DOWNLOAD EBOOKAssisted Phytoremediaion covers a wide range of uses of plants for remediation of environmental pollutants. It includes coverage of such techniques as root engineering, transgenic plants, increasing the biomass, use of genetic engineering and genome editing technology for rapid phytoremediation of pollutants. In order to improve the efficiency of plant remediation, genetic engineering plays a vital role in the overexpression of genes or gene clusters, which are responsible for degradation and uptake of pollutants. The book presents state-of-the-art techniques of assisted phytoremediation to better manage soil and water pollution in large amounts. This book is a valuable resource for researchers, students, and engineers in environmental science and bioengineering, with case studies and state-of-the-art research from eminent global scientists. This book serves as an excellent basis from which scientific knowledge can grow and widen in the field of environmental remediation. Provides a clear picture of how to design, tune, and implement assisted phytoremediation techniques Offers a comprehensive analysis of current perspective and state-of-the-art applications of assisted phytoremediation Introduces the potential of genetic engineering as a rapid, cost-effective technology for environmental remediation using plants

DOWNLOAD EBOOKLeonardite is a naturally occurring oxidized form of lignite coal that is rich in humic materials. It is collected during coal-mining procedures, as it is commonly found overlying coal seams. Humic substances have been shown to significantly enhance the aqueous solubilities of PAHs by acting as a surfactant, increasing the water solubility of the PAH and allowing the contaminants to enter the aqueous phase. The use of humic acids on contaminated soils has the potential to greatly enhance the solubility, and consequently the bioavailability, of PAHs allowing for an easier and more efficient bioremediation procedure. A fluorescence quenching method was used to determine the association constants (Kb) for various water-soluble humic materials and naphthalene. The objective of the microcosm study was to determine if a variety of dissolved humic material solution amendments could influence the biodegradation rate of selected PAHs, namely anthracene and benzo[a]pyrene, in a soil with previous exposure to PAHs.

DOWNLOAD EBOOKThis book describes the sources of water contamination by PAHs and their transportation and fate in natural aquatic systems. It then discusses, from the analytical chemist’s view, how to determine the presence of PAHs in water and wastewater, and the changes in PAH concentration during treatment processes. The text examines the removal of PAHs using membrane bioreactors and advanced sludge processes, highlighting results from both demonstration and full-scale plants. It also examines the presence of PAHs in conventional wastewater treatment plants, especially in sludge.

DOWNLOAD EBOOKThe increasing human population and the associated activities have negatively influenced the ecosystems and life on earth. The continuous addition of agrochemicals, heavy metals and industrial wastes/ effluents in the ecosystems have caused great harm, including loss of productivity, biodiversity, climate change and diseases in plants, animals and humans, resulting in increased marginal lands and endangered sustainability of life on earth. Hence, there is an urgent need to reverse the impact of dangerous pollutants through a holistic, sustainable and biotic approach. Bioremediation involves the utilization of biological systems, mainly plants (phytoremediation) or microorganisms or both in combination (rhizoremediation) for the removal or degradation of pollutants and revive the habitats in an eco-friendly manner. Recently, there have been many success stories related to bioremediation involving plants or plant-microbe interactions. These success stories are related to the removal of heavy metals, pesticides, polyaromatic hydrocarbons, explosives, radionuclides or reduction of biological oxygen demand, total dissolved solids, total suspended solids, oil spills in water bodies. Rhizoremediation has also been successfully used for reclamation of saline or marginal soils. With the range of pollutants and the total area (on earth) covered by these toxic chemicals, it is important that these eco-friendly technologies be utilized in a better way. The book throws light on the recent happenings, research and success stories related to bioremediation of polluted habitats through phytoremediation or rhizoremediation. The book also highlights some of the significantly important plant and microbial species involved in remediation, the physiology, biochemistry and the mechanisms of remediation by various plants and microbes, and suggestions for future improvement of bioremediation technology.
