1 Exposure scenario titles consist of release activity followed by exposure calculation abbreviation. 

2 Release activities are from engineering report's Manufacturing (Mfg), Processing (Proc) and Use release 

activity labels. 

 Multiple release activities are combined in one exposure scenario if their releases occur at same location. 

3 Exposure calculations are Acute Dose Rate (ADR), Lifetime Average Daily Dose (LADD), and 

Probabilistic Dilution Model (PDM). There may be one, two, or all three exposure calculations per exposure 

scenario. CC is the aquatic concentration of concern. 

4 This column displays concentration values for the 7Q10 streamflow, which is defined as the average daily 

streamflow of the seven consecutive days of lowest flow within a ten year period.

hours that occurs no more frequently than monthly) is to treat such events as independent, acute exposures rather than 

as chronic exposure. (Methods for Exposure-Response Analysis for Acute Inhalation Exposure to Chemicals (External 

Review Draft). EPA/600/R-98/051. April 1998)

1 Exposure scenario titles consist of release activity followed by exposure calculation abbreviation. 

2 Release activities are from engineering report's Manufacturing (Mfg), Processing (Proc) and Use release 

activity labels. Multiple release activities are combined in one exposure scenario if their releases occur at 

same location. 

3 Exposure calculations are Acute Dose Rate (ADR), Lifetime Average Daily Dose (LADD), and 

Probabilistic Dilution Model (PDM). There may be one, two, or all three exposure calculations per exposure 

scenario. CC is the aquatic concentration of concern. 

4 This column displays concentration values for the 7Q10 streamflow, which is defined as the average daily 

streamflow of the seven consecutive days of lowest flow within a ten year period.

Note: The general Agency guidance for assessing short-term, infrequent events (for most chemicals, an exposure of less than 24 

hours that occurs no more frequently than monthly) is to treat such events as independent, acute exposures rather than 

as chronic exposure. (Methods for Exposure-Response Analysis for Acute Inhalation Exposure to Chemicals (External 

Review Draft). EPA/600/R-98/051. April 1998)
