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

Metal toxicity and deficiency are both common abiotic problems faced by plants. While metal contamination around the world is a critical issue, the bioavailability of some essential metals like zinc (Zn) and selenium (Se) can be seriously low in other locations. The list of metals spread in high concentrations in soil, water and air includes several toxic as well as essential elements, such as arsenic (As), cadmium (Cd), chromium (Cr), aluminum (Al), and selenium (Se). The problems for some metals are geographically confined, while for others, they are widespread. For instance, arsenic is an important toxic metalloid whose contamination in Southeast Asia and other parts of world is well documented. Its threats to human health via food consumption have generated immense interest in understanding plants’ responses to arsenic stress. Metals constitute crucial components of key enzymes and proteins in plants. They are important for the proper growth and development of plants. In turn, plants serve as sources of essential elements for humans and animals. Studies of their physiological effects on plants metabolism have led to the identification of crucial genes and proteins controlling metal uptake and transport, as well as the sensing and signaling of metal stresses. Plant-Metal Interactions sheds light on the latest development and research in analytical biology with respect to plant physiology. More importantly, it showcases the positive and negative impacts of metals on crop plants growth and productivity.

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.

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 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.

Analysis of 7 native species (5 vascular plant species-Carex aquatilis, Carex canescens, Carex utriculata, Equisetum arvense, Juncus ensifolius-- and 2 bryophytes--Pohlia nutans and Polytrichum commune) showed variable metal (Al, As, Cd, Cu, Fe, Pb and Zn) levels by species, in both roots and shoots. The mine wetland plants had higher metal concentrations than the reference wetland plants, although this varies by plant species, tissue and metal. Organic matter had high element concentrations and represents a large reservoir of metals in the mine wetland. Survival of Carex utriculata plants grown from onsite seed compared to plants grown from offsite seed was not different in the first year following remediation. Plants growing in the remediated sites showed no difference or significantly higher metal concentrations of Al (shoots), Cd, Cu, Fe, Pb and Zn in Carex utriculata and Carex aquatilis tissues as compared to the unremediated mine wetland. Ontario mine remediation efforts showed variable results but plant available metal increased following remediation for all metals analyzed and not the metalloid As.
