Book Description
Contaminated sediments represent an ongoing threat to the health of aquatic ecosystems. The assessment of sediment quality is, therefore, an important concern for environmental regulators. Sediment quality guidelines are now well established in regulatory frameworks worldwide; however, practical guidance that covers all of the key aspects of sediment quality assessment is not readily available. In 2005, CSIRO published its highly cited Handbook for Sediment Quality Assessment. In the ensuing period, the science has advanced considerably. This practical guide is a revised and much expanded second edition, which will be a valuable tool for environmental practitioners. Written by experts in the field, it provides coverage of: sediment sampling; sample preparation; chemical analysis; ecotoxicology; bioaccumulation; biomarkers; and ecological assessment. In addition, detailed appendices describe protocols for many of the tests to be used.

Book Description
The landscape of the Calumet, an area that sits astride the Indiana-Illinois state line at the southern end of Lake Michigan was shaped by the glaciers that withdrew toward the end of the last ice age--about 45,000 years ago. In the years since, many natural forces, including wind, running water, and the waves of Lake Michigan, have continued to shape the land. The lake's modern and ancient shorelines have served as Indian trails, stagecoach routes, highways, and sites that have evolved into many of the cities, towns, and villages of the Calumet area. People have also left their mark on the landscape: Indians built mounds; farmers filled in wetlands; governments commissioned ditches and canals to drain marshes and change the direction of rivers; sand was hauled from where it was plentiful to where it was needed for urban and industrial growth. These thousands of years of weather and movements of peoples have given the Calumet region its distinct climate and appeal.

Book Description
There is need in environmental research for a book on fresh waters including rivers and lakes. Compared with other books on the topic, this book has a unique outline in that it follows pollution from sources to impact. Included in the text is the treatment of various tracers, ranging from pathogens to stable isotopes of elements and providing a comprehensive discussion which is lacking in many other books on pollution control of natural waters. Geophysical processes are discussed emphasizing mixing of water, interaction between water and the atmosphere, and sedimentation processes. Important geochemistry processes occurring in natural waters are described as are the processes specific to nutrients, organic pollutants, metals, and pathogens in subsequent chapters. Each of these chapters includes an introduction on the selected groups, followed by the physicochemical properties which are the most relevant to their behavior in natural waters, and the theories and models to describe their speciation, transport and transformation. The book also includes the most up to date information including a discussion on emerging pollutants such as brominated and phosphate flame retardants, perflurochemicals, and pharmaceutical and personal care products. Due to its importance an ecotoxicology chapter has been included featuring molecular biological methods, nanoparticles, and comparison of the basis of biotic ligand model with the Weibull dose-response model. Finally, the last chapter briefly summarizes the regulations on ambient water quality.

Book Description
Some of the nation's estuaries, lakes and other water bodies contain contaminated sediments that can adversely affect fish and wildlife and may then find their way into people's diets. Dredging is one of the few options available for attempting to clean up contaminated sediments, but it can uncover and re-suspend buried contaminants, creating additional exposures for wildlife and people. At the request of Congress, EPA asked the National Research Council (NRC) to evaluate dredging as a cleanup technique. The book finds that, based on a review of available evidence, dredging's ability to decrease environmental and health risks is still an open question. Analysis of pre-dredging and post-dredging at about 20 sites found a wide range of outcomes in terms of surface sediment concentrations of contaminants: some sites showed increases, some no change, and some decreases in concentrations. Evaluating the potential long-term benefits of dredging will require that the U.S. Environmental Protection Agency step up monitoring activities before, during and after individual cleanups to determine whether it is working there and what combinations of techniques are most effective.

Book Description
Every city has an environmental story, perhaps none so dramatic as Pittsburgh's. Founded in a river valley blessed with enormous resources-three strong waterways, abundant forests, rich seams of coal-the city experienced a century of exploitation and industrialization that degraded and obscured the natural environment to a horrific degree. Pittsburgh came to be known as "the Smoky City," or, as James Parton famously declared in 1866, "hell with the lid taken off."Then came the storied Renaissance in the years following World War II, when the city's public and private elites, abetted by technological advances, came together to improve the air and renew the built environment. Equally dramatic was the sweeping deindustrialization of Pittsburgh in the 1980s, when the collapse of the steel industry brought down the smokestacks, leaving vast tracks of brownfields and riverfront. Today Pittsburgh faces unprecedented opportunities to reverse the environmental degradation of its history. In Devastation and Renewal, scholars of the urban environment post questions that both complicate and enrich this story. Working from deep archival research, they ask not only what happened to Pittsburgh's environment, but why. What forces-economic, political, and cultural-were at work? In exploring the disturbing history of pollution in Pittsburgh, they consider not only the sooty skies, but also the poisoned rivers and creeks, the mined hills, and scarred land. Who profited and who paid for such "progress"? How did the environment Pittsburghers live in come to be, and how it can be managed for the future?In a provocative concluding essay, Samuel P. Hays explores Pittsburgh's "environmental culture," the attitudes and institutions that interpret a city's story and work to create change. Comparing Pittsburgh to other cities and regions, he exposes exaggerations of Pittsburgh's environmental achievement and challenges the community to make real progress for the future. A landmark contribution to the emerging field of urban environmental history, Devastation and Renewal will be important to all students of cities, of cultures, and of the natural world.
