Book Description
Remediation of environments contaminated with polycyclic aromatic hydrocarbons (PAHs) has received tremendous attention in recent times, owing, in particular to their acute carcinogenity and persistence for long lengths of time, remaining virtually unchanged in some cases for years. According to one estimate, the total remediation costs for individual manufactured gas plants (MGPs) normally range in tens of millions of dollars, and that remediation of tar contamination alone incurs as much as 70% of the total expenditure [Luthy et al., 1994]. This study delves into the possibility of remediating an MGP site extensively contaminated with PAHs by using an ex-situ solvent extraction method. Various solvent combinations consisting of ternary mixtures of water and some water miscible solvents like ethanol, propanol, acetone and pentanol have been considered. A rigorous study to simultaneously optimize the solvent combination, soil-solvent ratio and mixing regimen has also been conducted. The viability of solvent recovery and solvent reuse has also been addressed.

Book Description
This new edition discusses chemical and engineering principles as they apply to the cleanup and removal of hazardous chemicals from soil and groundwater. There is emphasis on environmental chemistry, soil science, microbiology, and plant science. The first part of the book provides an overview of the recent history of environmental contamination and the formulation of relevant regulations for hazardous waste site remediation. This part also provides a background for several salient aspects of site remediation (e.g., soil science, the site assessment process). The second part of the book examines field remediation technologies, including phytoremediation, bioremediation, and several chemical and physical technologies. Theory of operation, practical considerations, and possible environmental impacts and other consequences of their use are discussed. Covers both metal- and hydrocarbon-based contamination and remediation Many competitors only address one industry, or source, of contamination—this title provides an overview of all of the sources. Presents both the assessment of contaminated sites and the technologies currently available for environmental cleanup Effective for use in field situations and for academic (i.e., university course) use. Two new chapters: (i) the use of nanomaterials for remediation of contaminated soil and water; and (ii) revegetation of severely disturbed sites.

Book Description
This book provides an overview of the current development status of remediation technologies involving electrochemical processes, which are used to clean up soils that are contaminated with different types of contaminants (organics, inorganics, metalloids and radioactive). Written by internationally recognized experts, it comprises 21 chapters describing the characteristics and theoretical foundations of various electrochemical applications of soil remediation. The book’s opening section discusses the fundamental properties and characteristics of the soil, which are essential to understand the processes that can most effectively remove organic and inorganic compounds. This part also focuses on the primary processes that contribute to the application of electrochemically assisted remediation, hydrodynamic aspects and kinetics of contaminants in the soil. It also reviews the techniques that have been developed for the treatment of contaminated soils using electrochemistry, and discusses different strategies used to enhance performance, the type of electrode and electrolyte, and the most important operating conditions. In turn, the book’s second part deals with practical applications of technologies related to the separation of pollutants from soil. Special emphasis is given to the characteristics of these technologies regarding transport of the contaminants and soil toxicity after treatment. The third part is dedicated to new technologies, including electrokinetic remediation and hybrid approaches, for the treatment of emerging contaminants by ex-situ and in-situ production of strong oxidant species used for soil remediation. It also discusses pre-pilot scale for soil treatment and the use of solar photovoltaic panels as an energy source for powering electrochemical systems, which can reduce both the investment and maintenance costs of electrochemically assisted processes.

Book Description
This book presents WHO guidelines for the protection of public health from risks due to a number of chemicals commonly present in indoor air. The substances considered in this review, i.e. benzene, carbon monoxide, formaldehyde, naphthalene, nitrogen dioxide, polycyclic aromatic hydrocarbons (especially benzo[a]pyrene), radon, trichloroethylene and tetrachloroethylene, have indoor sources, are known in respect of their hazardousness to health and are often found indoors in concentrations of health concern. The guidelines are targeted at public health professionals involved in preventing health risks of environmental exposures, as well as specialists and authorities involved in the design and use of buildings, indoor materials and products. They provide a scientific basis for legally enforceable standards.

Book Description
Pollution is the release of chemical, physical, biological or radioactive contaminants to the environment. Principal forms of pollution include: air pollution, the release of chemicals and particulates into the atmosphere. Common examples include carbon monoxide, sulphur dioxide, chlorofluorocarbons (CFCs), and nitrogen oxides produced by industry and motor vehicles. Ozone and smog are created as nitrogen oxides and hydrocarbons react to sunlight. Water pollution affects oceans and inland bodies of water. Examples include organic and inorganic chemicals, heavy metals, petrochemicals, chloroform, and bacteria. Water pollution may also occur in the form of thermal pollution and the depletion of dissolved oxygen. Soil contamination often occurs when chemicals are released by spill or underground storage tank leakage. Contaminants include hydrocarbons, heavy metals, MTBE, herbicides, pesticides and chlorinated hydrocarbons. Often occurs with water pollution, thanks to surface runoff and groundwater. Radioactive contamination was added in the wake of 20th-century discoveries in atomic physics. Noise pollution encompasses roadway noise, aircraft noise, industrial noise as well as high-intensity sonar. Light pollution, includes light trespass, over-illumination and astronomical interference. Visual pollution, which can refer to the presence of overhead power lines, highway billboards, scarred landforms (as from strip mining), open storage of junk or municipal solid waste. The nature, distribution and ecological effects of all types and forms of pollutants in air, soil and water are the subject of this book.

Book Description
The book describes hazardous waste industries, sources of waste generation, characterization and treatment processes/ methods and technique and technology to deal with the treated waste as per the prescribed standard. Advanced treatment based on the microbial remediation, plant-based decontamination, rhizoremediation and nano-based remediation is also explained. Advances in treatment technology using biotechnological tools/bionanotechnology for removal of contaminants are described. This volume will help readers to develop biotechnological and nanotechnological approaches for the remediation of hazardous waste and the developed technology that can be transferred from laboratory to land and piloting to commercial scenarios.
