- guideline study
- Remarks:
- Study conducted to recent EU test guidance in compliance with GLP and reported with a GLP certificate. This study is read across to the Structural Analogue 02, which is considered to be structurally equivalent to the substance to be registered, in that only the halogen ion differs structurally (fluorine instead of chlorine). The Structural Analogue 02 also contains a form where hydroxyl group replaces the chlorine. Neither of these differing analogues are considered to adversely affect the toxicity or intrinsic effects overall between the molecules. Details of structure are detailed below under "illustrations”.

- Details on test conditions:
- The study was conducted in a static system. The test chambers, which were calibrated to 4 liters, were made of glass (length 20 cm, width 15 cm, height 20 cm) and stood in a water bath made of Hostalit Z® with a Plexiglas viewing panel. The temperature of the water bath was regulated by a thermostat to 22 + 1 °C. The chambers were illuminated from above from 06.00 a.m to 06.00 p.m. The light intensity directly over the chambers was approximately 700 lux.
The test chambers were not aerated during the course of the study.
After the test concentrations had been prepared and water parameters recorded, 7 fish were assigned to each test and control chamber. The fish received no feed for the entire study period. Inspection of the fish took place after 3, 6, 24, 48, 72 and 96 hours and involved recording the lethality and visible changes in appearance and behavior. Dead fish were removed from the chambers. Fish were considered dead when there was a lack of opercular movement and no response to slight mechanical stimulus. The water parameters were measured and recorded before study start and after 0, 24, 48, 72 and 96 hours. - Reference substance (positive control):

- The study was conducted in a static system. The test chambers, which were calibrated to 10 liters, were made of glass (length 30 cm, width 22 cm, height 24 cm) and stood in a water bath made of Hostalit with a Plexiglas viewing panel. The temperature of the water bath was regulated by a thermostat to 22 ±1°C. The chambers were illuminated above 12 hours. The light intensity directly over the chambers was
approximately 700 lux. The test chambers were not aerated during the course of the study.
Reconstituted water, composition according to ISO/DIS 7346/1 was used as water for dilution.
Preparation was carried out in a unit consisting of two Hostalen- lined steel vessels with a capacity of 1700 Iitres each.
The dilution water was prepared as described and was aerated until oxygen saturation.
The pH was measured before the use of each study batch. It was in a range of 7.9 - 8.1.
After the test concentrations had been prepared and water parameters recorded, 10 fish were assigned to each test and control chamber. The fish received no feed for the entire study period. Inspection of the fish took place after 2 - 4, 24, 48, 72 and 96 hours and involved recording the lethality and visible changes in appearance and behavior. Dead fish were removed from the chambers. Fish were considered dead when there was a lack of opercular movement and no response to slight mechanical stimulus. The water parameters were measured and recorded before study start and after 0, 2 - 4, 24, 48, 72 and 96 hours. - Duration:

- Details on results:
- Because of the colouration of the test solutions the observation of symptoms was disturbed in the 710 and 1000 mg/L groups, The fish showed changes in behavior, swimming behavior and partly in respiration rate in the 500,710 and 1000 mg/L groups.
Symptoms occurred during the entire exposure time. The 100 mg/L group showed no effect in comparison with the negative control.
Dead fish showed redded opercula, lock-jaw, partly dark or yellow or light coloured integument. - Reported statistics and error estimates:
- Probit analysis could not be carried out after 24, 48 and 72 hours because of the lethality rate. As the factor for the concentration steps was 1.41 (2nd root of 10) no further concentrations were tested. After 48 hours the geometric mean of the LC0 and LC100 and after 24 and 72 hours the LC50 range are given.
On the basis of the lethality rate, the LC50 values were determined after 96 hours by means of the probit analysis. - Validity criteria fulfilled:
- yes
- Conclusions:
- The LC50 after 96 hours was 596 mg/L under the conditions of this test
- Executive summary:
The acute toxicity of the test substance in zebra fish was determined in a study over 96 hours. The concentrations tested were 100, 500, 710 and 1000 mg/L and a negative control (0 mg/L).
The test batches were present as orange to dark red solutions. No particulate matter was observed. The substance concentration was determined in all test batches. All values determined were in a range of ±20% of the theoretical value.
In this 96-hour acute toxicity study in zebra fish (Brachydanio rerio) over 96 hours the following lethality values were determined:
24 h 48 h 72 h 96 h LC0 [mg/L] 1000 710 500 100 LC50 [mg/L] > 1000 842.6 710 - 1000 596 (CI: 525 - 675) LC1000 [mg/L] not determined 1000 1000 1000 Symptoms and lethality were observed at 500, 710 and 1000 mg/L. The 100 mg/L group showed no symptoms and no lethality.
