Description of key information
Very toxic (acute effects) to fish.
Key value for chemical safety assessment
Additional information
The short-term toxicity to fish was assessed by the Ministry of the Environment, Japan. The test was conducted based on OECD-GLP standard and OECD test guideline. After 92h of exposure a LC50 of 0.031 mg/L was determined.
Additionally, several publically available data on the toxicity of the compound to fish supports the above-mentioned result. A study conducted in Russia revealed a LC100 of 0.2 mg/L in roach. Pal et al. investigated the toxicity of the present compound to Cyprinus carpio. At a concentration of 0.5 ppm 4 fish (out of 8) died. Another study from Andaya et al. revealed a LC50 of 0.042 mg/L in Ictalurus punctatus.
In conclusion, the compound is regarded as very toxic to fish.
