- other: Rainbow trout fry
Study design
- Test type:
- static
- Water media type:
- freshwater
- Total exposure duration:
- 96 h
Test conditions
- Details on test conditions:
- The fish were fed a maintenance ration of a commercial pelleted trout food (Martin Feed Mills Limited, Ontario). The water supply for the continuous flow-through holding tanks was obtained from the Winnipeg River (in eastern Manitoba, Canada), purified by sand filtration and ultraviolet light sterilization, and distributed through polyvinylchloride pipes. Randomly selected fish were acclimated at I5°C (-2°C) for a period of >/5 days priorto testing. Feeding was suspended 24-h prior to and during the test period. The 96-h static tests were aerated and conducted at 15°C (±2°C) in a temperature- and photoperiod- (16-h light, 8-h dark) controlled facility. All fish holding and testing protocols followed the Ontario Ministry oft he Environment guidelines (Craig et al. 1983).

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- The acute toxicity of the substance to fish was conducted in a static test. After 96 hours of exposure a LC50 value of 4500 mg/L was obtained. No toxicity to fish was observed.
- Executive summary:
The acute toxicity (96-h LC 50 ) of aqueous stable iodine species (I – , IO 3 – , I 2 ) to rainbow trout and Daphnia magna were measured at three individual concentrations of hardness, total organic carbon, and chloride. Rainbow trout were most sensitive to I 2 (LC 50 0.53 mg/L), and much less sensitive to IO 3 – (LC 50 220 mg/L) or I – (LC 50 860 mg/L). Daphnia magna were equally sensitive to I 2 (LC 50 0.16 mg/L) and I – (LC 50 0.17 mg/L), but were less sensitive to IO 3 – (LC 50 10.3 mg/L). The external and internal radiological dose imparted by equivalent molar quantities of radioactive 125 I, 129 I, and 131 I were calculated for both the Daphnia and trout using the LC 50 values obtained from a standard water treatment. As expected, the dose from 125 I and 131 I would exceed the expected lethal dose rate long before a chemically toxic level is reached. In contrast, a molar concentration of 129 I likely to cause death by chemical toxicity would impart a radiological dose less than that expected to be lethal. Thus, for short-lived aquatic organisms, risks due to chemical toxicity of 129 I may exceed risks due to its radioactive emissions.
