In the United States, many of the millions of tons of hazardous wastes that have been produced since World War II have accumulated in sites throughout the nation. Citizen concern about the extent of this problem led Congress to establish the Superfund Program in 1980 to locate, investigate, and clean up the worst sites nationwide. Most such waste exists as a complex mixture of many substances. ...

EPA 1s deueloping an RCRA Hazardous Waste Minimlzation NatIonal Plan that will serue as the basfsfor an ouerall natlonal policy on hazardous waste management. The Plan wlll place Its hlghest prlority on source reduction, followed by recycllng. In thls article, the Chief of the EPA’s Waste Minimlzatlon Branch describes the Agency’s Draft National Plan and requests comments from readers on the is...

A dynamic discrete time model is estimated in order to analyze the evolution of perceived risk around a hazardous waste site and its effect on property values. Residential property values are modeled as a function of housing attributes and perceived risk to health from a nearby hazardous waste site using an hedonic price framework. Perceived risk enters the model as a state equation, which incl...

"This study develops a methodology that allows migration decision-making to be studied in a laboratory experimental setting. Moreover, this methodology permits an examination of the importance of natural and man-made hazards in migration decisions--factors that have not been extensively studied as determinants of migration. The specific application is to the location of the U.S. nuclear waste ...

When humans are exposed to chemicals, they are not exposed to just one chemical at a time. A vast number of chemicals pervade our environment. Exposures, whether simultaneous or sequential, are to chemical mixtures. The standard definition of a chemical mixture is any set of multiple chemicals regardless of source that may or maynot be identifiable thatmay contribute to joint toxicity in a targ...

world, and the anticipated decommissioning of facilities will generate many more drums. Currently, in compliance with federal regulations, waste storage facilities at U.S. Department of Energy (DOE) sites are inspected manually for degradation and to verify inventories. An Intelligent Mobile Sensing System (IMSS) has been developed for the automated inspection of radioactive and hazardous waste...

With the passage of the Resource Conservation and Recovery Act RCRA and the subsequent amendments to RCRA e orts to provide tighter controls on the transportation and disposal of hazardous waste have been steadily gaining ground This paper intended as a decision support tool for regional planning incorporates information on the hazardous waste generation treatment capacity and the costs of wast...

Treating hazardous-infectious medical waste can be carried out on-site or off-site of health-care establishments. Nevertheless, the selection between on-site and off-site locations for treating medical waste sometimes is a controversial subject. Currently in Iran, due to policies of Health Ministry, the hospitals have selected on-site-treating method as the preferred treatment. The objectives o...

OBJECTIVES Epidemiologic studies suggest an association between environmental exposure to benzene and hematologic cancers, but the relationship is not firmly established. The aim of this study was to assess the potential association between residence near hazardous waste sites containing benzene and hospitalization discharge rates for persons having hematologic cancers. MATERIALS AND METHODS ...
