Written by an expert, using the same approach that made the previous two editions so successful, Fundamentals of Environmental Chemistry, Third Edition expands the scope of book to include the strongly emerging areas broadly described as sustainability science and technology, including green chemistry and industrial ecology. The new edition includes: Increased emphasis on the applied aspects of environmental chemistry Hot topics such as global warming and biomass energy Integration of green chemistry and sustainability concepts throughout the text More and updated questions and answers, including some that require Internet research Lecturers Pack on CD-ROM with solutions manual, PowerPoint presentations, and chapter figures available upon qualifying course adoptions The book provides a basic course in chemical science, including the fundamentals of organic chemistry and biochemistry. The author uses real-life examples from environmetnal chemistry, green chemistry, and related areas while maintaining brevity and simplicity in his explanation of concepts. Building on this foundation, the book covers environmental chemistry, broadly defined to include sustainability aspects, green chemistry, industrial ecology, and related areas. These chapters are organized around the five environmental spheres, the hydrosphere, atmosphere, geosphere, biosphere, and the anthrosphere. The last two chapters discuss analytical chemistry and its relevance to environmental chemistry. Manahan’s clear, concise, and readable style makes the information accessible, regardless of the readers’ level of chemistry knowledge. He demystifies the material for those who need the basics of chemical science for their trade, profession, or study curriculum, as well as for readers who want to have an understanding of the fundamentals of sustainable chemistry in its crucial role in maintaining a livable planet.

Water has become one of the most important issues of our time intertwined with global warming and population expansion. The management of water supplies and the conservation of water resources remains one of the most challenging yet exciting issues of our time. Water and wastewater treatment technologies are constantly evolving creating an increasingly sustainable industry that is one of the world's largest and most interdisciplinary sectors, employing chemists, microbiologists, botanists, zoologists as well as engineers, computer specialists and a range of different management professionals. This accessible student textbook introduces the reader to the key concepts of water science and technology by explaining the fundamentals of hydrobiology, aquatic ecosystems, water treatment and supply, wastewater treatment and integrated catchment management. This fourth edition is extensively changed throughout, with new coverage of the effects of climate change, environmental assessment, sustainability and the threat to biodiversity. The text serves as a primer for both undergraduate and graduate students in either science or engineering who have an interested in freshwater biology/hydrobiology or environmental engineering. It is also useful as a unified transitional course for those who want to span the traditional areas of engineering, biology, chemistry, microbiology or business. Professionals and consultants will also find the book a useful reference.

Information modelling and knowledge bases have become ever more essential in recent years because of the need to handle and process the vast amounts of data which now form part of everyday life. The machine to machine communication of the Internet of Things (IoT), in particular, can generate unexpectedly large amounts of raw data. This book presents the proceedings of the 27th International Conference on Information Modelling and Knowledge Bases (EJC2017), held in Krabi, Thailand, in June 2017. The EJC conferences originally began in 1982 as a co-operative initiative between Japan and Finland, but have since become a world-wide research forum bringing together researchers and practitioners in information modelling and knowledge bases for the exchange of scientific results and achievements. Of the 42 papers submitted, 29 were selected for publication here, and these cover a wide range of information-modelling topics, including the theory of concepts, semantic computing, data mining, context-based information retrieval, ontological technology, image databases, temporal and spatial databases, document data management, software engineering, cross-cultural computing, environmental analysis, social networks, and WWW information. The book will be of interest to all those whose work involves dealing with large amounts of data.

The Symposium was dedicated to the late George Burke Maxey and the keynote address was givern by Courney Riordan ... A debate format on "The issues of our time" featured national authorities presenting neutral, pro, and con views followed by audience reaction, and addressed nin topics: * Ground water pollution--an imminent disaster or limited problem; * Ground water quality standards--necessary or irrelevant; * Land application of waste--an important future alternative or an accident waiting to happen; * The federal ground water protection program--today's hope or tomorrow's undoing; * State ground water protection programs--adequate or inadequate; * The 208 planning approach to ground water protection--a terrible joke or a foot in the door; * Controlled degradation and/or protection zones--sense or nonsence; *Ground water models--practical tools or intellectual toys; * water borne disease--a current threat or a thing of the past."--Page iv.

The Congress "Arsenic in the Environment" offers an international, multi- and interdisciplinary discussion platform for research and innovation aimed towards a holistic solution to the problem posed by the environmental toxin arsenic, with considerable societal impact. The congress has focused on cutting edge and breakthrough research in physical, chemical, toxicological, medical, agricultural and other specific issues on arsenic across a broader environmental realm. The Congress "Arsenic in the Environment" was first organized in Mexico City (As2006) followed by As2008 in Valencia, Spain, As2010 in Tainan, Taiwan, As2012 in Cairns, Australia and As2014 in Buenos Aires, Argentina. The 6th International Congress As2016 was held June 19-23, 2016 in Stockholm, Sweden and was entitled Arsenic Research and Global Sustainability. The Congress addressed the broader context of arsenic research along the following themes: Theme 1: Arsenic in Environmental Matrices and Interactions (Air, Water, Soil and Biological Matrices) Theme 2: Arsenic in Food Chain Theme 3: Arsenic and Health Theme 4: Clean Water Technology for Control of Arsenic Theme 5: Societal issues, Policy Studies, Mitigation and Management Long term exposure to low-to-medium levels of arsenic via contaminated food and drinking water can have a serious impact on human health and globally, more than 100 million people are at risk. Since the end of the 20th century, arsenic in drinking water (mainly groundwater) has emerged as a global health concern. In the past decade, the presence of arsenic in plant foods – especially rice – has gained increasing attention. In the Nordic countries in particular, the use of water-soluble inorganic arsenic chemicals (e.g. chromated copper arsenate, CCA) as wood preservatives and the mining of sulfidic ores have been flagged as health concern. The issue has been accentuated by discoveries of naturally occurring arsenic in groundwater, primarily in the private wells, in parts of the Fennoscandian Shield and in sedimentary formations, with potentially detrimental effects on public health. Sweden has been at the forefront of research on the health effects of arsenic, technological solutions for arsenic removal, and sustainable mitigation measures for developing countries. Hosting this Congress in Sweden was also relevant because historically Sweden has been one of the leading producer of As2O3 and its emission from the smelting industries in northern Sweden and has successfully implemented actions to reduce the industrial emissions of arsenic as well as minimizing the use of materials and products containing arsenic in since 1977. The Congress has gathered professionals involved in different segments of interdisciplinary research in an open forum, and strengthened relations between academia, industry, research laboratories, government agencies and the private sector to share an optimal atmosphere for exchange of knowledge, discoveries and discussions about the problem of arsenic in the environment and catalyze the knowledge generation and innovations at a policy context to achieve the goals for post 2015 Sustainable Development.
