This book was released on 1994-02-28 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Biodegradation and Relese of Polycyclic Aromatic Hydrocarbons from Natural Organic Matter Surrogates written by Christopher Michael Hurdzan and published by . This book was released on 2006 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: A recent study demonstrated that mono-hydroxylated pyrene and benzo[a]pyrene are formed in the human large intestine as a result of metabolism by enteric microorganisms. This is the only documentation of the anaerobic biodegradation of the higher (greater than three rings) polycyclic aromatic hydrocarbons (PAHs). The detection of carboxylated and methylated intermediates formed during the anaerobic mineralization of naphthalene in environmental samples suggest that the anaerobic biodegradation of higher PAHs may produce a variety of terminal or intermediate metabolites in addition to mono-hydroxylates. To investigate this possibility, phenanthrene, pyrene and benzo[a]pyrene were incubated within a suspension of human enteric microorganisms under various treatment conditions. No metabolites were detected. These findings suggest that the biodegradation of PAH is not a major metabolic process of the human large intestine. Recent studies have demonstrated that the aliphatic region of natural organic matter (NOM) can retain appreciable quantities of polycyclic aromatic hydrocarbons (PAHs) due to the presence of non-polar binding sites. Ingested NOM-associated PAH (e.g., benzo[a]pyrene) may be released in the human gastrointestinal tract and converted by liver hepatocytes to various mutagenic or carcinogenic metabolites following absorption. In this study, the release of phenanthrene from the aliphatic NOM surrogates cutin and cutan was measured under simulated human gastrointestinal conditions using three treatments designed to simulate the 1) biological, 2) chemical and 3) biological and chemical conditions of the gastrointestinal environment. Cutin was found to yield an average phenanthrene release 55% higher than cutan (94% vs. 39%). A significant decrease in phenanthrene release was observed in both the additions and additions + fecal treatments as compared to the water treatment (control). The presence of fecal microorganisms did not significantly influence phenanthrene release and did not contribute to a reduced phenanthrene bioaccessibility in gastrointestinal chyme. The results of this study demonstrate that phenanthrene bioaccessibility under simulated human gastrointestinal conditions is significantly influenced by the physical structure of the sorbent matrix as well as the abiotic component of gastrointestinal chyme.

Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Bioremediation: Physiological, Molecular and Biotechnological Interventions discusses the mechanisms of responding to inorganic and organic pollutants in the environment using different approaches of phytoremediation and bioremediation. Part One focuses specifically on inorganic pollutants and the use of techniques such as metallothionein-assisted remediation, phytoextraction and genetic manipulation. Part Two covers organic pollutants and consider topics such as plant enzymes, antioxidant defense systems and the remediation mechanisms of different plant species. This comprehensive volume is a must-read for researchers interested in plant science, agriculture, soil science and environmental science. The techniques covered in this book will ensure scientists have the knowledge to practice effective bioremediation techniques themselves. Provides a comprehensive review of the latest advances in bioremediation of organic and inorganic pollutants Discusses a range of different phytoremediation techniques Evaluates the role of genomics and bioinformatics within bioremediation

Available in PDF, EPUB and Kindle. Book excerpt: Our Earth is considered as a natural system which organizes and controls itself. However, the present scale of anthropogenic activity is unprecedented in the history of mankind compelling the intelligentia to ponder over the scientific causes of the problems, processes and sustainable and pragmatic solutions. The current rate of resource use and consumption pattern are depleting the planet’s finite resources and damaging life-supporting ecosystems. A large number of toxic substances are increasingly found in air, water, soil, and flora and fauna. We are in the midst of a period of increasing interconnected and complex global challenges that seek action across temporal and spatial scales, diverse sectors, and concerted efforts from global citizens. The environment on account of human’s action has been experiencing imbalances and ecological catastrophe. Environmental issues like global climate change, biodiversity loss, the rapid depletion of natural resources, degradation of global commons, stratospheric ozone depletion have been restricting the safe operating space and transgressing the planetary boundaries endangering the existence of human societies. The global environmental problems if not scientifically managed may end up in the civilizational collapse. Nevertheless, the underlying commonality among these environmental issues is interrelatedness, complexity, and difficulty in identifying and implementing solutions. The global environmental challenges can be managed by adopting sustainable green technologies which dovetails the principles of environmental sustainability with social and ecological sustainability. Green growth is construed as a new development paradigm that sustains economic growth while at the same time ensuring environmental sustainability.

This book was released on 2000 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carnegie Mellon University and Stanford University investigated the anaerobic biodegradation of polycyclic aromatic hydrocarbons (PAHs) in contaminated sediments under bioslurry denitrifying conditions. Samples from sediment bioslurry tests and toxicity bioassays were used to assess PAH bioavailability as inferred from subparticle-scale measurement of PAH locations on sediment particles and association with sorbent organic matter. The research employed new microscale, analytic measurement techniques: microprobe, two-step laser desorption/laser ionization mass spectrometry; infrared microspectroscopy; wavelength dispersive X-ray analysis; and thermal desorption mass spectrometry. These techniques provide information on subparticle-scale PAH distributions in sediment. CMU researchers have reviewed relevant studies, cultivated Pseudomonas putida KBM1, a strain of microorganisms capable of degrading PAHs under denitrifying conditions, and conducted anaerobic and aerobic PAH degradation studies. R G. Luthy has leveraged the experimental studies with a major Gas Research Institute initiative on environmentally acceptable endpoints. CMU and Stanford have examined PAH distribution on dredged Milwaukee harbor sediment obtained from the Jones Island confined disposal facility. Subparticle-scale analyses have shown that PAH sorption involves near-surface sorption processes, rather than particle-scale diffusion phenomena, and that coal-like particles contain many times more PM's than silica particles. Results from anaerobic and aerobic biodegradation experiments conducted with two PAH contaminated sediments are presented in this final report.
