AEGL

Acute Exposure Guideline Levels. AEGL values represent toxicologically substantiated ceiling exposure levels for different relevant exposure periods (10 minutes, 30 minutes, 1 hour, 4 hours, 8 hours), for three different degrees of severity of toxic effects: AEGL-1: threshold for notable discomfort; AEGL-2: threshold for serious, long-lasting effects or an impaired ability to escape; AEGL-3: threshold for lethal effects. AEGL values take into account the general population, including susceptible individuals.
