 Health:

 Health Summary: Absorption is nil all routes based on physical/chemical 

properties. No significant health concerns for PMN material with a molecular weight of 1130. 

There is uncertainty about possible and lower molecular weight 

material including There are also questions about breakdown of the 

PMN material including what is generated in fires. Low concern.

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.
