At the request of the Department of Defense and the Environmental Protection Agency, the National Research Council has reviewed the relevant scientific literature compiled by an expert panel and established Acute Exposure Guideline Levels (AEGLs) for several chemicals. AEGLs represent ...

Extremely hazardous substances (EHSs)² can be released accidentally as a result of chemical spills, industrial explosions, fires, or accidents involving railroad cars and trucks transporting EHSs. Workers and residents in communities surrounding industrial facilities where EHSs are manufactured, used, or ...

At the U.S. Army's request the National Research Council (NRC) established the Committee to Review Risk Assessment Approaches for the Medical Countermeasures Test and Evaluation (MCMT&E) facility at Fort Detrick, in Frederick, Maryland. The committee was charged with reviewing a ...

The indoor environment affects occupants' health and comfort. Poor environmental conditions and indoor contaminants are estimated to cost the U.S. economy tens of billions of dollars a year in exacerbation of illnesses like asthma, allergic symptoms, and subsequent lost productivity. ...

Extremely hazardous substances (EHSs) can be released accidentally as a result of chemical spills, industrial explosions, fires, or accidents involving railroad cars or trucks transporting EHSs. They can also be released intentionally through terrorist activities, or inadvertently by improper storage ...

Exposure to high-priority, acutely toxic chemicals for prolonged periods can potentially manifest into adverse health effects and deadly outcomes. Thus, to identify, review, and interpret relevant toxicological and other scientific data and to develop acute exposure guideline levels (AEGLs), the ...

Formaldehyde is ubiquitous in indoor and outdoor air, and everyone is exposed to formaldehyde at some concentration daily. Formaldehyde is used to produce a wide array of products, particularly building materials; it is emitted from many sources, including power plants, ...

The U.S. Army Medical Research and Materiel Command plans to construct and operate a new Medical Countermeasures Test and Evaluation facility at Fort Detrick in Frederick, Maryland. The facility is intended to handle infectious agents that require safety precautions ...

The present report is the committee's 19th interim report. It summarizes the committee's conclusions and recommendations for improving NAC's AEGL documents for the following chemicals and chemical classes: acrylonitrile, benzonitrile, boron tribromide, BZ (3-quinuclidinyl benzilate), chloroarsenicals, chloroformates, bis-chloromethylether, chloromethylether, chlorosilanes ...
