TEST CONCENTRATIONS
- Spacing factor for test concentrations: ca. 1.8
- Range finding study
- Test concentrations:
Initial range-finding test: 0, 1.0, 10 and 100 % v/v saturated solution
Initial experiment: 0 and 10 % v/v saturated solution
Second range-finding test: 0 and 1 % v/v saturated solution
- Results used to determine the conditions for the definitive study: In the initial range-finding test, mortalities at 1.0, 10 and 100 % v/v saturated solution were 0, 0 and 100 %, respectively. In the initial experiment, 100 % mortality was seen at 10 % v/v saturated solution and in the second-range finding test, no mortality was recorded at 1 % v/v saturated solution.
Inconstancies were seen in the 10 % v/v saturated solution test concentration throughout the different tests. It was suggested by the author that this might have been due to slightly different levels of test item being in solution, as is common with a saturated solution method of preparation.
Based on this information test concentrations of 1.0, 1.8, 3.2, 5.6 and 10 % v/v saturated solution were selected for the definitive test. - Reference substance (positive control):

- Validity criteria fulfilled:
- yes
- Remarks:
- mortality in control was 0 %; semi-static test conditions; oxygen content was ≥ 60 % ASV in the control and test vessels throughout the test; results were based on measured concentrations
- Conclusions:
- Under the test conditions, the 96 h LC50 for read across substance zinc monomethacrylate to the freshwater fish rainbow trout (Oncorhynchus mykiss) was determined to be greater than 2.1 mg/L, based on the mean measured test concentrations. The No Observed Effect Concentration was 0.67 mg/L. Similar results can be expected for zinc dimethacrylate.
- Executive summary:
An acute aquatic toxicity study was performed in accordance with GLP and OECD Guideline 203. Following preliminary range-finding tests and an initial experiment, rainbow trout fish (Oncorhynchus mykiss) were exposed, in groups of seven, to an aqueous solution of the read across substance zinc monomethacrylate, over a range of concentrations of 1.0, 1.8, 3.2, 5.6 and 10 % v/v saturated solution for a period of 96 h at a temperature of 14-15 °C under semi-static test conditions. The test item solution was prepared by stirring an excess (50 mg/L) of test item in test medium using a propeller stirrer at approximately 1500 rpm for 24 h. After the stirring period any undissolved test item was removed by filtration (0.2 μm Sartorius Sartopore filter, first approximate 2 L discarded in order to pre-condition the filter) to produce a 100 % v/v saturated solution of the test item from which dilutions were prepared to give the required test concentrations. The number of mortalities and any sub-lethal effects of exposure in each test and control vessel were determined at 3, 6, 24, 48, 72 and 96 h after the start of exposure. Cumulative mortalities at 96 h were 0, 0, 0, 0, 14 and 14 % at 0, 1.0, 1.8, 3.2, 5.6 and 10 % v/v saturated solutions, respectively. Chemical analysis of the freshly prepared test media at 0 and 72 h and of the old or expired test media at 24 and 96 h showed measured test concentrations to range from 0.18 to 2.1 mg/L. Given this, it was considered appropriate to base the results on the mean measured test concentrations. Under the test conditions, the 96 h LC50 for read across substance zinc monomethacrylate to the freshwater fish rainbow trout (Oncorhynchus mykiss) was determined to be greater than 2.1 mg/L (equivalent to 0.79 mg Zn/L), based on the mean measured test concentrations. The No Observed Effect Concentration was 0.67 mg/L (Harris, 2013). Similar results can be expected for zinc dimethacrylate.

- Conclusions:
- Under the test conditions, the 96 h LC50 and NOEC values for read across substance zinc lactate to zebra fish are 100 and 56 mg/L, respectively, based on nominal concentrations. The 96 h LC50 and NOEC values for zinc cation in zinc chloride are 23.1 and 12.9 mg/L, respectively, based on measured concentration of zinc metal. Similar results can be expected for zinc dimethacrylate.
- Executive summary:
In an acute aquatic toxicity study, performed in accordance with GLP and OECD Guideline 203, groups of zebra fish (B. rerio) were exposed to read across substance zinc lactate at different concentrations for 96 h under semi-static conditions. The toxicity of read across substance zinc lactate was determined simultaneously with zinc chloride. Under the test conditions, the 96 h LC50 and NOEC values for read across substance zinc lactate to zebra fish are 100 and 56 mg/L, respectively, based on nominal concentrations. The 96 h LC50 and NOEC values for zinc cation in zinc chloride are 23.1 and 12.9 mg/L, respectively, based on measured concentration of zinc metal (Bowmer, 1998). Similar results can be expected for zinc dimethacrylate.

Additional information
An acute aquatic toxicity study was performed in accordance with GLP and OECD Guideline 203. Following preliminary range-finding tests and an initial experiment, rainbow trout fish (Oncorhynchus mykiss) were exposed, in groups of seven, to an aqueous solution of the read across substance zinc monomethacrylate, over a range of concentrations of 1.0, 1.8, 3.2, 5.6 and 10 % v/v saturated solution for a period of 96 h at a temperature of 14-15 °C under semi-static test conditions. The test item solution was prepared by stirring an excess (50 mg/L) of test item in test medium using a propeller stirrer at approximately 1500 rpm for 24 h. After the stirring period any undissolved test item was removed by filtration (0.2 μm Sartorius Sartopore filter, first approximate 2 L discarded in order to pre-condition the filter) to produce a 100 % v/v saturated solution of the test item from which dilutions were prepared to give the required test concentrations. The number of mortalities and any sub-lethal effects of exposure in each test and control vessel were determined at 3, 6, 24, 48, 72 and 96 h after the start of exposure. Cumulative mortalities at 96 h were 0, 0, 0, 0, 14 and 14 % at 0, 1.0, 1.8, 3.2, 5.6 and 10 % v/v saturated solutions, respectively. Chemical analysis of the freshly prepared test media at 0 and 72 h and of the old or expired test media at 24 and 96 h showed measured test concentrations to range from 0.18 to 2.1 mg/L. Given this, it was considered appropriate to base the results on the mean measured test concentrations. Under the test conditions, the 96 h LC50 for read across substance zinc monomethacrylate to the freshwater fish rainbow trout (Oncorhynchus mykiss) was determined to be greater than 2.1 mg/L (equivalent to 0.79 mg Zn/L), based on the mean measured test concentrations. The No Observed Effect Concentration was 0.67 mg/L (Harris, 2013). Similar results can be expected for zinc dimethacrylate.
In an acute aquatic toxicity study, performed in accordance with GLP and OECD Guideline 203, groups of zebra fish (B. rerio) were exposed to read across substance zinc lactate at different concentrations for 96 h under semi-static conditions. The toxicity of read across substance zinc lactate was determined simultaneously with zinc chloride. Under the test conditions, the 96 h LC50 and NOEC values for read across substance zinc lactate to zebra fish are 100 and 56 mg/L, respectively, based on nominal concentrations. The 96 h LC50 and NOEC values for zinc cation in zinc chloride are 23.1 and 12.9 mg/L, respectively, based on measured concentration of zinc metal (Bowmer, 1998). Similar results can be expected for zinc dimethacrylate.
In an acute aquatic toxicity study, groups (10/concentration) of arctic grayling (Thymallus arclicus) were exposed to read across substance zinc chloride for 96 h under static test system. Acute tests were run in different series:
- Series 1 (fish obtained from Alaska in 1985): One test was conducted on fry and two tests were conducted on juveniles with mean weight of 0.20 and 0.34 g
- Series 2 (fish obtained from Montana in 1986): One test was conducted on alevin and one test was conducted on juveniles with mean weight of 0.85 g
- Series 3 (fish obtained from Montana in 1988): One test was conducted on alevin and two tests were conducted on juveniles with mean weight of 0.97 and 1.85 g
Under the test conditions, the LC50 (96 h) values in different series of tests were:
- Series 1: 315 (234-424) µg/L (fry); 142 (114-178) µg/L (juvenile, 0.20 g); 112 (83-150) µg/L (juvenile, 0.34 g)
- Series 2: 1580 (900-2770) µg/L (alevin); 166 (127-217) µg/L (juvenile, 0.85 g)
- Series 3: 2920 (2510-3400) µg/L (alevin); 168 (143-197) µg/L (juvenile, 0.97 g); 168 (96-295) µg/L (juvenile, 1.85 g) (Buhl, 1990a). Similar results can be expected for zinc dimethacrylate.
In an acute aquatic toxicity study, groups (10/concentration) of coho salmon (Oncorhynchus kisutch) were exposed to read across substance zinc chloride for 96 h under static test system. Acute tests were run in different series:

- Series 2 (fish obtained from Washington in 1987): One test was conducted on alevin
Under the test conditions, the LC50 (96 h) values in different series of tests were:
