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
a contaminant concentration in water, soil, or air at which daily human exposure is unlikely to result in adverse noncancerous effects
an estimate of daily human exposure to a chemical (in mg/kg/day) that is likely to be without noncarcinogenic health effects over a specified duration of exposure
ATSDR's environmental media guide
ATSDR environmental media evaluation guide
Environmental media evaluation guide. A concentration in air, soil, or water below which adverse noncancer health effects are not expected to occur. The EMEG is a comparison value used to select contaminants of potential health concern and is based on ATSDR's minimal risk level (MRL).
Environmental Media Evaluation Guide (see definition in next section)
Environmental Media Evaluation Guide--is derived from the ATSDR's Minimal Risk Level (MRL) using standard exposure assumptions, such as ingestion of 2 liters of water per day and body weight of 70 kg for adults. MRL's are estimates of daily human exposure to a chemical likely to be without an appreciable risk of noncancerous illnesses, generally for a year or longer.
