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 Manufact uring (Mfg), Processing (Proc) and Use release activity labels. Multiple release activities are combined in one expo sure 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 calculati ons 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, ra pid migration to groundwater, BCF = 5,000, and COC = 1ppb.6/21/2011 Page of
