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:
- As the target substance hydrolyses rapidly (half-life < 30 minutes) the intrinsic properties are related to hydrolysis products of the target substance. This information is used as a supporting evidence on the toxicity of the target substance in CSA.
- 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:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- according to guideline

Description of key information
No studies were
conducted on the target substance, Tetrakis
[[2,2',2"-nitrilotris[ethanolato]](1-)-N,O]zirconium. As the target
substance hydrolyses rapidly (half-life < 30 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
2,2',2''-Nitrilotriethanol (triethanolamine). The zirconium dioxide is
not considered further in this report as aquatic toxicity assessments do
not apply.
Short-term toxicity studies of triethanolamine are well-investigated:
Fish: LC50 (96h), Pimephales promelas, was 11800 mg/l (Geiger, D.L. et al., 1985)
Invertebrates: EC50 (24h) Daphnia magna, was 1850 mg/l (Bringmann 1982)
Algae or cyanobacteria: EC50 (72h),Desmodesmus subspicatus, was 512 mg/l (Aman and Steinhaeuser, 1986)
Microorganisms: IC50 (3h), activated sludge, > 1000 mg/l (Klecka, et al. 1985).
