Acute Exposure Guideline Levels for Selected Airborne Chemicals

Acute Exposure Guideline Levels for Selected Airborne Chemicals, Volume 15 identifies, reviews, and interprets relevant toxicologic and other scientific data for ethyl mercaptan, methyl mercaptan, phenyl mercaptan, tert-octyl mercaptan, lewisite, methyl isothiocyanate, and selected monoisocyanates in order to develop acute exposure guideline levels (AEGLs) for these high-priority, acutely toxic chemicals.AEGLs represent threshold exposure limits (exposure levels below which adverse health effects are not likely to occur) for the general public and are applicable to emergency exposures ranging from 10 minutes (min) to 8 h. Three level-AEGL-1, AEGL-2, and AEGL-3-are developed for each of five exposure periods (10 min, 30 min, 1 h, 4 h, and 8 h) and are distinguished by varying degrees of severity of toxic effects. This report will inform planning, response, and prevention in the community, the workplace, transportation, the military, and the remediation of Superfund sites.Table of ContentsFront MatterAcute Exposure Guideline Levels for Selected Airborne Chemicals,Volume 15National Research Council Committee Review of Acute ExposureGuideline Levels of Selected Airborne ChemicalsAppendixes1 Ethyl Mercaptan Acute Exposure Guideline Levels2 Methyl Mercaptan Acute Exposure Guideline Levels3 Phenyl Mercaptan Acute Exposure Guideline Levels4 tert-Octyl Mercaptan Acute Exposure Guideline Levels5 Lewisite Acute Exposure Guideline Levels6 Methyl Isothiocyanate Acute Exposure Guideline Levels7 Selected Monoisocyanates Acute Exposure Guideline Levels
