systems are inherently toxic, particularly in low concentrations, there is an increasing incidence of metal pollution from aerial fallout, spoils, wastes and agricultural amendments including sewage sludge. Toxic Metals in Soil--Plant Systems discusses the processes of trace-metal cycling in contaminated ecosystems under conditions where their concentrations become toxic through high loading rates, long-term exposure or altered environmental conditions. Other environmental and pedological concentration mechanisms are discussed, including cation exchange and anion adsorption onto different soil materials. The book is divided into two sections; the first part discusses the sources and fates of metals in ecosystems, with an up-to-date review of the processes which control metal speciation in soils, metal uptake mechanisms, and plant responses to toxic metal concentrations in soils. A clear understanding of these processes and their interactions in soil is necessary before it is possible to instigate amelioration and restoration programmes for metal-contaminated land. In the second part of the book, a selection of case studies are presented which discuss metal toxicities and metal cycling in a range of different ecosystems, including managed agricultural systems, deciduous woodland, upland heather moorland, and tropical wetlands. In these studies a number of current issues are addressed, including the setting of toxicity thresholds for safe sewage sludge application to agricultural land, the accumulation of soil metals over time in aerially impacted systems, and metal transfers between ecosystem compartments, which are of particular concern in food crops. Providing an integrated view of toxic metals both in the soil and associated growing plants, this book covers a wide range of topics including agriculture, soil science, ecology and forestry and will be of use to researchers and environmental consultants working in these fields.

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.

Written by a multidisciplinary group of soil and environmental scientists, Biophysico-Chemical Processes of Heavy Metals and Metalloids in Soil Environments provides the scientific community with a critical qualitative and quantitative review of the fundamentals of the processes of pollutants in soil environments. The book covers pollutants' speciation, mobility, bioavailability and toxicity, and impacts on development of innovative restoration strategies. In addition, the development of innovative remediation strategies for polluted soils is covered.

Report, the editors replaced the term "speciation" wherever it occurred by "identification and quantification," or "description of abundance," or "reactivity," or "transformation" of a chemical species, according to whichever one of the four meanings the author had evidently meant to convey. In line with the Dahlem Workshop Model, this Report comprises the background papers written in advance of the meeting on the current status of problems in environmental research and on advanced analytical tech niques for the identification and quantification of chemical species, as well as the group reports summarizing the results of the discussions held during the meeting. Each group report was prepared during the meeting by one "rapporteur" with the help of members of that group and finalized by the rapporteur (listed as the first author of the group report) after the meeting, taking into account both verbal comments made during the presentation of the reports in the plenary session at the end of the workshop and written comments received afterwards.
