Validity criteria fulfilled:
no
Conclusions:
The lethal concentration (LC50) value of test chemical on fish (Oryzias latipes) in a 24 hr and 48 hrs study on the basis of mortality effect was estimated to be >1000 mg/L.
Executive summary:

Short term toxicity of test chemical were studied on the mortality of fish Oryzias latipes (Japanese Medaka). The lethal concentration (LC50) value of test chemical on fish (Oryzias latipes) in a 24 hr and 48 hrs study on the basis of mortality effect was estimated to be >1000 mg/L. Thus considering the value from CLP Criteria for aquatic classification of the substance, it is concluded that test chemical could not exhibit short term toxicity to fish (Oryzias latipes).

Description of key information

Short term toxicity of test chemical were studied on the mortality of fish Oryzias latipes (Japanese Medaka). The lethal concentration (LC50) value of test chemical on fish (Oryzias latipes) in a 24 hr and 48 hrs study on the basis of mortality effect was estimated to be >1000 mg/L. Thus considering the value from CLP Criteria for aquatic classification of the substance, it is concluded that test chemical could not exhibit short term toxicity to fish (Oryzias latipes).

Additional information

Summarized result for the toxicity of test chemical on mortality of fish were carried out and mention as below:

Short term toxicity of test chemical were studied on the mortality of fish Oryzias latipes (Japanese Medaka). The lethal concentration (LC50) value of test chemical on fish (Oryzias latipes) in a 24 hr and 48 hrs study on the basis of mortality effect was estimated to be >1000 mg/L. Thus considering the value from CLP Criteria for aquatic classification of the substance, it is concluded that test chemical could not exhibit short term toxicity to fish (Oryzias latipes).

 

First study was supported by the second study from secondary source. Short term toxicity of test chemical were studied on the mortality of fish Oryzias latipes (Japanese Medaka). Test conducted under the static system for 48 hrs. Based on the mortality of fish Oryzias latipes (Japanese Medaka) by the chemical incubation for 24 and 48 hrs, the LC50 was observed at 260 mg/l and 240 mg/l. Thus on the basis of LC50 value, chemical consider to be nontoxic and not classified as per the CLP classification criteria.

Thus on the basis of LC50 value, chemical consider to be nontoxic and not classified as per the CLP classification criteria.
