Three acute ecotoxicity tests were conducted on an analog of PMN in 2005 by The compound tested wasand is considered an acceptable analog (by Gordon Cash) for is a liquid with an estimated boiling point is > 400 °C. The estimated vapor pressure is < 0.000001 mm Hg at 25 °C. The solubility of the is dispersible. These studies complied with OCSPP and OECD guidelines for: 1) O2, p H, temperature, water hardness values and other water quality parameters; 2) species, age, number of organisms per replicate, and biomass loading rates; and, 3) replicate and overall variability. The test was p erformed in a and there was a quality assurance statement provided.

In a 96-hour fish test, (10/ two replicate/test concentration) were exposed
to as water accommodation fraction of 6.3, 13, 25, 50, and 100 mg/L as nominal concentrations with static-renewal exposures. The test protocol was amended by aerating the test chambers throughout the 96-hour exposure period. Also, the test chambers were 25-L stainless steel containing 11.5 L of test solution rather than the or glass specified in the protocol. test solutions were mixed directly with dilution water on a weight volume basis . Each 12-L was stirred for approximately 24 hours in a 13.2 L bottle using a lined magnetic stir bar to create a vortex depth of approximately 30% of the test solution height. After mixing, the were allowed to settle for approximately one hour. The test solutions were then drawn from p laced near the bottom of the mixing vessels and added to the appropriate test chamber. The fish were transferred to newly prepared test solutions at 48 hours, and at test termination and analyzed using total was measured using a . There was no mortality in the control or 6.3

– 25 mg/L treatment groups. Mortality in the 50 and 100 mg/L treatment groups was 20 and 100%, respectively. The 96-hour LL50 for A is 62 mg/L. The 96-hour NOEL for is 25 mg/L. test is valid.

, ) were exposed to of 6.3, 13, 25, 50, and 100 mg/L with static-renewal exposures. test solutions were mixed directly with dilution water on a weight volume basis. Each was stirred for approximately 24 hours in a bottle using a lined magnetic stir bar to create a depth of approximately 30% of the test solution height. After mixing, the were allowed to settle for approximately one hour. The test solutions were then drawn from placed near the bottom of the mixing vessels and added to the appropriate test chamber. was renewed at 24 hours, and at test termination and analyzed using . was measured using a total . Observations of immobility were made at 3, 24, and 48 hours after test initiation. The 48-hour is > 100 mg/L. The of 6.3 mg/L. The test is valid.

In a 72-hour algal growth inhibition test, (1 x 104 cells/mL) were exposed to at concentrations of 1.8, 4.1, 10, 20, 45, and 100 mg/L as nominal concentrations under static conditions. The pH ranged from 7.7 to 7.9. Three replicates were used for each of the test concentrations and 6 replicates for the control. Over the course of the algal study, the temperature remained at 23.0°C. The 72-hour ErL50 (growth rate) and for are 72 and 19 mg/L, respectively. The 72-hour NOEL for was <1.8 mg/L. The 72-hour NOEL based ongrowth rate for is 1.8 mg/L. The 72-hour LOEL based on for is 1.8 mg/L. The 72-hour LOEL for growth rate for is 4.1 mg/L. The calculated geometric mean of the LOEL and NOEL (the algal chronic value or algal ChV), based on growth rate for is 2.7 mg/L. The toxicity test is valid.

All three submitted aquatic ecotoxicity studies are valid. Since is a suitable analog for , the aquatic toxicity endpoint results from can be used to assess the aquatic toxicity endpoints for . For comparative purposes, the ECOSAR (v. 1.1) p redicted fish 96-hour LC50, Daphnia 48-hour EC50 and algal 72-hour EC50 are 50, 6.1, and 4.7 mg/L for , respectively. In addition, the ECOSAR predicted chronic value for fish, daphnid and algae is 2.6, 0.52, and 1.6 mg/L. The acute concentration of concern is derived by dividing the 72-hour algal EC50 (19 mg/L or 19,000 p pb), the most sensitive aquatic species of the three submitted, by an uncertainty factor of 4 (for algae) to yield 4,750 p pb. The chronic concentration of concern is derived by dividing the predicted Daphnid ChV (0.52 mg/L), more sensitive than the experimental algal ChV of by an uncertainty factor of 10, yielding 0.052 mg/L or 52 p pb.

Acute CoC = 4,750 p pb Chronic CoC = 52 p pb
