Book Description
The technical basis of environmental regulation is always at the edge of scientific and engineering understanding. As knowledge improves, questions will inevitably arise about past decisions. Understanding how the regulatory system accommodates changing scientific and engineering knowledge is vital for achieving environmental values. In this new volume, seven case studies shed light on the interplay between environmental regulation and scientific and engineering understanding, with practical conclusions on how science and engineering should be used for more sound and timely regulatory decision making. The book provides helpful timelines of scientific and regulatory developments for the cases, which include: Factors impeding clean-up strategies in the Chesapeake Bay. Pivotal questions in the regulation of ambient ozone concentrations. How science has been heeded but also ignored in regulation of new municipal waste combustors. Impact of scientific findings on control of chlorination by-products. Acid rain and what can be learned about research and public policy debate. Controversy over the need for formaldehyde regulation. The effect of public perception on management decisions concerning dioxin. This volume will be of practical interest to policymakers, business and environmental advocates, scientists, engineers, researchers, attorneys, faculty, and students.

Pages : 578
Book Description
Written by an outstanding group of contributors, this book examines the function and structure of coastal lagoonal ecosystems and the natural and anthropogenic drivers of change that affect them, most notably nutrient over-enrichment from coastal watersheds and airsheds. The contributors target the susceptibility of coastal lagoons to eutrophication, the indicators of eutrophic conditions, the influences of natural factors such as major storms and other climate effects, and the resulting biotic and ecosystem impairments that have developed. The book compares biogeochemical and ecological response to nutrient enrichment and other pollutants in lagoonal estuaries to those in other estuarine types.

Book Description
That one could “walk drishod on the backs” of schools of salmon, shad, and other fishes moving up Atlantic coast rivers was a not uncommon kind of description of their migratory runs during early Colonial times. Accounts tell of awe-inspiring numbers of spawners pushing their way upriver, the waters “running silver,” to complete life cycles that once replenished critical marine fisheries along the Eastern Seaboard. This is a hugely important, fascinating, and unique look at the fish of North America whose history and life-cycles and conservation challenges are poorly understood. Despite these primordial abundances, over the centuries these stocks were so stressed that virtually all are now severely depressed, with many biologically or commercially extinct and some simply forgotten. Running Silver will tell the story of the past, present and future of these sea-river fish. This important book will elevate public consciousness of the contrasts between the historical and the present to show the enormous legacy that has already been lost and to help inspire efforts to save what remains. Drawing on the author's thirty-year career as a scientist and educator with a passion for the native river fish of the North East, Running Silver tells the story of these endangered fish with a mix of research, historical accounts, anecdotes, personal experience, interviews, and images.
