Results and discussion

Any other information on results incl. tables

Chemical analysis of the 100% v/v saturated solution showed that a zirconium concentration of less than the limit of quantitation, which was determined to be 0.049 mg Zr/L, was obtained.

Applicant's summary and conclusion

Preliminary stirring experiments were executed in view of acute fish toxicity testing with a loading rate of 50 mg test item/L (corresponding to 20 mg/L anhydrous zirconium acetate), sufficient to ensure 100% saturation of the test media. A measurable amount of zirconium could not be obtained in solution (LOQ = 0.049 mg Zr/L). Therefore, no toxicity test to fish was conducted for zirconium acetate.
