High-End Exposure (Dose) Estimate
High-End Exposure (Dose) Estimate : (a) A plausible estimate of individual exposure or dose for those persons at the upper end of an exposure or dose distribution, conceptually above the 90th percentile, but not higher than the individual in the population who has the highest exposure or dose. [USEPA, 1992: GL for Exposure Assessment] [REAP, 1995: Residential Exposure Assessment Project]; (b) An estimate of exposure, or dose level received anyone in a defined population that is greater than the 90th percentile of all individuals in that population, but less than the exposure at the highest percentile in that population. A high end risk descriptor is an estimate of the risk level for such individuals. Note that risk is based on a combination of exposure and susceptibility to the stressor.
