Description of key information
Evaluation of TK 12146 for its ability to generate acute toxicity effect in Cyprinus carpio during an exposure period of 96 hours.
Key value for chemical safety assessment
- LC50 for freshwater fish:
- 100 mg/L
Additional information
The purpose of this study was to evaluate the test substance for its ability to generate acute toxic effects in Cyprinus carpio during an exposure period of 96 hours.
The study procedures was performed according to the OECD 2303.
The definitive test was performed with carp exposed to concentrations ranging from 0.1 to 100 mg/l in a static system. Acetone was used as a solvent in the stock solution.
The 96h-LC50 for carp is > the nominal concentration of 100 mg/l. The maximum solubility was estimated to be between 10 and 100 mg/l. Hence, the testing of concentrations> 100 mg/l was not considered to be relevant.
The BWZ of TK 12146, Accelerator DY 9577 for acute toxicity in fish is <4.
