ANALYTICAL RESULTS
Overall, the analytical results of the final semi-static test showed that preparation of test solutions was reproducible. Indeed, concentrations measured in freshly prepared solutions (t=0h and t= 48h) and in 24-hour old solutions revealed that the concentration of the test item was satisfactorily maintained within ± 20% of the initial and nominal concentration throughout the test. Since the deviation of the exposure concentrations of the test substance was not greater than ± 20% of the initial concentrations, it was decided to evaluate the biological effects on the nominal values for this study.

- Validity criteria fulfilled:
- yes
- Remarks:
- No mortality was observed in the control at the end of the test. The dissolved oxygen concentration was at least 60% of the air saturation value throughout the test . Results were based on nominal exposure concentrations.
- Conclusions:
- The toxic effect of the test item 1,8-CINEOLE to the zebrafish (Danio rerio) was investigated in a semi-static test. The evaluation was based on the nominal exposure concentrations. Under the experimental conditions, the 96-hour LC50 value estimated was 121 mg.L
- Executive summary:
In an acute aquatic toxicity study performed according to OECD guideline 203 and in compliance with GLP, groups (7/concentrations) of zebrafish (Danio rerio) were exposed to 1,8 -CINEOLE at concentrations of 100, 125, 157, 198 and 250 mg/L [nominal concentration] for 96 h under semi-static conditions.
The mortality of the fish was determined in a semi-static 96-hour test by visual observation after 24, 48, 72 and 96 hours. Actual exposure concentrations were determined by chemical analyses at the start of the test and every 24 hours thereafter in old and new solutions.
The test item levels were found to be relatively stable throughout the test and the evaluation of the effects on fish was based on the nominal concentrations. After 96 hours of exposure, mortality was 0% at 100 mg.L-1, 71.4% at 125 mg.L-1 and 100% at 157, 198 and 250 mg test item.L-1. It should be noted that fish exposed to the concentrations of 157 to 250 mg.L-1 died rapidly. Hence, the highest concentration resulting in no mortality at 96 hours was 100 mg.L-1 and the lowest concentration resulting in 100% mortality at 96 hours was 157 mg.L-1.
The toxic effect of the test item 1,8-CINEOLE to the zebrafish (Danio rerio) was investigated in a semi-static test. The evaluation was based on the nominal exposure concentrations. Under the experimental conditions, the 96-hour LC50 value estimated was 121 mg.L.

It should be noted that fish exposed to the concentrations of 157 to 250 mg.L-1 died rapidly.
