This book was released on 2011-05-16 with total page 922 pages. Available in PDF, EPUB and Kindle. Book excerpt: In contrast to the classical books which largely focus on separate, individual physicochemical and biological aspects, this book aims to integrate the frontiers of knowledge on the fundamentals and the impact of physicochemical and biological interactions and processes of AOCs in soil, sediment, water and air. The specific objectives of this book are to address: (1) fundamental biophysico-chemical processes of AOCs in the environment, (2) occurrence and distribution of AOCs in air, water, and soil, and their global cycling, (3) the state-of-the-art analytical techniques of AOCs, and (4) restoration of natural environments contaminated by AOCs. The book also identifies the gaps in knowledge on the subject matter and as such provides future directions to stimulate scientific research to advance the chemical science on biophysico-chemical interfacial reactions in natural habitats. By virtue of complex nature of the interactions of AOCs with different environmental components and matrixes, no single available technique and instrument is satisfactory yet for determining their fate, transport, availability, and risk in the environment. In order to fully understand the biophysico-chemical interactions and processes of AOCs in the environment, it is critical to know chemical, physical and biological properties of AOCs and their analytical techniques. The book is unique because of its multidisciplinary approach as it provides a comprehensive and integrated coverage of biophysico-chemical reactions and processes of AOCs in various environments, associated analytical techniques, and restoration of natural environments contaminated by AOCs.

Download or read book Partition and Adsorption of Organic Contaminants in Environmental Systems written by Cary T. Chiou and published by John Wiley & Sons. This book was released on 2003-07-07 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given the presence of a wide variety of contaminants in the environment, it is important to understand what drives a contaminant from one medium to another, as well as the manner and extent to which a contaminant associates with the different media or phases within a local environmental system. Partition and Adsorption of Organic Contaminants in Environmental Systems forms a comprehensive resource on the behavioral characteristics of contaminants so that appropriate strategies can be adopted to either prevent or minimize their adverse impacts on human welfare and natural resources. Cary Chiou’s far-reaching text depicts the processes by which nonionic organic contaminants are sorbed to natural biotic and abiotic substances. This book focuses on physical principles and system parameters that affect the contaminant uptake by soil from water, air, and other media; by fish from water; and by plants from soil and water. As contaminant uptake by natural organic substances is often predominantly a partition interaction, the partition characteristics in several solvent-water model mixtures are treated in detail to elucidate the relevant physicochemical parameters. The account of contaminant sorption to soils, fish, and plants is strengthened by companion chapters on: Fundamentals of solution theory Interphase partition equations Fundamentals of adsorption theory Vapor adsorption on mineral and carbonaceous solids No other single source in the field delivers as compelling a combination of background understanding and "state-of-the-science" comprehension of current issues. Ideally suited for a graduate-level environmental course, Partition and Adsorption of Organic Contaminants in Environmental Systems also serves as a technical guide to current and future research in the field.

Download or read book Use of Humic Substances to Remediate Polluted Environments From Theory to Practice written by Irina V. Perminova and published by Springer Science & Business Media. This book was released on 2006-04-07 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective remediation of polluted environments is a priority in both Eastern and Western countries. In the U.S. and Europe, remediation costs generally exceed the net economic value of the land. As a result, scientists and engineers on both sides of the Atlantic have aggressively tried to develop novel technologies to meet regulatory standards at a fraction of the costs. In situ remediation shows considerable promise from both technical and economic perspectives. In situ technologies that deploy natural attenuating agents such as humic substances (HS) may be even more cost effective. Numerous studies have shown humics capable of altering both the chemical and the physical speciation of the ecotoxicants and in turn attenuate potential adverse environmental repercussions. Furthermore, the reserves of inexpensive humic materials are immense. Which suggests HS portend great promise as inexpensive amendments to mitigate the environmental impacts of ecotoxicants and as active agents in remediation. To elucidate emerging concepts of humics-based remediation technologies, we organized the NATO Advanced Research Workshop (ARW), entitled "Use of humates to remediate polluted environments: from theory to practice", held on September 23-29, 2002 in Zvenigorod, Russia (see the web-site http://www.mgumus.chem.msu.ru/arw).
Download or read book Bioavailability of Contaminants in Soils and Sediments written by National Research Council and published by National Academies Press. This book was released on 2003-05-03 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioavailability refers to the extent to which humans and ecological receptors are exposed to contaminants in soil or sediment. The concept of bioavailability has recently piqued the interest of the hazardous waste industry as an important consideration in deciding how much waste to clean up. The rationale is that if contaminants in soil and sediment are not bioavailable, then more contaminant mass can be left in place without creating additional risk. A new NRC report notes that the potential for the consideration of bioavailability to influence decision-making is greatest where certain chemical, environmental, and regulatory factors align. The current use of bioavailability in risk assessment and hazardous waste cleanup regulations is demystified, and acceptable tools and models for bioavailability assessment are discussed and ranked according to seven criteria. Finally, the intimate link between bioavailability and bioremediation is explored. The report concludes with suggestions for moving bioavailability forward in the regulatory arena for both soil and sediment cleanup.

Download or read book Environmental Toxicology II written by C. A. Brebbia and published by WIT Press. This book was released on 2008 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental toxicology is one of the most interdisciplinary sciences. Biologists, microbiologists, chemists, engineers, environmentalists, ecologists and other scientists work together in this new scientific discipline. Assessment of the environmental effects of chemicals is complicated as it depends on the organisms tested and involves not only the toxicity of individual chemicals, but also their interactive effects (including antagonistic and synergistic ones), and genotoxicity, mutagenicity and immunotoxicity testing. Hazardous waste management is closely related to environmental toxicology and there is a growing need for techniques and practices to minimize the environmental effects of chemicals. This volume contains the contributions presented at the 2nd Conference on Environmental Toxicology, which was held in Granada, Spain in 2008. The papers cover the following subject areas: Risk Assessment; Human Health Risk; Effluent Toxicity; Bioaccumulation of Chemicals; Biodegredation and Bioremediation; Biological Effects Monitoring; Laboratory Tests and Validation; Ecotoxicity of Emerging Chemicals; New Trends in Environmental Toxicology.
