Administrative data
Link to relevant study record(s)
- Endpoint:
- short-term toxicity to aquatic invertebrates
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- other:
- Justification for type of information:
- The target substance is hydrolytically unstable with hydrolysis half-life less than 5 minute. The hydrolysis products include 1-propanol and hydrated zirconium dioxide. The ecotoxicity data of the organic parts have been well-investigated and used for read-across.
- Endpoint:
- short-term toxicity to aquatic invertebrates
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- according to guideline
- Guideline:
- other: DIN 38412 Part 11, Daphnia- Short term test
- GLP compliance:
- not specified
- Analytical monitoring:
- no
- Test organisms (species):
- Daphnia magna
- Test type:
- static

Additional information
No studies were conducted on the target substance, Zirconium tetrapropanolate. As the target substance hydrolyses rapidly (half-life < 5 minutes) the intrinsic properties are related to hydrolysis products of the target substance.
On the basis that if entering the environmental, this substance will quickly dissociate to form the inorganic (poorly soluble) zirconium dioxide and well-evaluated organic substances – 1-propanol.
The zirconium dioxide is not considered further in this report as aquatic toxicity assessments do not apply.
EC50 (48h) values tested on Daphnia magna were 3644 mg/l for1-propanol (Kuehn, et al. 1989). This value was used for CSA.
