 Health:

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

Michael addition to the acrylate. There is concern for mutagenicity, oncogenicity, dermal and 

respiratory sensitization, developmental toxicity, irritation, and liver and kidney effects for the 

acrylate. There is also concern for liver effects and developmental toxicity for the 

moiety. The concern for oncogenicity for is 

not thought to be relevant to humans. is negative in Salmonella but is positive in 

the mouse lymphoma assay and is positive for unscheduled DNA synthesis (UDS) in rats. Low 

moderate 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.
