Volume 3 covers recent research with expanded coverage on this important area of remediation. Mycoremediation is the form of bioremediation in which fungi-based technology is used to decontaminate the environment. Fungi are among the primary saprotrophic organisms in an ecosystem, as they are efficient in the decomposition of organic matter. Wood-decay fungi, especially white rot, secretes extracellular enzymes and acids that break down lignin and cellulose. Fungi have been proven to be a very cost-effective and environmentally-friendly way for helping to remove a wide array of toxins from damaged environments or wastewater. These toxins include heavy metals, persistent organic pollutants, textile dyes, leather tanning industry chemicals and wastewater, petroleum fuels, polycyclic aromatic hydrocarbon, pharmaceuticals and personal care products, pesticides and herbicides, in land, fresh water and marine environments. Bioremediation of toxic organics by fungi is the most sustainable and green route for cleanup of contaminated sites and we discuss the multiple modes employed by fungi for detoxification of different toxic and recalcitrant compounds including prominent fungal enzymes viz., catalases, general lipase, laccases, peroxidases and sometimes intracellular enzymes, especially the cyrochrome P450 monooxygeneses. Fungi play an important role in the biogeochemical cycling of manganese and other redox-active metals, which is related to their ability to survive radiation and other oxidative challenges. This book covers recent research with more detail on the various types of fungi and associated fungal processes used to clean up wastes and wastewaters in contaminated environments, and discusses their potential for environmental applications.
Reviews of Environmental Contamination and Toxicology attempts to provide concise, critical reviews of timely advances, philosophy, and significant areas of accomplished or needed endeavor in the total field of xenobiotics, in any segment of the environment, as well as toxicological implications.
This book details the plant-assisted remediation method, "phytoremediation", which involves the interaction of plant roots and associated rhizospheric microorganisms for the remediation of soil contaminated with high levels of metals, pesticides, solvents, radionuclides, explosives, crude oil, organic compounds and various other contaminants. Each chapter highlights and compares the beneficial and economical alternatives of phytoremediation to currently practiced soil removal and burial practices.
Bioremediation is an eco-friendly, cost-effective and natural technology targeted to remove heavy metals, radionuclides, xenobiotic compounds, organic waste, pesticides etc. from contaminated sites or industrial discharges through biological means. Since this technology is used in in-situ conditions, it does not physically disturb the site unlike conventional methods i.e. chemical or mechanical methods.
Phytoremediation is an emerging technology that employs higher plants for the clean-up of contaminated environments. Basic and applied research have unequivocally demonstrated that selected plant species possess the genetic potential to accumulate, degrade, metabolize and immobilize a wide range of contaminants. The main focus of this volume is on the recent advances of technologies using green plants for remediation of various metals and metalloids. Topics include biomonitoring of heavy metal pollution, amendments of higher uptake of toxic metals, transport of heavy metals in plants, and toxicity mechanisms. Further chapters discuss agro-technological methods for minimizing pollution while improving soil quality, transgenic approaches to heavy metal remediation and present protocols for metal remediation via in vitro root cultures.
With remarkable vision, Prof. Otto Hutzinger initiated The Handbook of Envir- mental Chemistry in 1980 and became the founding Editor-in-Chief. At that time, environmental chemistry was an emerging ?eld, aiming at a complete description of the Earth's environment, encompassing the physical, chemical, biological, and geological transformations of chemical substances occurring on a local as well as a global scale. Environmental chemistry was intended to provide an account of the impact of man's activities on the natural environment by describing observed changes. While a considerable amount of knowledge has been accumulated over the last three decades, as re?ected in the more than 70 volumes of The Handbook of Environmental Chemistry, there are still many scienti?c and policy challenges ahead due to the complexity and interdisciplinary nature of the ?eld. The series will therefore continue to provide compilations of current knowledge. Contri- tions are written by leading experts with practical experience in their ?elds. The Handbook of Environmental Chemistry grows with the increases in our scienti?c understanding, and provides a valuable source not only for scientists but also for environmental managers and decision-makers. Today, the series covers a broad range of environmental topics from a chemical perspective, including methodol- ical advances in environmental analytical chemistry.
The first volume in this new text book series covers comprehensively relevant aspects related to the appearance and characterisation of fossil matter in the geosphere such as kerogen, oil, shales and coals. As organic geochemistry is a modern scientific subject characterized by a high transdisciplinarity and located at the edge of chemistry, environmental sciences, geology and biology, there clearly is a need for a flexible offer of appropriate academic teaching material on an undergraduat level addressed to the variety of students coming originally from different study disciplines. For such a flexible usage this textbook series' consists of different volumes with clear defined aspects and with manageable length.

This book brings together authors with expertise in a wide range of fields to provide an up to the minute overview of the most important problems relating to mercury in the environment. The book reflects growing concern over the likelihood of harmful effects to human health and sensitive ecosystems posed by mercury in the light of increasing fossil fuel combustion, mercury use in a range of manufactured goods, and the lack of emission control policies. Concern has been expressed at local, national, and international levels; in the last three years both the European Commission and UNEP have published reports on mercury in the environment. Growing concern has led to an increased effort to understand the fate of mercury in the environment, including primary production and trade in mercury, emissions from manufacturing and power generation, natural emissions and re-emission, atmospheric transport and transformation, deposition patterns, uptake by biota, and eventual health impacts on living organisms. The increasing specialisation, and amount of research in the numerous scientific fields associated with the study of the fate of mercury in the environment, make the publication of this book both necessary and timely. For experts, and non-experts, who require both the broader picture, as well as an awareness of the latest progress in the fields relevant to mercury research, this book provides the most comprehensive and up to date overview available. The book has five sections.

This book reviews alternative and renewable energy resources in order to pave the way for a more sustainable production in the future. A multi-disciplinary team of authors provides a comprehensive overview of current technologies and future trends, including solar technologies, wind energy, hydropower, microbial electrochemical systems and various biomass sources for biofuel production. In addition, the book focuses on solutions for developing countries. Conventional energy sources are finite, and estimates suggest that they will be exhausted within a few decades. Finding a solution to this problem is a global challenge, and developing countries in particular are still highly dependent on fossil fuels due to their rapidly growing populations accompanied by a huge growth in primary energy consumption. Moreover, the most common conventional energy sources (coal and petroleum) are non-sustainable since their combustion exponentially increases greenhouse gas emissions. As such, there is a pressing need for clean energy based on alternative or renewable resources, not only to ensure energy supplies at an affordable price but also to protect the environment.
An extensive evaluation of emission control technologies, models for estimating air emissions, and properties and categorization of wastes.
Most of the world s mountains are rich in water and, as such,
play a pivotal role in the global water cycle. They provide water
for diverse human uses and ecosystems. Growing water demands as
well as climate change will lead to ever-increasing pressure on
mountain waters. Overcoming water-use conflicts and maintaining the
ecological functioning of mountain waters presents a highly
challenging task and is indispensable for sustainable
development.

This book provides two state-of-the-art quantitative techniques to determine ultra-trace rare earth elements (REEs) in natural carbonates using solution nebulization-inductively coupled plasma mass spectrometry (SN-ICPMS) and laser ablation-inductively coupled plasma mass spectrometry (LA-ICPMS) with respective applications were presented in this dissertation. These techniques were applied to natural carbonates, including corals and stalagmites, to understand volcano eruptions and the impacts on modern biosystem and paleoclimate regimes. In the first SN-ICPMS protocol, direct measurements for femtogram quantity carbonate samples without chemical separation steps can offer accurate and high-precision analysis (+/-1.9-6.5%, 2 ) with a high sample throughput of 8-10 samples/hr routinely. Application to modern Porites corals collected from South China Sea region, the anomalies of REE contents and Al/Ca ratios associated with micro-domain images, register modern coral reefs could be exacerbated by volcanic eruptions. In the second protocol, a high-sensitivity quantitative open-cell LA-ICPMS technique has been established to allow direct sampling on stalagmite surface in the atmospheric air. This technique improved limits of detection down to sub-ng/g range and promises analyses of carbonate REE profiles at the single digit parts-per-billion (ppb) levels. Application to a 15-cm stalagmite collected from East Timor reveals two peaks of REE contents by at least one order of magnitude, possibly due to volcanic ash preserved in stalagmite. Both improved SN-ICPMS and LA-ICPMS techniques highlight the high-sensitivity and high-temporal-resolution carbonate REE analyses for corals and stalagmites, with great potential to other natural carbonates such as travertine, tufa, and flowstone, benefit our understanding of paleoclimatic and paleoenvironmental dynamics.

in Congress - are not considered, they may affect future energy programs just as they have past programs. Finally, potentially ruinously costly increases in energy imports force attention to the problem of how major public policy plans have been and are prepared in the United States. A witches' brew of some 500 energy bills proposed in the 110th C ongress in the House and Senate is now being stirred up. This "inspirational" approach to public policymaking bears little resemblance to the thoughtful way critical policies have been developed in the EU. A change of the way major national planning is undertaken may do more than anything else to bring facts and reality into play, reduce hostilities, open up cooperation, new resources, technologies, creative energies, and productivity toward energy policy transitions. Chapter 6 Foreign Experience 6. 1 The European Union and Other Nations Take the Lead "The EU has pioneered a new form of post-national government, in which nation-states pool some of their sovereignty for the common good. Many of its admirers see this as a useful potential model for Southeast Asia, the Indian subcontinent, China-Taiwan, Latin America, parts of Africa and so on. The EU takes some issues, like human rights, global warming and the fostering of an international system of justice, with admirable seriousness . . . . . . Considering the kind of Europe it replaced, the EU has been an almost miraculous success (Walker, 2007).

Science and politics are closely connected in today's global environmental issues. This book focuses on these links in relation to climate change, the threats to wildlife species, and natural hazards and disasters. Close study of these links of these reveals the need for more effective international cooperation and the limits of global governance.

Following release to the environment, synthetic chemicals may be degraded by biotic and abiotic processes. The degradation of the chemical can follow a plethora of pathways and a range of other substances can be formed via thesedifferentpathways(e.g.[1]).Anumberoftermshavebeenusedforthese substances including metabolites, degradates and transformation products - in this book we use the term transformation products. While we often know a lot about the environmental properties and effects of the parent synthetic chemical, we know much less about the transformationproducts. Transformationproductscanbehave very differently fromtheparent c- pound (e.g. [2]). For example, selected transformation products are much more persistent than their associated parent compound in soils, waters and sediments andsomemaybetransported aroundthelocal,regionalandglobal environmentstoadifferentextentthantheparentcompound.Transformation products can also have very different toxicities than the parent compound (e.g. [3]) and in some cases transformation products can be orders of mag- tude more toxic than their parent compound; although this situation is rare. The environmental risks of transformation products can therefore be very different than the risks of the parent compound. Thepotentialenvironmentalimpactsoftransformationproductsarerec- nised by many regulatory assessment schemes. For example, in the EU, pes- cideproducersarenotonlyrequiredtoassessthefateandeffectsoftheparent pesticide but are also required to assess the potential adverse effects of major metabolitesandminor metabolitesthat aredeemed tobeofconcern[4]. S- ilar requirements also exist for new human and veterinary pharmaceuticals and biocides (e.g. [5]). However, for many older substances and many other substance classes (e.g. industrial chemicals), data on the environmental risks of transformationproductscan be limited or non-existent.
Despite having been published about two years ago for the first time, the continuous demand for this book encouraged me to prepare this revised and enlarged edition. Many parts of the text have been rewritten, type errors traced and corrected, and the bibliography largely modified to include many of the references published about the subject of soil pollution in the previous ten years. I should like to express my thanks to the staff of Springer-Verlag, Heidelberg, for their cooperative efforts in preparing this edition. I also would like to thank Mr. Michael Sidwell (B.A.) for the extreme but characteristic care with which he read and revised the proofs. I hope that, in this new edition, the book may continue to serve the needs of students and professionals alike interested in the subject of soil pollution. Ibrahim A. Mirsal Preface to the First Edition Whoever has enjoyed following the legendary duel between the Egyptian Pharaoh and his magicians (Alchemists) on one side, and Moses and his brother Aaron on the other, as is vividly narrated in the Bible, must have realised that people (at least those living at, or near the eternal battlefields of the Middle East) have always had knowledge about the terrible consequences of soil pollution by chemicals. This knowledge must have existed long before Moses and his Pharaoh. Nobody knows when people became aware of this, yet it must have been born in very early times, reaching back to the dawn of human conscious. |
