A new report published by the National Academies Press (NAP) provides conclusions and recommendations for improving several acute exposure guideline level (AEGL) technical support documents. The Committee on AEGLs met in April to review the proposed AEGLs for scientific validity, completeness, internal consistency, and conformance to guidelines published by the National Research Council. The committee reviewed technical support documents for more than 20 chemicals, including acrylonitrile, cadmium, ethyl benzene, halogen fluorides, styrene, tellurium hexafluoride, thionyl chloride, and toluene.
The committee’s findings are published in the Twenty-second Interim Report of the Committee on Acute Exposure Guideline Levels, which is available as a free PDF on NAP’s website. The report is also available to view on AIHA’s website.
AEGLs are exposure levels below which adverse health effects are not likely to occur. These threshold exposure limits are for the general public and are applicable to emergency exposures ranging from 10 minutes to eight hours.
