Chlorination in various forms has been the predominant method of drinking water disinfection in the United States for more than 70 years. The seventh volume of the Drinking Water and Health series addresses current methods of drinking water disinfection and compares standard chlorination techniques with alternative methods. Currently used techniques are discussed in terms of their chemical activity, and their efficacy against waterborne pathogens, including bacteria, cysts, and viruses, is compared. Charts, tables, graphs, and case studies are used to analyze the effectiveness of chlorination, chloramination, and ozonation as disinfectant processes and to compare these methods for their production of toxic by-products. Epidemiological case studies on the toxicological effects of chemical by-products in drinking water are also presented.

The US Environmotection Agency Office of Radiation and Indoor Air asked the National Research Council to evaluate whether sufficient new data exist to warrant a reassessment of health risks reported in Health Effects of Exposure to Low Levels of Ionizing Radiations (BEIR V) in 1990. To respond to this request, the National Research Council assembled the Committee on Health Risks of Exposure to Low Levels of Ionizing Radiations. The work of the committee was conducted in what was called the BEIR VII phase-1 study. To assist the committee during its deliberations, various scientists were consulted for advice, and a workshop on the impact of biology on risk assessment was held in collaboration with the Department of Energy Office of Health and Environmental Research. The intent of the workshop was to address the implications of new understanding of the biologic basis of radiation injury and carcinogenesis for risk assessment.

Compensating for Wetland Losses Under the Clean Water Act
AvNational Research Council,Division on Earth and Life Studiesm. fl.
Inbunden, Engelska, 2001
856 kr
Skickas
Recognizing the importance of wetland protection, the Bush administration in 1988 endorsed the goal of a /no net lossa of wetlands. Specifically, it directed that filling of wetlands should be avoided, and minimized when it cannot be avoided. When filling is permitted, compensatory mitigation must be undertaken; that is, wetlands must be restored, created, enhanced, and, in exceptional cases, preserved, to replace the permitted loss of wetland area and function, such as water quality improvement within the watershed. After more than a dozen years, the national commitment to a /no net lossa of wetlands has been evaluated. This new book explores the adequacy of science and technology for replacing wetland function and the effectiveness of the federal program of compensatory mitigation in accomplishing the nationa (TM)s goal of clean water. It examines the regulatory framework for permitting wetland filling and requiring mitigation, compares the mitigation institutions that are in use, and addresses the problems that agencies face in ensuring sustainability of mitigated wetlands over the long term.Gleaning lessons from the mixed results of mitigation efforts to date, the book offers 10 practical guidelines for establishing and monitoring mitigated wetlands. It also recommends that federal, state, and local agencies undertake specific institutional reforms. This book will be important to anyone seeking a comprehensive understanding of the a /no net lossa issue: policy makers, regulators, environmental scientists, educators, and wetland advocates.

In this century, the United States will be challenged to provide sufficient quantities of high-quality water to its growing population. Water is a limiting resource for human well-being and social development, and projections of population growth as well as changing social values suggest that demands for this resource will increase significantly. These projections have fueled concerns among the public and water resources professionals alike about the adequacy of future water supplies, the sustainability and restoration of aquatic ecosystems, and the viability of our current water resource research programs and our institutional and physical water resource infrastructures.With the goal of outlining a roadmap to guide policymakers, the Water Science and Technology Board (WSTB) held a series of discussions at several of its meetings in 1998-2000 about the future of the nation's water resources and the appropriate research needed to achieve their long-term sustainability. From those discussions, the board produced this report, the objectives of which are to:draw attention to the urgency and complexity of water resources issues facing the United States in the twenty-first century;broadly inform decision makers, researchers, and the public about these issues and challenges;identify needed knowledge and corresponding water resources research areas that should be emphasized immediately and over the long term; anddescribe ways in which the setting of the water research agenda, the conduct of water research, and investments devoted to such research should be improved in the next few decades.This report discusses major research questions related to the critical water issues that face the nation. It lays out an interdisciplinary research portfolio for the next 20 years and recommends agenda-setting processes that can maximize the nation's ability to prioritize and conduct water resources research.

According to surveys, the public believes the chickens it is buying are wholesome. Poultry Inspection: The Basis for a Risk-Assessment Approach looks at current inspection procedures to determine how effective the Food Safety Inspection Service is in finding dangerous levels of contaminants and disease-producing microorganisms. The book first describes the history behind the current system, noting that the amount of poultry inspected has increased dramatically while techniques and regulations have remained constant since 1968. The steps involved in an inspection are then described, followed by a discussion of alternative and innovative inspection procedures. It then provides a risk-assessment model for poultry, including submodels for each stage of processing. Risk assessment is used to protect health, establish priorities, identify problems, and set acceptable levels of risk. The model is applied both to microbiological hazards and to chemical contaminants.
Riparian Areas
Functions and Strategies for Management

The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasa "the lands bordering rivers and lakesa "even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along Americaa (TM)s waterbodies should be a national goal.

The Missouri River Ecosystem: Exploring the Prospects for Recovery resulted from a study conducted at the request of the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers. The nationa (TM)s longest river, the Missouri River and its floodplain ecosystem experienced substantial environmental and hydrologic changes during the twentieth century. The context of Missouri River dam and reservoir system management is marked by sharp differences between stakeholders regarding the rivera (TM)s proper management regime. The management agencies have been challenged to determine the appropriate balance between these competing interests. This Water Science and Technology Board report reviews the ecological state of the river and floodplain ecosystem, scientific research of the ecosystem, and the prospects for implementing an adaptive management approach, all with a view toward helping move beyond ongoing scientific and other differences. The report notes that continued ecological degradation of the ecosystem is certain unless some portion of pre-settlement river flows and processes were restored.The report also includes recommendations to enhance scientific knowledge through carefully planned and monitored river management actions and the enactment of a Missouri River Protection and Recovery Act.

People spend the vast majority of their time inside their homes and other indoor environments where they are exposed to a wide range of chemicals from building materials, furnishings, occupants, cooking, consumer products, and other sources. Despite research to date, very little is known about how exposures to indoor chemicals across complex chemical phases and pathways affect human health. The COVID-19 pandemic has only increased public awareness of indoor environments and shed light on the many outstanding questions about how best to manage chemicals indoors. This report identifies gaps in current research and understanding of indoor chemistry and new approaches that can be applied to measure, manage, and limit chemical exposures. Why Indoor Chemistry Matters calls for further research about the chemical transformations that can occur indoors, pathways and timing of indoor chemical exposure, and the cumulative and long-term impacts of exposure on human health. Research priorities should consider factors that contribute to measurable environmental health disparities that affect vulnerable populations, such as the age, location, and condition of buildings that can alter exposures to indoor chemicals.
Biosolids Applied to Land

Skickas
The 1993 regulation (Part 503 Rule) governing the land application of biosolids was established to protect public health and the environment from reasonably anticipated adverse effects. Included in the regulation are chemical pollutant limits, operational standards designed to reduce pathogens and the attraction of disease vectors, and management practices. This report from the Board on Environmental Studies and Toxicology evaluates the technical methods and approaches used by EPA to establish those standards and practices, focusing specifically on human health protection. The report examines improvements in risk-assessment practices and advances in the scientific database since promulgation of the regulation, and makes recommendations for addressing public health concerns, uncertainties, and data gaps about the technical basis of the biosolids standards.
Assessment of Proposed Partnerships to Implement a National Landslide Hazards Mitigation Strategy
Interim Report

Skickas
Landslides are a component of those agents of nature that transport rock and soil from mountains or hillsides to streams, lakes and seas, where new sedimentary rocks begin to form. Therefore, as well as destructive forces that can be induced by human activity, landslides are part of the earth's natural cyclic process of uplift, erosion, and sedimentation. With the growth of human population and the increasing habitation of ever-steeper slopes and higher altitudes, Man is both experiencing the effects of landslides and causing landslides with increasing frequency. These adverse effects include loss of life, injury, and damage to public and private works, as well as environmental damage. Accordingly, it is an opportune time to address the hazard posed by landslides, and to assess strategies to mitigate that hazard. Assessment of Proposed Partnerships to Implement a National Landslide Hazards Mitigation Strategy: Interim Reports is an interim statement addressing the U.S. Geological Survey's proposal for a national landslide hazards mitigation strategy.The scope of this interim report is constrained to assessing whether all the partners necessary for such a national strategy have been identified by the proposal-conclusions and recommendations to address the remainder of the statement of task will be presented in the committee's final report (e.g., will include comments regarding effective partnership implementation; funding strategies required for an effective mitigation program; and the balance between different components of a national strategy). In addition, in this interim report the committee offers a number of comments intended as interim guidance for the U.S. Geological Survey as it continues to plan a national strategy.
