Definitions for "EMEG"
nvironmental edia valuation uide, a media-specific comparison value that is used to select contaminants of concern. Levels below the EMEG are not expected to cause adverse noncarcinogenic health effects. These have been developed for acute exposure scenarios (EMEG-a), intermediate exposure scenarios (EMEG-i), and chronic exposure scenarios (EMEG-c).
Environmental Media Evaluation Guides. A concentration of a contaminant in water, soil, or air that is unlikely to be associated with any appreciable risk of deleterious noncancer effects over a specified duration of exposure. EMEGs are derived from ATSDR Minimal Risk Levels by factoring in default body weights and ingestion rates. Separate EMEGs are computed for acute ( 14 days), intermediate (15-364 days), and chronic (365 days) exposures.
a concentration of a chemical in soil, air, or water, above which a person might experience adverse health if exposed to that chemical
