Health : Health Summary: Absorption is moderate all routes based on p hysical/chemical properties. There is concern for mutagenicity are positive in the lymphoma assay and sometimes in chromosome aberrations assays), irritation, and dermal and respiratory sensitization based on the moiety. Low moderate concern. Test Data: negative in Salmonella and E coli moderate skin irritant acute oral study in rats - no deaths or signs of toxicity at 2000 mg/kg

1 Exposure scenario titles consist of release activity followed by exposure calculation abbreviation. 2 Release activities are from engineering report's Manuf acturing (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 (A DR), 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 7Q 10 streamflow, which is defined as the average daily streamflow of the seven consecutive days of lowest flow within a ten year period.

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 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.
