- Conclusions:
- In a valid, reliable and conclusive study according to the approved protocol SOPs and OPPTS, series 850, section 1075, the effect of the test item on the mortality of Rainbow trout after 96 hours was determined. Under the conditions of the present study, the test item had no acute toxic effects on Rainbow trout in a static 96-hour test up to the nominal concentration of 225 mg/L (NOEC). The 96-h LC50 was determined to be 315.65 mg/L with 95% confidence interval of 294.39 - 338.46 mg/L. The results of the test can be considered reliable without restriction. It can be concluded that the test item 2-[(3-Aminopropyl) methylamino]ethanol is not hazardous to fish.
Reference
Description of key information
The study of Rodrigue (2007), investigating the acute toxicity of the test substance in rainbow trout according to the approved protocol SOPs and OPPTS, series 850, section 107, was considered as the key study for endpoint coverage. The 96-h LC50 was determined to be 315.65 mg/L (> 100 mg/L). Based on the results it can be considered that the test item is not harmful to fish.
