 Health:

 Health Summary: Absorption is poor all routes based on analogs. There is 

concern for lung overload if inhaled based on poorly soluble particulates and nano sized 

materials. There is also concern for oncogenicity if inhaled and based on the nano size of the 

PMN material. Uncertain concern for mutagenicity and immunotoxicity.

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. 

Remarks: This is a bounding “what if” scenario assuming 0% removal in wastewater treatment, 0% 

destruction in incineration, rapid migration to groundwater, BCF = 5,000, and COC = 1ppb.
