Access Acute Exposure Guideline Levels (AEGLs) Values
On this page you will be able to access individual Acute Exposure Guideline Level (AEGLs) values that are intended to protect most individuals in the general population, including those that might be particularly susceptible to the harmful effects of the chemicals.
Find AEGL values in the table below using the chemical name or its CAS number. The AEGL values page will also have a link to the appropriate technical support document.
If only a chemical's synonym is known, it is necessary to first find that chemical's CAS number to access the AEGL entry. To find the CAS number, enter the chemical name followed by CAS in any web search engine.

AEGL Values
Final AEGLs contained in this database have been published by the National Research Council, National Academy of Sciences (NRC/NAS).
Interim AEGLs are established following review and consideration by the National Advisory Committee for AEGLs (NAC/AEGL) of public comments on Proposed AEGLs. Interim AEGLs are available for use by organizations while awaiting NRC/NAS peer review and publication of Final AEGLs. Changes to interim values and Technical Support Documents may occur prior to publication of Final AEGL values. In some cases, revised interim values may be posted on this website, but the revised Interim Technical Support Document for the chemical may be subject to change. (Further information is available through AEGL Process).
Proposed AEGLs are published in the Federal Register for public comment following review and concurrence of Draft AEGLs by the NAC/AEGL Committee. The comment period is 30 days from the date Proposed AEGLs are published in the Federal Register. (Further information is available through AEGL Process).
