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 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.
