The success of phytoremediation technique is determined by the selection of efficient plant species suitable for the removal of the contaminants. Therefore, suitable plant species have been screened for their ability to withstand and degrade PAHs in contaminated soils. Hence in this study, the phytoremediation potential of 14 different plant species comprising nine plants with C3 photosynthetic pathway and five plants with C4photosynthetic pathway in remediation of B[a]P and pyrene contaminated soils was investigated. A green house experiment was conducted for 50 days to measure the changes in physiological, biochemical parameters, bioaccumulation and degradation ability of plants in soils spiked with 48 mg kg-1 and 194 mg kg-1 of B[a]P and PYR, respectively. The performances of C4 plants were observed to be better than C3 plants in terms of biochemical and physiological parameters.

Interest in phytoremediation as a solution for contaminants in groundwater and soil has exploded. The project documented in Phytoremediation of Hydrocarbon Contaminated Soils presents innovative technology for environmental clean up using in situ treatment. It describes the results of a field study focusing on hydrocarbon contamination, especially polynuclear aromatic hydrocarbons, in surface and near surface soils. The field demonstration used soils contaminated with aged diesel fuels. The random block design enabled the investigators to test the statistical difference in the effects of different vegetated and unvegetated treatments. They tested the degradation of diesel and polynuclear aromatic hydrocarbon components in plots containing three different vegetation treatments, two grasses and a legume, and a non-vegetated control. Part one of the monograph gives a complete and thorough account of the results of the field study. Part two covers the design and potential costs of a full-scale implementation of the demonstration system as well as the performance and potential application of the new technology. Phytoremediation of Hydrocarbon Contaminated Soils supplies quantitative results about the use of vegetation in soil remediation. The information given on the niches and limitations of the technologies allows for a more informed selection of remedial solutions for environmental cleanup.

This timely reference presents the state of the art of the emerging and rapidly changing field of bioremediation of chlorinated solvents, PCBs, and other chlorinated compounds, as well as PAHs, both in situ and on site. This landmark publication reports significant advances in bioremediation, with an emphasis on practical applications and state-of-the-art developments. Laboratory and field-oriented reviews are presented with the objective of tying treatability studies and recent laboratory developments to field applications. No other reference source gives you access to the most current techniques and methods for the bioremediation of chlorinated and polycyclic aromatic hydrocarbon compounds. This book represents the work of leading experts in the fields of in situ and on-site bioremediation from North America, Europe, and Asia. The chapters include current field applications and laboratory studies undertaken, in some cases, in countries with regulatory standards more stringent than those of the United States.

Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.

Arbuscular Mycorrhiza (AM) is the most common mycorrhizal type involved in agricultural systems, and the most widespread plant root symbiosis. The fungi involved (Glomales) are known to promote plant growth and health by acting as biofertilizers, bioprotectors and bioregulators. The main aim of this book is to provide readers with theoretical and applied knowledge essential for the use of AM fungi in improving plant health and fitness, production of high quality food and in conservation of natural resources. The different chapters target understanding the role of AM fungi in sustainable crop production, discussing ways to improve biological equilibria between microorganisms in the mycorrhizosphere, analysing genetic, physiological, cellular and molecular bases of AM functioning and establishing technologies for inoculum production, according to the regulatory guidelines for application.

Assisted 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
