Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The static, 96-hour test was conducted on fathead minnow larvae (one to seven days old) with nominal test concentrations ranging from 500 to 10000 mg/L.

Key value for chemical safety assessment

Fresh water fish

Fresh water fish
Effect concentration:
680 mg/L

Additional information

No short-term toxicity to fish data were available for the test substance. Therefore, an acute fish toxicity study with potassium sulphate was used as a read across to fulfill the data gap for the test substance. The underlying hypothesis for the read-across is that the test substance hydrolyses to form sulphuric acid and potassium sulphate. At environmentally relevant pHs, sulphuric acid will ionise to form its respective sulphate ion. In water, potassium sulphate will dissociate to form potassium and sulphate ions. The potassium sulphate study was selected since the relevant species of concern is the potassium cation. Additional documentation, provided within the IUCLID Assessment Reports section, supports the read-across approach.
