The amount of hazardous waste in the United States has been estimated at 275 million metric tons in licensed sites alone. Is the health of Americans at risk from exposure to this toxic material? This volume, the first of several on environmental epidemiology, reviews the available evidence and makes recommendations for filling gaps in data and improving health assessments. The book explores: Whether researchers can infer health hazards from available data. The results of substantial state and federal programs on hazardous waste dangers. The book presents the results of studies of hazardous wastes in the air, water, soil, and food and examines the potential of biological markers in health risk assessment. The data and recommendations in this volume will be of immediate use to toxicologists, environmental health professionals, epidemiologists, and other biologists.

The Superfund program of the US Environmental Protection Agency (EPA) was created in the 1980s to address human-health and environmental risks posed by abandoned or uncontrolled hazardous-waste sites. Identification of Superfund sites and their remediation is an expensive multistep process. As part of this process, EPA attempts to identify parties that are responsible for the contamination and thus financially responsible for remediation. Identification of potentially responsible parties is complicated because Superfund sites can have a long history of use and involve contaminants that can have many sources. Such is often the case for mining sites that involve metal contamination; metals occur naturally in the environment, they can be contaminants in the wastes generated at or released from the sites, and they can be used in consumer products, which can degrade and release the metals back to the environment. This report examines the extent to which various sources contribute to environmental lead contamination at Superfund sites that are near lead-mining areas and focuses on sources that contribute to lead contamination at sites near the Southeast Missouri Lead Mining District. It recommends potential improvements in approaches used for assessing sources of lead contamination at or near Superfund sites.

Public health officials have the traditional responsibilities of protecting the food supply, safeguarding against communicable disease, and ensuring safe and healthful conditions for the population. Beyond this, public health today is challenged in a way that it has never been before. Starting with the 9/11 terrorist attacks, public health officers have had to spend significant amounts of time addressing the threat of terrorism to human health. Hurricane Katrina was an unprecedented disaster for the United States. During the first weeks, the enormity of the event and the sheer response needs for public health became apparent. The tragic loss of human life overshadowed the ongoing social and economic disruption in a region that was already economically depressed. Hurricane Katrina reemphasized to the public and to policy makers the importance of addressing long-term needs after a disaster. On October 20, 2005, the Institute of Medicine's Roundtable on Environmental Health Sciences, Research, and Medicine held a workshop which convened members of the scientific community to highlight the status of the recovery effort, consider the ongoing challenges in the midst of a disaster, and facilitate scientific dialogue about the impacts of Hurricane Katrina on people's health. Environmental Public Health Impacts of Disasters: Hurricane Katrina is the summary of this workshop. This report will inform the public health, first responder, and scientific communities on how the affected community can be helped in both the midterm and the near future. In addition, the report can provide guidance on how to use the information gathered about environmental health during a disaster to prepare for future events.
