Pollution has no borders. This popular 70's saying from early ecologists is surprisingly still true nowadays despite overwhelming scientific evidence and public awareness of the occurrence of artificial toxic substances in water, food, air, living organisms and the environment. This book presents advanced reviews on pollutant occurrence, transfer, toxicity and remediation. The chapter on school air quality by Dambruoso et al. highlights the overlooked health issue of airborne pollutants in buildings. Children are particularly threatened because they spend 90% of their time indoors, even in summer. The chapter on industrial wastewater pollutants by Dsikowitzky and Schwarzbauer reviews pollutants from textile, petrochemical, paper, tire, chemical and pharmaceutical plants. The authors describe advanced analytical methods and ecotoxicity tests. Industrial pollutants include dioxins and furans that are also reviewed in the chapter by Mudhoo et al. The chapter on fly ash by Gianoncelli et al. presents many techniques to treat fly ash and, in turn, decrease pollutant concentrations. The authors also explain that fly ash can be recycled in agriculture, buildings and geopolymers. The chapter on antifouling paints used for ship protection, by Sousa et al., highlights the occurrence of toxic organotins in human organs such as heart, liver and breast milk. The chapter on surfactants by Rebello et al. focuses on safety concerns for humans and the ecosystems. Remediation techniques and green surfactants are presented. The chapters on toxic metals by Nava-Ruiz and Mendez-Armenta, Abarikwu and Ristic et al. describe sources, monitoring and diseases induced by lead, mercury, cadmium and thallium. The chapter on carcinogenic nitrosamines by Li et al. presents techniques and materials such as zeolites to remediate liquids and smoke containing nitrosamines.
The Economic Feasibility of Recycling: A Case Study of Plastic Wastes is the first book to provide a general overview of the major issues at the heart of the recycle/disposal question. Analyzing in nontechnical language the incentives for and barriers to recycling, this new work examines a broad range of topics, including: the various recycle processes, how the various disposal methods affect the environment, what role the public and private sectors play in the decision-making process.
<b>Learn to correct icing and pollution problems in electrical line insulation</b> <p> Written by prominent experts in the field, this book takes an in-depth look at the issues of electrical insulators for icing and polluted environments. It shows: <ul> <li> <p> <b>Engineers and environmental specialists</b> how to carry out appropriate insulator contamination measurements, understand how these readings change with time and weather, and work out how the readings compare with the upper limits set by insulator dimensions in their existing stations <li> <p> <b>Design engineers</b> how to assess the likely maximum pollution and icing limits at a substation or along an overhead line, and then select insulators that have appropriate withstand margins <li> <p> <b>Regulators</b> why modest ice accretion at a moderate 0<sup>o</sup>C temperature on one occasion can qualify as a major reliability event day, while many similar days pass each winter without power system problems <li> <p> <b>Educators</b> why the ice surface flashover is well behaved compared to the conventional pollution flashover, making it much more suitable for demonstrations, modeling, and analysis </ul> <p> The book is complemented with case studies and design equations to help readers identify the most appropriate insulators, bushings, and maintenance plans for their local conditions. Additionally, readers may download supplemental materials supporting evaluation of local climate and contamination. <p> <i>Insulators for Icing and Polluted Environments</i> is indispensable reading for any professional who needs reliable electrical supply from networks exposed to sources of wetting and pollution. It also serves as an excellent introduction to the subjects of high-voltage surface flashover, environmental electrochemistry, and insulation coordination for researchers, professors, and students.
Curious George wants to help clean up the planet, and recycling seems like a good place to start-but where does he begin? Follow along with George as he learns about what recycling is, how it works, and what else he can do to reduce his monkey paw print. Readers will learn the difference between recycling and trash, what happens to the things we throw away, and other ways to help keep our planet clean. Based on Curious George, the Emmy Award-winning PBS TV show, this story also includes fun facts, real photos, experiments, activities, and more. Learning about science has never been so much fun! AGES: 4-7 AUTHOR: Hans Augusto Rey was born in Hamburg, Germany in 1898. As a child, he spent much of his free time in that city's famous Hagenbeck Zoo drawing animals. After serving in the army during World War I, he married Margret Rey and they moved to Montmartre for four years. The manuscript for the first Curious George books was one of the few items the Reys carried with them on their bicycles when they escaped from Paris in 1940. Eventually, they made their way to the United States, and Curious George was published in 1941. Curious George has been published in numerous languages. And many, many Curious George books have followed.
