Book Description
Around the World, metal pollution is a major problem. Conventional practices of toxic metal removal can be ineffective and/or expensive, delaying and exacerbating the crisis. Those communities dealing with contamination must be aware of the fundamentals advances of microbe-mediated metal removal practices because these methods can be easily used and require less remedial intervention. This book describes innovations and efficient applications for metal bioremediation for environments polluted by metal contaminates.

Book Description
Inhaltsangabe:Introduction: Rapid industrialisation and growth in population over the past two hundred years exert an increasing pressure on natural resources and the environment. Billions of tons of controlled and scheduled waste are generated every year by the industrial sector worldwide which is often either pre-treated on-site or at a licensed contractor prior to disposal in landfills. This practice if continued is leading to resource depletion and creates a potentially harmful legacy for future generations. In order to move towards a more sustainable development as outlined in the Bruntland Report, waste reduction, reuse and recycling coupled with pollution prevention measures play an important part to slow down if not reverse this practice. Heavy metals such as cadmium, mercury, lead and chromium are not degradable or renewable like biomass hence if they are to be used in future processes reuse and recycling are the only options. At present, heavy metals are used in the chemical industry sector for applications ranging from batteries to catalysts and surface coatings, and can be found at various concentrations in gaseous, liquid or solid waste. Chromium is of particular interest owing to its legislative status and unique chemistry. Chromium exists in nature primarily in one of two oxidation states. There are other chemical oxidation states of chromium, which include 0, II, IV, and V, but they are considered transitory compared to more stable Cr(III) and Cr(VI) species. Hexavalent chromium is a strong oxidizer which can react with DNA causing mutation, while the trivalent, organically complex form is a dietary supplement to help with proper glucose metabolism, weight loss and muscle tone. Unlike many other metals, Cr(VI) can combine with oxygen to form water-soluble, negatively charged anions known as yellow chromate (CrO42-) or orange dichromate (Cr2O72-), which adsorb to positively charged sites in contrast to cationic metal species. Therefore, hexavalent chromium species are not strongly bonded in many soils under alkaline to slightly acidic conditions, for example. Thus, they can be very mobile in subsurface environment while other metals precipitated out and exert toxic effects on biological systems. Various well-established methods may be used to treat industrial effluents and contaminated water such as reduction and precipitation, reverse osmosis, evaporation, ion exchange and adsorption. While these processes are able to remove [...]

Book Description
The awareness of environment protection is a great achievement of humans; an expression of self-awareness. Even though the idea of living while protecting the environment is not new, it has never been so widely and deeply practiced by any nations in history like it is today. From the late 90s in the last century, the surprisingly fast dev

Book Description
This edited book brings together a diverse group of environmental science, sustainability, and health researchers to address the challenges posed by global mass poisoning caused by chromium contamination of soil and plants. In recent years, contamination of the environment by chromium has become a major concern. Chromium is a non-degradable, harmful, and toxic pollutant which negatively affects the environment. It is unique among the heavy metals found in industrial wastewater and sewage and sludge, as it may exist as a trivalent cation and as anion in the hexavalent state in the pH range of agricultural soils. It is used on a large scale in many different industries, including metallurgy, electroplating, production of paints and pigments, tanning, wood preservation, chemical production, and pulp and paper production. These industries are contributing larger amount of chromium, which can ultimately have significant adverse effects on biological and ecological activities of ecosystem. Chromium enters the food chain through consumption of plant material. A high concentration of chromium has been found to be harmful to vegetation. As the chromium concentration in plants increases, it adversely affects several biological parameters and eventually renders the soil barren. The book sheds light on this global environmental issue and proposes solutions to contamination through multi-disciplinary approaches and case studies from different parts of the world. This book is a valuable resource to students, academicians, researchers, and environmental professionals who are doing field work on chromium contamination throughout the world.

Book Description
The most comprehensive and up-to-date volume on environmental analysis available today, this is the standard laboratory reference for any environmental or chemical engineer, chemist, or scientist. Today, environmental issues are a great cause of concern at the global level, and universities and other institutions around the world are involved in research on climate change, deforestation, pollution control, and many other issues. Moreover, environmental science and environmental biotechnology are inherent parts of various courses while some universities provide degrees in these fields. Although the environment perspective of water is discussed time and again in research, academic, and non-academic discussions, there is no book summarizing protocols involved in water quality analysis. The information seems to be sporadically distributed on the internet. Even if available at all, the information does not discuss limits of the protocols or caveats involved. For example, essays on chemical oxygen demand (COD) on the internet mostly do not discuss differences between organic compounds of biological origin and aliphatic/aromatic. The authors have performed nearly all the protocols mentioned in this new volume, and their protocols are discussed in a simplified, easy-to-understand manner. The book has been written after elaborative discussions with and input from faculty and research students to ensure the clarity of the material for use on many levels. Further, the authors have emphasized low-cost methods which involve minimal use of high-end instrumentation keeping in mind limitations faced in developing countries. A valuable reference for engineers, scientists, chemists, and students, this volume is applicable to many different fields, across many different industries, at all levels. It is a must-have for any library.

Book Description
Pollution due to various anthropogenic activities continues to increase. In terms of water pollutants, organic and inorganic pollutants are the most problematic. Although several measures have been proposed and implemented to prevent or reduce contamination, their increased concentration in water bodies has created serious concerns. Over the years, the problem has been aggravated by industrialization, urbanization and the exploitation of natural resources. The direct discharge of wastewater contaminants and their geographical mobilization have caused an increase in concentration in ground, surface, fluvial and residual waters. Extensive information about detection and disposal methods is needed in order to develop technological solutions for a variety of environments, both urban and rural. This book provides up-to-date information on wastewater contaminants, aimed at researchers, engineers and technologists working in this field. Conventional physicochemical techniques used to remove contaminants from wastewater include ion exchange, precipitation, degradation, coagulation, coating, membrane processes and adsorption. However, these applications have technological and economic limitations, and involve the release of large amounts of chemical reagents and by-products that are themselves difficult to remove. Biosorption - the use of organically generated material as an adsorbent – is attracting new research and scholarship. Thermally-treated calcined biomaterials may be treated to remove heavy metals from wastewater. To ensure the elimination of these contaminants, existing solutions must be integrated with intelligent biosorption functions. Biosorption for Wastewater Contaminants will find an appreciative audience among academics and postgraduates working in the fields of environmental biotechnology, environmental engineering, wastewater treatment technology and environmental chemistry.
