Exposure Science in the 21st Century


Book Description

From the use of personal products to our consumption of food, water, and air, people are exposed to a wide array of agents each day-many with the potential to affect health. Exposure Science in the 21st Century: A Vision and A Strategy investigates the contact of humans or other organisms with those agents (that is, chemical, physical, and biologic stressors) and their fate in living systems. The concept of exposure science has been instrumental in helping us understand how stressors affect human and ecosystem health, and in efforts to prevent or reduce contact with harmful stressors. In this way exposure science has played an integral role in many areas of environmental health, and can help meet growing needs in environmental regulation, urban and ecosystem planning, and disaster management. Exposure Science in the 21st Century: A Vision and A Strategy explains that there are increasing demands for exposure science information, for example to meet needs for data on the thousands of chemicals introduced into the market each year, and to better understand the health effects of prolonged low-level exposure to stressors. Recent advances in tools and technologies-including sensor systems, analytic methods, molecular technologies, computational tools, and bioinformatics-have provided the potential for more accurate and comprehensive exposure science data than ever before. This report also provides a roadmap to take advantage of the technologic innovations and strategic collaborations to move exposure science into the future.




Air Pollution in the 21st Century


Book Description

This symposium was jointly organized by the United States Environmental Protection Agency and The Netherlands Ministry of Housing, Spatial Planning and the Environment. These proceedings will provide a stimulus for taking up the challenges of environmental policy development in the 21st century, and will contribute to continuing co-operation.Clean air is a basic condition for health. Air pollution aggravates respiratory problems, leading to increased sickness absenteeism, increased use of health care services and even premature mortality. Air pollution is under intensive discussion in the United States and Europe.In The Netherlands, a wide range of policy instruments have been formulated which have reduced air pollution. For example; since 1975, sulphur dioxide and lead emissions have been reduced. However, emission reduction figures for many other substances are more modest. Many air pollution problems persist because progress in countering these problems is nullified by growth in the economy and traffic. Another important target is the prevention of climate change. The international community is agreed that the increasing concentration of greenhouse gases in the atmosphere has led to a gradual increase in the earth's temperature. In terms of the environmental consequences and social implications, the greenhouse problem surpasses all other air quality problems.Across Europe, strategies are being developed to reduce acidification and photochemical air pollution. An air emission ceiling for each country in the European Union is being agreed. In the area of climate change, there is good co-operation between the United States, The Netherlands and other EU Members States in the ongoing global negotiations. This is the start of a new movement. In the last century economies and societies developed through increasing human productivity. In the next century they must develop through increasing the productivity of fuel and natural resources.




Toxicity Testing in the 21st Century


Book Description

Advances in molecular biology and toxicology are paving the way for major improvements in the evaluation of the hazards posed by the large number of chemicals found at low levels in the environment. The National Research Council was asked by the U.S. Environmental Protection Agency to review the state of the science and create a far-reaching vision for the future of toxicity testing. The book finds that developing, improving, and validating new laboratory tools based on recent scientific advances could significantly improve our ability to understand the hazards and risks posed by chemicals. This new knowledge would lead to much more informed environmental regulations and dramatically reduce the need for animal testing because the new tests would be based on human cells and cell components. Substantial scientific efforts and resources will be required to leverage these new technologies to realize the vision, but the result will be a more efficient, informative and less costly system for assessing the hazards posed by industrial chemicals and pesticides.




Science for Environmental Protection


Book Description

In anticipation of future environmental science and engineering challenges and technologic advances, EPA asked the National Research Council (NRC) to assess the overall capabilities of the agency to develop, obtain, and use the best available scientific and technologic information and tools to meet persistent, emerging, and future mission challenges and opportunities. Although the committee cannot predict with certainty what new environmental problems EPA will face in the next 10 years or more, it worked to identify some of the common drivers and common characteristics of problems that are likely to occur. Tensions inherent to the structure of EPA's work contribute to the current and persistent challenges faced by the agency, and meeting those challenges will require development of leading-edge scientific methods, tools, and technologies, and a more deliberate approach to systems thinking and interdisciplinary science. Science for Environmental Protection: The Road Ahead outlines a framework for building science for environmental protection in the 21st century and identified key areas where enhanced leadership and capacity can strengthen the agency's abilities to address current and emerging environmental challenges as well as take advantage of new tools and technologies to address them. The foundation of EPA science is strong, but the agency needs to continue to address numerous present and future challenges if it is to maintain its science leadership and meet its expanding mandates.




Science and Decisions


Book Description

Risk assessment has become a dominant public policy tool for making choices, based on limited resources, to protect public health and the environment. It has been instrumental to the mission of the U.S. Environmental Protection Agency (EPA) as well as other federal agencies in evaluating public health concerns, informing regulatory and technological decisions, prioritizing research needs and funding, and in developing approaches for cost-benefit analysis. However, risk assessment is at a crossroads. Despite advances in the field, risk assessment faces a number of significant challenges including lengthy delays in making complex decisions; lack of data leading to significant uncertainty in risk assessments; and many chemicals in the marketplace that have not been evaluated and emerging agents requiring assessment. Science and Decisions makes practical scientific and technical recommendations to address these challenges. This book is a complement to the widely used 1983 National Academies book, Risk Assessment in the Federal Government (also known as the Red Book). The earlier book established a framework for the concepts and conduct of risk assessment that has been adopted by numerous expert committees, regulatory agencies, and public health institutions. The new book embeds these concepts within a broader framework for risk-based decision-making. Together, these are essential references for those working in the regulatory and public health fields.




Identifying and Reducing Environmental Health Risks of Chemicals in Our Society


Book Description

"On November 7-8, 2013, the Institute of Medicine's Roundtable on Environmental Health Sciences, Research, and Medicine held a workshop to discuss approaches related to identifying and reducing potential environmental public health risks to new and existing industrial chemicals present in society. Industrial chemicals include chemicals used in industrial processes or commercial products, not including those found in food, pesticides, or pharmaceuticals. Identifying and Reducing Environmental Health Risks of Chemicals in Our Society is a summary and synthesis of the presentations and discussions that took place during the two days of the workshop. The workshop examined successes and areas for improvement within current regulatory programs for assessing industrial chemical safety, frameworks for chemical prioritization to inform targeted testing and risk management strategies, concepts of sustainability and green chemistry that support the design and use of safer alternatives, and efforts to reduce the risk of chemicals in our society."--Publisher's description.




A Research Strategy for Environmental, Health, and Safety Aspects of Engineered Nanomaterials


Book Description

The nanotechnology sector, which generated about $225 billion in product sales in 2009, is predicted to expand rapidly over the next decade with the development of new technologies that have new capabilities. The increasing production and use of engineered nanomaterials (ENMs) may lead to greater exposures of workers, consumers, and the environment, and the unique scale-specific and novel properties of the materials raise questions about their potential effects on human health and the environment. Over the last decade, government agencies, academic institutions, industry, and others have conducted many assessments of the environmental, health, and safety (EHS) aspects of nanotechnology. The results of those efforts have helped to direct research on the EHS aspects of ENMs. However, despite the progress in assessing research needs and despite the research that has been funded and conducted, developers, regulators, and consumers of nanotechnology-enabled products remain uncertain about the types and quantities of nanomaterials in commerce or in development, their possible applications, and their associated risks. A Research Strategy for Environmental, Health, and Safety Aspects of Engineered Nanomaterials presents a strategic approach for developing the science and research infrastructure needed to address uncertainties regarding the potential EHS risks of ENMs. The report summarizes the current state of the science and high-priority data gaps on the potential EHS risks posed by ENMs and describes the fundamental tools and approaches needed to pursue an EHS risk research strategy. The report also presents a proposed research agenda, short-term and long-term research priorities, and estimates of needed resources and concludes by focusing on implementation of the research strategy and evaluation of its progress, elements that the committee considered integral to its charge.




Exposure


Book Description

“For Erin Brockovich fans, a David vs. Goliath tale with a twist” (The New York Times Book Review)—the incredible true story of the lawyer who spent two decades building a case against DuPont for its use of the hazardous chemical PFOA, uncovering the worst case of environmental contamination in history—affecting virtually every person on the planet—and the conspiracy that kept it a secret for sixty years. The story that inspired Dark Waters, the major motion picture from Focus Features starring Mark Ruffalo and Anne Hathaway, directed by Todd Haynes. 1998: Rob Bilott is a young lawyer specializing in helping big corporations stay on the right side of environmental laws and regulations. Then he gets a phone call from a West Virginia farmer named Earl Tennant, who is convinced the creek on his property is being poisoned by runoff from a neighboring DuPont landfill, causing his cattle and the surrounding wildlife to die in hideous ways. Earl hasn’t even been able to get a water sample tested by any state or federal regulatory agency or find a local lawyer willing to take the case. As soon as they hear the name DuPont—the area’s largest employer—they shut him down. Once Rob sees the thick, foamy water that bubbles into the creek, the gruesome effects it seems to have on livestock, and the disturbing frequency of cancer and other health problems in the area, he’s persuaded to fight against the type of corporation his firm routinely represents. After intense legal wrangling, Rob ultimately gains access to hundreds of thousands of pages of DuPont documents, some of them fifty years old, that reveal the company has been holding onto decades of studies proving the harmful effects of a chemical called PFOA, used in making Teflon. PFOA is often called a “forever chemical,” because once in the environment, it does not break down or degrade for millions of years, contaminating the planet forever. The case of one farmer soon spawns a class action suit on behalf of seventy thousand residents—and the shocking realization that virtually every person on the planet has been exposed to PFOA and carries the chemical in his or her blood. What emerges is a riveting legal drama “in the grand tradition of Jonathan Harr’s A Civil Action” (Booklist, starred review) about malice and manipulation, the failings of environmental regulation; and one lawyer’s twenty-year struggle to expose the truth about this previously unknown—and still unregulated—chemical that we all have inside us.




Environmental Change and Globalization: Double Exposures


Book Description

This book explores the connections between two of the most transformative processes of the twenty-first century, namely climate change and globalization. In this book, Leichenko and O'Brien present a conceptual framework for analyzing the interactions between these two processes, and illustrate, through case studies, how these interactions create situations of "double exposure." Drawing upon prominent recent and current climate-related events -- Hurricane Katrina in New Orleans, recurring droughts in India, and the melting of Arctic sea ice -- the case studies each demonstrate a different pathway of interaction between globalization and global environmental change. Through exploration of these pathways of double exposure, the book also shows how broader human security concerns including growing inequalities, growing vulnerabilities, and unsustainable rates of development are integrally connected to both processes of global change. The double exposure framework not only sheds light on the challenges raised by these two global processes, but also reveals possibilities for using the interactions to generate positive opportunities for action.




Educational Research and Innovation Educating 21st Century Children Emotional Well-Being in the Digital Age


Book Description

What is the nature of childhood today? On a number of measures, modern children's lives have clearly improved thanks to better public safety and support for their physical and mental health. New technologies help children to learn, socialise and unwind, and older, better-educated parents are increasingly playing an active role in their children's education. At the same time, we are more connected than ever before, and many children have access to tablets and smartphones before they learn to walk and talk. Twenty-first century children are more likely to be only children, increasingly pushed to do more by "helicopter parents" who hover over their children to protect them from potential harm. In addition to limitless online opportunities, the omnipresent nature of the digital world brings new risks, like cyber-bullying, that follow children from the schoolyard into their homes. This report examines modern childhood, looking specifically at the intersection between emotional well-being and new technologies. It explores how parenting and friendships have changed in the digital age. It examines children as digital citizens, and how best to take advantage of online opportunities while minimising the risks. The volume ends with a look at how to foster digital literacy and resilience, highlighting the role of partnerships, policy and protection.
