Description of key information
Two acute aquatic toxicity tests on aquatic invertebrates (daphnia magna) and aquatic algae ( Pseudokirchneriella subcapitata) were negative with regards to acute aquatic toxicity for thioacid.
No concentration related immobility of Daphnia magna was observed in the control and all exposure concentrations during the range-finding limit test. As there was no immobility observed during the range-finding limit test, the 48-hour EC50 value and the corresponding no observed effect concentration (NOEC) for Daphnia magna exposed to Thio-Acid could not be determined. Therefore, the 48-hour EC50 value is considered to be >100mg/L, the highest nominal exposure concentration tested in the range-finding limit test.
The effect of the test item on the growth of Pseudokirchneriella subcapitata has been investigated over a 72-Hour period and based on the geometric mean measured test concentrations gave the following results:
Growth rate: EC50 : 53 mg/l, NOEC : 18 mg/l, LOEC : 58 mg/l
Yield: EC50 : 35 mg/l, NOEC : 18 mg/l, LOEC : 58 mg/l
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
