Additional information
One study valid without restriction is available. The study was performed according to OECD guideline 203 with Oryzias latipes. The test substance is not toxic to fish as can be seen from the preliminary test with adjusted pH. No fish died at 100 mg/L. Therefore the 96h-LC50 for p-TSC is greater than 100 mg/L.
Another study, valid with restrictions, is available with Danio rerio according to OECD 203. This study was performed as alimit test and gave a 96h-LC50 greater than 1009 mg/L, but as no chemical analysis were performed this study is not used as key.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
