- Endpoint:
- short-term toxicity to fish
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Study period:
- 96 hours
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 203 (Fish, Acute Toxicity Test)
- GLP compliance:
- not specified
- Test organisms (species):
- Oncorhynchus mykiss (previous name: Salmo gairdneri)
- Details on test organisms:
- Young hatchery-purchased fry (6.2 + 0.7 cm; 1.7 + 0.7 g), acclimated for at least 3 weeks to the treated city water
- Test type:
- static
- Water media type:
- freshwater
- Limit test:
- no
- Total exposure duration:
- 96 h
- Hardness:
- Tests were carried out using activated charcoal and ultraviolet light-treated Longueuil-city water, whose hardness generally stands between 100 to 150 mg L -I in CaCO 3 equivalents.
- Test temperature:
- 15 +/- 0.1 deg C
- pH:
- pH (value not reported) was monitored periodically throughout the experiment.
- Dissolved oxygen:
- Aeration (7.5 cm 3 L -I min -1) of each test vessel. Dissolved oxygen (value not reported) was monitored periodically throughout the experiment.
- Nominal and measured concentrations:
- 0 (control), 0.01, 0.1, 1, 10 and 100 mg/L Zr.
- Details on test conditions:
- Exposure vessels consisted of 60 L Rubbermaid containers lined with a polyethylene bag into which was placed a black-meshed Vexar (Dupont) cylinder (with lid) espousing the contour of the assay container.
- Reference substance (positive control):
- no
- Duration:
- 96 h
- Dose descriptor:
- LC50
- Effect conc.:
- > 20 mg/L
- Conc. based on:
- element
- Basis for effect:
- mortality (fish)
- Key result
- Duration:
- 96 h
- Dose descriptor:
- LC50
- Effect conc.:
- > 54 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- other: Registered substance
- Basis for effect:
- mortality (fish)
- Details on results:
- 100% mortality within 2 hr at 100 mg/L Zr (pH-3.0), but identical effect for dilution water adjusted to pH=3.0. In the 96-hr LCs0 bioassay with rainbow trout, low pH was entirely responsible
for toxicity at 100 mg/L Zr. At 10 mg L I Zr (pH = 6.7), the next highest test concentration used in the assay, no lethal effects were observed. The LC50 was therefore initially identified as being > 10 mg L -1 Zr. However, in a subsequent sublethal bioassay carried out at 0, 1, 5 and 20 mg/L Zr, no mortality was noted at the highest concentration tested. Hence, a 96-hr LC50 > 20 mg L -1 was finally reported. - Sublethal observations / clinical signs:
The reported toxicity of zirconium 4+ ion was used to calculate the toxicity of the registered substance based on a 37% Zr w/w content
- Conclusions:
- The LC50 (96 hr) in rainbow trout (Salmo gairdneri) was reported to be >20 mg/L Zr, calculated to be 54 mg/l for the registered substance.
- Executive summary:
The LC50 (96 hr) in rainbow trout (Salmo gairdneri) was reported to be >20 mg/L Zr. Although mortality was 100% at a higher dose of 100 mg/L Zr, this was attributed entirely to the effects of pH.

Description of key information
Sodium zirconium lactate has been tested using screening methods and show to have low toxicity to fish with an LC50 > 1000 mg/l
The LC50 (96 hr) in rainbow trout (Salmo gairdneri) was reported to be >20 mg/L Zr. Although mortality was 100% at a higher dose of 100 mg/L Zr, this was attributed entirely to the effects of pH.
The Zr4+ content of the anhydrous registered substance is ca 17%; using an assumed LC50 of 20 mg/l Zr 4 +, the product LC50 is estimated > 100 mg/l
Sodium and lactate (as lactic acid) are not considered hazardous to fish at concentrations leading to classification
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 1 000 mg/L
