Sampling and analysis
- Analytical monitoring:
- yes
- Details on sampling:
- After 24 and 48 hours, the Daphnia magna in each test vessel were observed for evidence of immobility.
At the start of the test (0 hours) and media renewal at 24 hours, duplicate 100 mL samples of freshly prepared test media were taken from the control and 150 mg/L test media preparation flask for chemical analysis.
At 24 and 48 hours, duplicate 100 mL samples were taken for chemical analysis from the pooled expired test media from the 150 mg/L test concentration and control.
Test solutions
- Vehicle:
- yes
- Details on test solutions:
- The range-finding test was conducted at nominal test substance concentrations of 0.1, 1.0, 10 and 100 mg/L under semi-static test conditions. A control group was also included. Duplicate test vessels were prepared for the control and each test substance concentration. Based on nominal concentrations, the results of the range-finding test suggested that the 48-hour EC50 value would be greater than 100 mg/L.
Based on the results of the range-finding test which is not fully reported, the definitive/limit test was conducted under semi-static conditions at nominal concentrations of 0 (control) and 150 mg/L.
The test vessels (nominal volume 150 mL) were glass crystallising dishes covered with clear plastic petri dish lids. Four replicate test vessels were prepared for the control and each test concentration.

EFFECT PARAMETERS MEASURED: After 24 and 48 hours, the Daphnia magna in each test vessel were observed for evidence of immobility. The observations differentiated between mobile and immobile daphnids. An individual was considered immobile if, when the contents of the test vessel were briefly agitated, it did not swim during a 15-second period of observation. In addition, Daphnia magna submerged in the body of the test media and those that were held at the surface of the test media were also recorded.
TEST CONCENTRATIONS
- Range finding study: The range-finding test was conducted at nominal test substance concentrations of 0.1, 1.0, 10 and 100 mg/L under semi-static test conditions. A control group was also included. Duplicate test vessels were prepared for the control and each test substance concentration. Based on nominal concentrations, the results of the range-finding test suggested that the 48-hour EC50 value would be greater than 100 mg/L.
- Test concentrations: Based on the results of the range-finding test which is not fully reported, the definitive/limit test was conducted under semi-static conditions at nominal concentrations of 0 (control) and 150 mg/L.

- Chemistry data
The limit of detection (LOD) for Acetylfuranoside in ASTM medium using this method was 0.014 mg/L.
The analytical results showed that on preparation at 0-hour and 24-hours, Acetylfuranoside achieved a concentration of 139 mg/L and 131 mg/L (93% and 87% of nominal concentration, respectively). At the 24 hour and 48-hour exposure periods the recovery dropped to 115 mg/L (77% of nominal concentrations). The time weighted mean calculation showed that Acetylefuranoside achieved a time weighted mean measured concentration of 125 mg/L (83% of nominal concentration).
Test media descriptions
The test preparations were observed to be colourless solutions throughout the duration of the test.
Toxicity to daphnia
After 48-hours, the concentration at which no statistically significant dose related immobility occurred was 125 mg/L and therefore the NOEC was considered to be 125 mg/L.
In terms of nominal concentrations the 48-hour EC50 value was determined to be greater than 125 mg/L.
It is concluded that Acetylfuranoside was considered not toxic to Daphnia magna at nominal concentrations less than 125 mg/L under the conditions of this test.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- The 48-hour acute toxicity of Acetylfuranoside to the freshwater planktonic crustacean, Daphnia magna, was determined in accordance with the requirements of OECD Chemicals Testing Guideline No. 202 Daphnia sp. Acute Immobilisation Test (adopted April 13 2004).
The validity criteria for control immobility (=10%) and dissolved oxygen (>60% ASV) were both satisfied and the test is therefore considered valid.
It is concluded that Acetylfuranoside was considered not toxic to Daphnia magna at nominal concentrations less than 125 mg/L under the conditions of this test. - Executive summary:
The objective of the study was to determine the 48-hour acute toxicity of Acetylfuranoside to the freshwater planktonic crustacean, Daphnia magna. The study was conducted in accordance with the requirements of OECD Chemicals Testing Guideline No. 202 Daphnia sp. Acute Immobilisation Test (adopted April 13 2004).
Based on the results of a range-finding test which are not fully reported, the definitive/limit test was conducted semi-statically at a nominal concentration of 150 mg/L. A control group was also included.
At the start of the test, five juvenile Daphnia magna were added to each test vessel. The Daphnia magna in each test vessel were observed at 24 and 48 hours. The Daphnia magna were not fed during the test.
The analytical results showed that on preparation at 0-hour and 24-hours, Acetylfuranoside achieved a concentration of 139 mg/L and 131 mg/L (93% and 87% of nominal concentration, respectively). At the 24-hour and 48-hour exposure periods the recovery dropped to 115 mg/L (77% of nominal concentrations). The time weighted mean calculation showed thatAcetylfuranosideachieved a time weighted mean measured concentration of 125 mg/L (83% of nominal concentration).
