Biodegradation is the break down of organic matter by microbes. Bioremediation is an engineered technique applied by people to clean up organic matter by helping microbes with the biodegradation process. One way of doing that is to introduce oxygen into the subsurface to help more aerobic microbes grow in order to clean up oil in the soil.The potential toxicity (harmful action) inherent in a substance is manifest only when that substance comes in contact with that susceptible living biological system. A chemical normally thought of as "e;harmless"e; will evoke a toxic response if added to a biological system in sufficient amount. The toxic potency of a chemicals is defined by the relationship between dose (the amount) of the chemical and the response that is produced in a biological system. The toxicity of industrial wastes is not often managed and it has caused serious damage to earth and water. The most important aspect of environmental biotechnology is the effective management of hazardous and toxic pollutants (xenobiotics) by bioremediation. The environmental clean-up process through bioremediation can be achieved in two ways-in situ and ex situ bioremediation. The book aims to provide relevant theoretical and practical frameworks and the latest empirical research findings in this area, along with case studies. It is written for students, academicians and industry professionals who want to improve their understanding of the strategic role of biodegradation and bioremediation at different levels of the biodegradation and bioremediation research and knowledge, that is, heavy metal pollution, toxicity, remediation methods and strategies to manage the waste in industries, which are a global concern.

FROM THE INTRODUCTION This three-volume series, Bioremediation: Principles and Practice, provides state of the art description of advances in pollution treatment and reduction using biological means; identify and address, at a fundamental level, broad scientific and technological areas that are unique to the subject or theme and that must be understood if advances are to be made; and provide a comprehensive overview of new developments at the regulatory, desk-top, bench-scale, pilot scale, and full-scale levels. The series covers all media-air, water, and soil/sediment-and blends the talents, knowledge, and know-how of academic, industrial, governmental, and international contributors. The series addresses the removal of both hazardous and nonhazardous contaminants from the liquid, solid, and gas phase using biological processes. This includes the biological treatment of wastes of municipal and industrial origin; bioremediation of leachates, soils, and sediments; and biofiltration for contaminated gases.

This synthesis will be of interest to state transportation personnel involved with project planning and location (administrative and regulatory personnel), design staff (general civil, geotechnical, and environmental engineers), and project managers (construction and maintenance engineers and staff). It will also be of interest to federal and state environmental agencies and to environmental consultants and contractors as well as to trainers in the field of petroleum-contaminated soil remediation. This synthesis describes the remedial technologies that may be available to transportation agencies faced with the regulatory responsibility to clean or remediate petroleum-contaminated soils in the vadose zone (unsaturated soils above the groundwater table) at a particular site as well as the state of the practice within the agencies. This report of the Transportation Research Board describes the applicability and cost-effectiveness of alternate technologies to remediate petroleum-contaminated soil. Practices currently being used by state transportation agencies to remediate petroleum-contaminated soils, both on site and off site are also described. This summary of transportation agency practice complements the limited telephone survey of soil remediation techniques that was performed in preparing NCHRP Report 351, Hazardous Wastes in Highway Rights-of-Way.

Encyclopedic in scope, this new book presents state-of-the-art methods and techniques demonstrating new applications for biotechnology to remediate contaminated sites. Researchers and practitioners world-wide share their collective evidence to demonstrate how biotechnology works, both alone and in combination with other remediation techniques. This essential tool will aid engineers and environmental practitioners in the planning of effective and economical remediation strategies. No other book provides such diverse information on specific biotechnology applications.

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.
