Evaluation of Airborne Exposure Limits for G-Agents: Occupational and GeneralPopulation Exposure Criteria

摘要

Existing occupational airborne exposure limits (now referred to as workerpopulation limits or WPLs) and general population airborne exposure limits (now referred to as general population limits or GPLs) were reviewed and recalculated using current risk assessment methods and incorporation of data not considered in previous estimates. The existing WPLs for agents GB (0.0001 mg/cu m), GA (0.0001 mg/cu m) and GD (0.00003 mg/cu m) were deemed adequately protective. Similarly, GPL values were recalculated and found to be adequately protective for GB (0.000003 mg/cu m), and GA (0.000003 mg/cu m). A GPL value of (0.000001 mg/cu m) was recommended for GD. New WPL (0.00003 mg/cu m), and GPL (0.000001 mg/cu m) exposure guidelines were developed for GF, for which none previously existed. The existing acute exposure guidelines for occupational workers, namely those for Immediately Dangerous to Life or Health, Short-Term Exposure Limits, and Acute Exposure Guideline Levels, were recalculated and are described in this report.
