Validity criteria fulfilled:

not specified

Conclusions:

After the exposure of test chemical with freshwater Salmo gairdneri for 48 hrs, effect LC100 were observed at 5740 mg/l.

Executive summary:

Short term toxicity study of test chemical was performed on the growth of Salmo gairdneri. Test conducted under the static system for 48 hrs. After the exposure of test chemical with freshwater Salmo gairdneri  for 48 hrs, effect LC100 were observed at 5740 mg/l. Thus based on the LC100 value, it can be concluded that the chemical was nontoxic to the fish and thus not classified as per the CLP classification criteria.

Description of key information

Short term toxicity study of test chemical was performed on the growth of Salmo gairdneri. Test conducted under the static system for 48 hrs. After the exposure of test chemical with freshwater Salmo gairdneri  for 48 hrs, effect LC100 were observed at 5740 mg/l. Thus based on the LC100 value, it can be concluded that the chemical was nontoxic to the fish and thus not classified as per the CLP classification criteria.

Additional information

Based on the short term toxicity studies available for the test chemical, studies were reviewed to determine the toxic nature of test chemical on the mortality of fish. The studies are as mentioned below:

Short term toxicity study of test chemical was performed on the growth of Salmo gairdneri. Test conducted under the static system for 48 hrs. After the exposure of test chemical with freshwater Salmo gairdneri for 48 hrs, effect LC100 were observed at 5740 mg/l. Thus based on the LC100 value, it can be concluded that the chemical was nontoxic to the fish and thus not classified as per the CLP classification criteria.

 

First study was supported by the second experimental study. Aim of this study was to determine the effect of test chemical on the mortality of freshwater fish Brachydanio rerio. Test conducted in accordance with OECD Guide–line 203 "Fish, Acute Toxicity Test". Test performed under the static system for 96 hrs. Based on the effects observed on the mortality of Brachydanio rerio, a freshwater fish due to the exposure of test chemical for 96 hrs, LC50 was observed to > 500 mg/l. Thus based on the LC50 value, it can be concluded that the chemical was nontoxic to the fish and thus not classified as per the CLP classification criteria.

 

Similar study was conducted to evaluate the effect of test chemical on the growth and mortality of freshwater fish Oncorrynchus masou. Test conducted under the static system for 96 hrs in which test chemical exposed with fishes. After the incubation period effect on the mortality were observed. Based on the effect observed on the mortality of fishes Oncorrynchus masou, after the exposure of test chemical for 96 hrs, LC50 was observed at 650 mg/l.

Thus based on the above details and studies, test chemical consider to be nontoxic to fish and not classified as per the CLP classification criteria.
